How to install Krita?

[bernd.wechner]

This is becoming a recurrent painful issue for me. I offer this experience which epitomises the issue, but it has happened with various packages, and if I can nail this one I have a feeling others might be solved too.

I am trying to install Krita.

Step 1: Use Software Manager.
Finds it. Great. But lists it as Not Available, Please use apt-get to install this package.
Forgive me but that strikes me as weird. But moving right along:

Step 2: Terminal window

Code: Select all

sudo apt-get install krita

Reports:

Code: Select all

The following packages have unmet dependencies:
 krita : Depends: calligra-libs (= 1:2.4.0-0ubuntu2.1) but it is not going to be installed
         Depends: libfftw3-3 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Why the F not? Is not going to be installed, what gives? So let's try by hand and see what's up?

Step 3: Terminal window

Code: Select all

sudo apt-get install calligra-libs

Reports:

Code: Select all

The following packages have unmet dependencies:
 calligra-libs : Depends: kdepim-runtime but it is not going to be installed
                 Depends: libkrossui4 (>= 4:4.4.0) but it is not going to be installed
                 Depends: libnepomuk4 (>= 4:4.5.85) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Getting tedious but let's keep going and try by had to install what's needed.

Step 4: Terminal window

Code: Select all

sudo apt-get install  kdepim-runtime

Reports:

Code: Select all

The following packages have unmet dependencies:
 kdepim-runtime : Depends: libakonadi-calendar4 (>= 4:4.7.90) but it is not going to be installed
                  Depends: libakonadi-contact4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libakonadi-kcal4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libakonadi-kde4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libakonadi-kmime4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libkalarmcal2 but it is not going to be installed
                  Depends: libkidletime4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libmailtransport4 (>= 4:4.8.1) but it is not going to be installed
                  Depends: libnepomuk4 (>= 4:4.8.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Getting the message, yes. but moving right along ...

Step 5: Terminal window

Code: Select all

sudo apt-get install libakonadi-calendar4

Reports:

Code: Select all

The following packages have unmet dependencies:
 libakonadi-calendar4 : Depends: libakonadi-contact4 (= 4:4.13.3-0ubuntu0.2) but it is not going to be installed
                        Depends: libakonadi-kde4 (= 4:4.13.3-0ubuntu0.2) but it is not going to be installed
                        Depends: libakonadi-kmime4 (= 4:4.13.3-0ubuntu0.2) but it is not going to be installed
                        Depends: libmailtransport4 (= 4:4.13.3-0ubuntu0.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

OK, next one in the chain ...

Step 6: Terminal window

Code: Select all

sudo apt-get install libakonadi-contact4

Reports:

Code: Select all

The following packages have unmet dependencies:
 libakonadi-contact4 : Depends: libakonadi-kde4 (= 4:4.13.3-0ubuntu0.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Yawn, on we go ...

Step 7: Terminal window

Code: Select all

sudo apt-get install libakonadi-kde4

Reports:

Code: Select all

The following packages have unmet dependencies:
 libakonadi-kde4 : Depends: libakonadiprotocolinternals1 (>= 1.11.80) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Come on now, please, will this ever end?

Step 8: Terminal window

Finally it installed! Phew ... what was that about, we have one of the packages it depends on? OK, back up the chain to Step 7 call it 9.

Step 9: Terminal window

Code: Select all

sudo apt-get install libakonadi-kde4

OK, failed, but more info now. Let's get some more:

Step 10: Terminal window

Code: Select all

sudo apt show libakonadiprotocolinternals1

What does that mean? I says it's installed and the version is 1.7.2-0ubuntu1 but it says that it conflicts with itself! I'm going bats here.

But it seems I have Version: 1.7.2-0ubuntu1 and the dependency is asking for (>= 1.11.80) and I'm figuring 1.7.2 is not >= 1.11.80 and this is my problem?

Can this get any harder?

