I can't update&upgrade anymore @ UM 18.04 v2 LTS.
Update-Manager don't open.

I do in Terminal:

/usr/bin/update-manager

May be it is worth to try reinstall update manager with apt?

#8

A segmentation fault is normally something serious. It could be a problem with your system's installation of Python since the programs you are trying to run are written in Python.

However, all these could be failing because of a problem with Apt. Check the output of /etc/apt/source.list and clear the /etc/apt/sources.list.d/ folder (as superuser) to remove any third party sources, and refresh the cache:

sudo apt update
#9

"done"

I removed Update-Manager, re-installed it, error isn't gone:

I run:
software-properties-gtk
=Segmentation fault

update-manager
=Segmentation fault

a week ago I was able to update my system.

I'm going to assume you are able to apt install and apt update successfully, and none of the Python applications (update-manager, software-properties-gtk, do-release-update) are able to start. It's possible :ubuntu_mate: Software Boutique will crash too.

Check the correct Python modules are being loaded. What is the output of this command?

python3 -c "import sys; print('\n'.join(sys.path))"

This should output (on 18.04):

/usr/lib/python36.zip
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

If it does not, does running this work?

export PYTHONPATH=/usr/lib/python3.6:/usr/lib/python3/dist-packages
update-manager

If it still segfaults,try reinstalling these main dependencies of update-manager in case they are corrupted:

sudo apt install --reinstall python3-update-manager update-manager-core gir1.2-gtk-3.0 python3-gi python3-dbus python3-aptdaemon.gtk3widgets

The stacktrace (and code) suggests to me part of the program isn't initialising properly (likely one of the libraries/dependencies) and crashes the application as a result.

Since you say you were able to update a week ago, presumably some recent updates have broken the system? Maybe paste us a snippet of your /var/log/apt/history.log (and place in code tags please)

#12

python -c "import sys; print('\n'.join(sys.path))"

Output:
/usr/lib/python2.7
/usr/lib/python2.7/plat-x86_64-linux-gnu
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/home/user/.local/lib/python2.7/site-packages
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages/gtk-2.0

Something wrong?

I completly removed these packages:
update-manager
ubuntu-release-upgrader-gtk
update-notifier
update-notifier-common
update-manager-core
python3-distupgrade
python3-update-manager
ubuntu-release-upgrader-core

I can run Updates/Upgrades via Synaptic.

In my apt. log are only entries from today.

So, these packages need I to install again right?

python3-update-manager update-manager-core gir1.2-gtk-3.0 python3-gi python3-dbus python3-aptdaemon.gtk3widgets

Are these packages enough? Or are they missing packets?

#13

Sorry, I made a typo. It should be python3 (not python). I amended the post, my bad. :man_facepalming:

python3 -c "import sys; print('\n'.join(sys.path))"

You could try reinstalling these key dependencies (GTK GI bindings, Python GI & DBus)

sudo apt install --reinstall gir1.2-gtk-3.0 python3-gi python3-dbus python3-aptdaemon.gtk3widgets

:point_up: You probably wouldn't want to remove/purge them explicitly since that might remove many applications that depend on them.

Then try installing the software - which will automatically install the other packages it depends on:

sudo apt install update-manager

Since you're able to use Synaptic and Apt via the command line, I'm pretty sure it's a problem with your system's installation of Python. These applications are based on python3.

#14

An error saying segmentation fault (or segfault , or SIGSEGV ) in Ubuntu and other Unix-like operating systems, or saying general protection fault in Windows, is when a program attempts to access a part of memory that cannot be accessed, or which the program is prohibited from accessing.

you need to remove /var/lib/ubuntu-release-upgrader/release-upgrade-available

and then run /usr/lib/ubuntu-release-upgrader/release-upgrade-motd

@ lah7
python3 -c "import sys; print('\n'.join(sys.path))"

I re-installed the packages.

@ LordBoltar, I use FireJail + AppArmor in Ubuntu Mate.

The folder /var/lib/ubuntu-release-upgrader is empty.

The forum here means: (Segmentation fault)

Very basically, it means your program is trying to access a memory area it is not suposed to.
2. To the current directoy.
3. You need to make sure your program doesn't do 1..

That's weird:

update-manager = Segmentation fault
software-properties-gtk = Segmentation fault
