nemo-desktop crash after installation

[blizz]

Hello,

I created a backup of my system with systemback and after installign it the nemo-desktop crash, see attach report and screenshot.
This causing the desktop icons to be missing and I cannot right click on it.
Also the file manager is not opening.

Any idea how to solve it?

Here is the error report:

[AZgl1800]

I did not bother to read all of that, simply because my first thought is,

Why did you not use Timeshift to backup to where your system is working like it should be?

If you aren't using Timeshift, you should be.
This is precisely what it created for, recovering from bad installations.

[blizz]

Well, because I wanted to create a LIVE ISO file.
And also to clone the same system on a different computer.

[mikeflan]

Apparently blizz is trying to use the "System Copy" part of Systemback. So he creates an "iso" of his system, burns the iso to another computer, and it fails to some degree. It sure would be nice if we had a reliable way to burn our own OS iso's.

It appears development and support for Systemback stopped in 2015:
https://launchpad.net/systemback
Which makes it really hard to work on something like this.
Yet Systemback "System Copy still works for many people on LM20.0, like rickNS:
viewtopic.php?p=1996607#p1996607

More info on blizz's system is here:
viewtopic.php?p=1997748#p1997748

Thank you blizz for posting all this strace info. Please edit your first post and place it in code tags </>.

[rickNS]

Which makes it really hard to work on something like this.
Yet Systemback "System Copy still works for many people on LM20.0, like rickNS:

Yes Mike, the simple ("relatively" speaking, and for lack of a better term, AND no offense to the creator) code has no dependency issues with Mint 20. Systemback's "live system create" works the same as it always has.

Please edit your first post and place it in code tags </>.

Good point also, someone... should report it so it "gets fixed"

[rickNS]

Hello,
Any idea how to solve it?

No.

First you should put your terminal output inside of code tags (the little symbol </>) above when you're making your post.

Second, I have a couple of "maybes" for you. Maybe, because I don't use cinnamon, and I haven't seen your "problem" before...so

1) Maybe, try restarting Cinnamon instead of NEMO, (yes I saw the error report, but...)
Restart Cinnamon;
Alt + F2 then type r in the box, then enter

probably won't help, but won't hurt either.

2) Maybe try reinstalling Nemo;
sudo apt-get install --reinstall nemo
Again no guarantee that will work, (but also again won't hurt, and if it does work, we can make that happen automatically later).

3) and I guess lastly, since you seem fairly new, and not yet "addicted" to any particular DE, you could start over using MATE. (hope that doesn't start a flame war)

[venks]

Hi,
I am having the same issue as with blizz. That is after instaling a Systembacked image, I cannot right click on the desktop to get the context menu and there are no desktop icons even thought in the setting it is says show icons. Again this is on a freshly created user.

I installed my Systemback from an installation pack called Systemback_Install_Pack_v1.8.402.tar.xz . Part of the instruction was to remove 'casper' package and so I did.

Any new progress in getting the nemo to run and desktop right click working? I have already tried re-installing nemo and cinnamon but no improvement.

[mikeflan]

Do a search for systemback on this forum and you will see topics like this:
viewtopic.php?f=47&t=346461

As a workaround, you might use a cloning program like Foxclone to clone the whole drive, or clone the partition. Then burn the image to the new drive.

[venks]

Hi,
the reason I didn't want to use a cloning software is that it will be tied to a particular machine/hardware. I want a remastered ISO image so that I can installed on to many different types of computers within the same organisation. This will simplify configuration for each machine considerably.

I took a look at Foxclone, but then it is a backup software much similar to Clonezilla. So this is not what I want to do.

I am still wondering why nemo / nemo-desktop is still crashing on the installed machines. When running from the live ISO image, everything works fine. After installation it behaves differently.

[mikeflan]

the reason I didn't want to use a cloning software is that it will be tied to a particular machine/hardware.

This is a common misconception - at lease in my case. I have at least 5 desktops (actually more, but I have not tried them all) and as of this weekend, 5 different SSD's with LM on them. All SSD's have LM 19.3 with Timeshift and /home/ stored on those drives. Just this weekend I plunked in a SSD and it booted up fine. I didn't check all the software, but everything I tried worked perfect with no adjustments. And that old computer had Win XP on it! I was real surprised that it had the modern Sata connections and 4 GB ram.

I have never had it fail to just put an SSD in a computer and it starts up immediately. Sure is nice. I don't know how it works, because all these machines are wildly different. Some even have onboard graphics. I haven't even gone into the graphics to see what it is using - it just works. I encourage others to try this and report if they have any failures. It's incredibly easy to try if you have LM on an SSD and a new machine to try it on. It only takes 2 minutes.

I want Systemback working also, but I really don't need it.

[venks]

My experience is not very good with this type of cloning. Something or other will break. Plus each has different size HDD and some with SSD etc. Usually I will have two or three system partitions with the previous version still intact if the newer install fails to work. So each PC is very different in installed partition etc.

[venks]

I found a work around for the installation problem.
I can make the live ISO image using systemback but when installing on another machine, use Ubiquity. This is the Mint Installer it works quite well.

First use synaptic and select:

• ubiquity-frontend-gtk

• ubiquity-frontend-gtk-panel

• ubiquity-slideshow-mint

• grub-efi

Synaptic may also pull in other dependencies.

Then do your usual stuff with SystemBack, create the live ISO image.
On the machine you want to install, you will need to start ubiquity from the command line. Open a terminal and type ubiquity
During Installation there will be an error about "ubi-prepare failed with exit code 127 ...", just click on "Continue anyway".
You should be able to install without too much of trouble after that.

When I installed on a machine with pre-existing partitions, the installation stalled at the end after installing grub. It said something like "copying installation log to..." but did nothing. So I restarted the PC and everything was OK. I am not sure if this happened because I installed on an existing partition or because there was internet connection.

On another PC I did "erase disk" option for full installation but this PC was disconnected from the network, thus no internet. The installation ended normally with "Do you want to restart.." or something like that.

Hope this helps someone.

[mikeflan]

This is intriguing. Can you give us a high-level summary of what you do?

I can make the live ISO image using systemback but when installing on another machine, use Ubiquity.

So you create a live ISO image using systemback on machine 1. Which results in a single iso file??
Then you put that iso file on a USB and plug the USB into machine 2.
Then you do what?

Then I run ubiquity from the terminal on the live system. Go through the installation steps as per normal (except for those errors and some glitches), until installation is complete.

High-level summary:

• Install ubiquity on your Mint installation that you want to remaster.

• Use Systemback to do the snapshot and create ISO.

• On machine 2, boot into this live system.

• Run ubiquity from the terminal.

• Go through the installation processes (minding the glitches).

• Finish the install and reboot.

Well the important thing is that the desktop and nemo on the newly installed machine works without any problem.

[venks]

I am not sure if I should post this here, but I used another tool to do the re-imaging and installation. It is called Refracta and can be found here --> https://sourceforge.net/projects/refracta/files/tools/.

The latest versions are compatible with Ubuntu based systems like Mint. It has its own installer. You must take note that it requires more disk space for working. You will have to download :

• refractasnapshot-base

• refractasnapshot-gui

• refractainstaller-base

• refractainstaller-gui

The installer is very basic, may drop you to the command line for certain things, so be prepared to do somethings like installing grub by your self.

When booted to the newly installed system, there was no splash screen because for some reason /etc/defaut/grub was missing. So I had to copy that file from /usr/share/grub2/default/grub (I think) to /etc/default/

After that everything is perfect.
