[solved]unable to install kcachegrind, unmet dependencies

[santiagorf]

Hi all,
When I tried to install kcachegrind, I get the following message:

Code: Select all

sudo apt-get install kcachegrind
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kcachegrind : Depends: kde-runtime (> 4:4.10) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I tried running

Code: Select all

sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

to no avail.

Code: Select all

cat /etc/apt/sources.list.d/official-package-repositories.list

I'm running LMDE with cinnamon.
any help would be much appreciated!!

I tried running

Code: Select all

sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

to no avail.

Never use apt-get upgrade. Use apt-get dist-upgrade.

Code: Select all

The following packages have unmet dependencies:
 libvlccore7 : Depends: vlc-data (= 2.1.1-1) but 1:2.0.8-dmo2 is installed.

Here's a great example of not fully upgraded system because the user mistakenly used apt-get upgrade instead of apt-get dist-upgrade.
Fix it first before trying anything else:

Code: Select all

apt update && apt dist-upgrade

[kurotsugi]

assuming you have cinnamon run 'sudo gedit /etc/apt/conf.d/debmulti.list' then add this line

Code: Select all

deb http://www.deb-multimedia.org testing main non-free

run 'sudo apt-get update' followed by 'aptitude -s install kcachegrind'.

[Monsta]

This is not needed, kcachegrind is installable without adding any external repos. I already described what the problem is.
Sometimes it really helps to read all the recent posts before posting anything.

[santiagorf]

thanks for the help. I run

sudo apt update && sudo apt dist-upgrade

, but it didn't install (or remove) any package.

[Monsta]

The "apt" script does not need sudo, it already uses it internally.

Obviously, some malicious person wanted to bork your system and had set the priority of this repo to 10. No wonder you get the conflicts.

I'm the only user of this computer. How come something like this might have happened?

Code: Select all

 cat /etc/apt/preferences

monsta is right. something is suspicious here.

let's check into that file

Package: *
Pin: origin repo.mate-desktop.org

[kurotsugi]

delete that file or move it into somewhere else. it should solve our problem here

[santiagorf]

Thank you guys!!
Moving the mate file solved the issue!!
I didn't mention I had also installed MATE since I didn't remember it was there.

I have two questions though.
1) Since now /etc/apt/preferences.d/mate no longer exists, will I be able to keep MATE up to date?
2)Why mate was conflicting with KDE packages?

[kurotsugi]

yes it will. but it might be better if we check your repository once more.

Code: Select all

inxi -r 
apt-cache policy mate-desktop

mate is not conflicting with KDE. it's just that you might have installed mate from outside mint/debian's repo and unconciously block the other repo.

[Monsta]

1) Since now /etc/apt/preferences.d/mate no longer exists, will I be able to keep MATE up to date?
2)Why mate was conflicting with KDE packages?

Looks like you still don't understand it. You're thinking in terms of some packages conflicting with each other, and at the same time you're toying with the repository priorities. This is not recommended for newbies and totally not recommended to do without thinking first.

Code: Select all

 cat /etc/apt/preferences.d/mate
Package: *
Pin: release a=testing
Pin-Priority: 10

This essentially sets a very low priority for any package coming from Debian Testing, including LMDE's Update Pack repos (because they are basically the frozen snapshots of Testing repos). This is the reason your system is not up-to-date - even dist-upgrade won't upgrade the packages because it complies with the repo priorities.

For now, remove that file and run

Code: Select all

apt update && apt dist-upgrade

to fully upgrade the system and don't touch the preferences files without a good reason.

For the future reading, if you'll want to know more about how the repo priorities/preferences work, carefully read this:

Code: Select all

man apt_preferences

and also LMDE FAQ, section "AptPinning".