Before you ask, this is all done AFTER I did:

Code: Select all

sudo apt update
sudo apt upgrade
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get check

and the last reports simply:

Code: Select all

Reading package lists... Done
Building dependency tree       
Reading state information... Done

What is going on? Main issues I am seeing is:

1) Software manager finds it but says it's not available? Huh? Help me out here, why not?
2) apt won't install it but doesn't say clearly why not only that it won't install things it depends on. Why the heck not? Install dammit! .

OK, I tried this:

Code: Select all

sudo apt-get --fix-broken install krita

Same result as step 2.

And this:

Code: Select all

sudo apt-get --fix-missing install krita

Same results again, as step 2.

Aaargh. I am at wits end slowly and as I said this is the nth package I wanted to install that this sort of stuff is happening on.

Is my OS broken? Can it be fixed? Is this usual? Why are the software manager and apt so seemingly stupid in that they provide no clear feedback as to what is wrong or what can be done about it?

Any pointers deeply appreciated. Thanking you in advance for your patience and time to have got this far with me.

Krita is a KDE program, and it probably requires a bunch of KDE libs. I have Krita running on my computer, but I had installed several KDE programs (like K3b) previously, so all the depends were already installed. I've seen a couple of threads on this forum from people who have had trouble installing KDE apps, and somebody told them to install something-or-other, but I can't remember exactly what the something-or-other was. Maybe try installing K3b and then see if you can install Krita.

...

OK, I went and did a little Googling of the forums. The something-or-other they said to install is:

kdelibs-bin
kdelibs5-data
kdelibs5-plugins

Install those and then try Krita again.

Oh well, it was worth a try. I just remembered that somebody else had a similar problem installing KDE applications, and thought maybe the same solution might apply. No such luck. Wait until xenopeek comes back, he knows much more about this stuff than I do!

HI bernd.wechner,

I just read your post and the good replies to it. Here are my thoughts on this as well.

1.) "Krita" is a raster graphics editor based on the KDE Platform. It is also a part of "Calligra" Suite which you might consider installing too.

If you are not using KDE, then just install these few programs below in the quote box in blue.

If you're experiencing issues with KDE apps (like Okular, Gwenview, KStars, kdenlive, ..etc) run the following command from your console terminal prompt: (you can copy & paste it too)
Depending on your setup, you might also need to install "KDE-runtime" as well.
sudo apt-get install kdelibs-bin kdelibs5-data kdelibs5-plugins

2.) You may also have a need to repair the software installation aspects of your system.
To repair Software Manager or Synaptic Package Manager (SPM)
and or installing software from the console terminal prompt.


sudo dpkg --configure -a
sudo apt-get install --yes --force-yes -f


Note: You cannot, or should not, install anything from the terminal while the Mint Update Manager is updating
or you have the Software Manager or Synaptic Package Manager (SPM) open at the same time, or visa-versa.

Hope this helps ...

Is there a reason you have BOTH Ubuntu Precise and Ubuntu Trusty repositories configured? The former is 12.04 the latter is 14.04. The Linux Mint repositories you have configured look like you should have Linux Mint 17.2 which uses Ubuntu Trusty as a package base. I don't get why Ubuntu Precise is there; but this is the cause of these problems as you see with apt-get policy that Krita is attempted to be installed from the Ubuntu Precise repositories--while the rest of your operating system is based on Ubuntu Trusty--two years into the future as seen from Ubuntu Precise.

I suggest you first check if any packages have been installed from Ubuntu Precise (we'll fix these later, just share the output [if any] here with me):

Code: Select all

aptitude search -F "%p %V" "?narrow(?installed,?archive(precise))"

Then go ahead and delete the file /etc/apt/sources.list to remove the Ubuntu Precise repositories.

Code: Select all

sudo rm -v /etc/apt/sources.list

Next I suggest cleaning up a bit with:

Code: Select all

sudo apt-get autoclean
sudo apt-get update

Then you should be able to install Krita. As per the release notes of Linux Mint 17.2, first run this command to install needed KDE base:

Code: Select all

sudo apt-get install kdelibs-bin kdelibs5-data kdelibs5-plugins

Hey, thanks very very deeply for the time and attention. This is certainly an odd experience for me.

But let me first capture the output of:

But the story of how I got that is riddled with oddness and involves a system restart.

Let me just record now that I can do this:

Code: Select all

bernd@bigfoot ~ $ apt search krita
p   krita                           - pixel-based image manipulation program for
p   krita:i386                      - pixel-based image manipulation program for
p   krita-data                      - data files for Krita painting program     

That is relevant because after I do this:

Code: Select all

sudo rm -v /etc/apt/sources.list
sudo apt-get autoclean
sudo apt-get update

apt search krita returns nothing. Nor can the Software Manager find krita.

And now:

Code: Select all

aptitude search -F "%p %V" "?narrow(?installed,?archive(precise))"

returns nothing. Grrr.

Now repositories are search as I can find gimp, libreoffice and blender without problems to pick some random things I use, and Software Manager can browse packages.

Now if I return /etc/apt/sources.list (given I took a backup copy before removing it) nothing changes (i.e. can't find krita). If I reboot, I'm back where started form (beginning of this post - i.e. can find krita).

So I'm thinking apt needs to asked explicitly to reload sources.list perhaps? But it works to remove it, so not. Bizarre and confusing.

Oh and contextually:

Is there a reason you have BOTH Ubuntu Precise and Ubuntu Trusty repositories configured? The former is 12.04 the latter is 14.04. The Linux Mint repositories you have configured look like you should have Linux Mint 17.2 which uses Ubuntu Trusty as a package base. I don't get why Ubuntu Precise is there;

No reason at all. I was unaware it was. So perhaps more accurately, there must be a reason I just don't know what it is and how it got to be that way? I cannot rule out having put it there myself at an earlier date for some forgotten (and clearly bad) reason.

Yes I'm on Mint 17.2 indeed.

Also I did this (which phd21 recommended):

Code: Select all

bernd@bigfoot ~ $ sudo apt-get install kdelibs-bin kdelibs5-data kdelibs5-plugins 
Reading package lists... Done

Upon second look, you have removed part of the Linux Mint official repositories. I suggest opening Software Sources from your menu and clicking to reset the default settings.

Alternatively, as root edit the file /etc/apt/sources.list.d/official-package-repositories.list and add the lines:

Code: Select all

deb http://packages.linuxmint.com rafaela main upstream import
deb http://archive.ubuntu.com/ubuntu trusty main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu trusty-updates main restricted universe multiverse

You'll likely want to add appropriate lines to /etc/apt/sources.list.d/official-source-repositories.list as well for the same.

Afterwards run:

Code: Select all

sudo apt-get update

Thanks, thanks a million times thanks! To everyone who lent a hand.

Indeed the fix ultimately was, in Software Manager to reset to default settings for sources, and the do an update and all came good.

Somehow, somewhen perhaps a few weeks ago my repository configs got screwed up it seems.

I do however have the sad experience that when that goes awry (for whatever reason) that the feedback provided by the aptitude family of tools is rather poor and unclear sadly. But I don't foresee a need to fix this fast, as there clearly hasn't been in past as a) it's probably not going to happen unless you do something weird (I'm prone to and so won't affect the vast majority of users and b) there is in fact a good community in the forums that is helpful and patient. Both relevant points as I'm trialling Linux (again after a decade of absence - I grew up on Unix systems) with a view to seeing if it has evolved far enough to recommend to my family members ... am still not 100% sure, but it's certainly very close and the jury is out .

In software manager if you go to flatpak and look around you will find org.kde.krita.
This is the solution to getting the app not completely secure but it works. I am not sure how to get it in terminal but otherwise problem solved
