Gnome-shell segfault libmalcontent-0.so.0.14.0

Ubuntu Support Template

Ubuntu Version: 26.04 (post 26.04 release date I did do-release-upgrade -d from 24.04)

Desktop Environment (if applicable):
GNOME

Problem Description:
Issue started as not being able to use Settings > Apps. When clicking on apps I was able to force crash Settings.

=> /var/log/kern.log <==
2026-04-28T12:05:08.069368-06:00 machine kernel: Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7

What I’ve Tried:

apt install --reinstall gnome-control-center libmalcontent-0-0 malcontent

I’ve tried various incantations like the above attempting to reinstall ubuntu-desktop and it’s dependencies as well.

I’m now unable to login to my machine via the GUI. On boot GDM starts, I can click on my username, type in the password, and then it looks like login will proceed but then kicks me back to the login screen. Looking at the logs I still get the same error message.

I am still able to ssh into the machine.

Are you familiar with Friendly Recovery?

At the Grub boot menu select Advanced Options for Ubuntu. Then select a Linux kernel with recovery mode. That may load Linux to the Recovery Menu.

Select Network. That will set up an internet connection using settings already registered in the operating system.

Once you have an internet connection you can select dpkg - repair broken packages.

After that you can select Root. That will give you a command prompt where you can run commands such as the update/upgrade commands. When you are finished type exit to return to the recovery menu. Now, select Resume. The system may load to a desktop using an open source video driver.

A reboot should load with the proprietary driver if you are using one.

Regards

How would booting into recovery help? I can already ssh into the system and all the packages seem to be installed fine.

dpkg –-configure -a and apt -f install do nothing.

It appears theres an issue with libmalcontent.

papamoose · April 28, 2026, 9:40pm

I’ve now done the following:

apt-get --purge remove malcontent libmalcontent*
apt-get install --reinstall $(apt-cache show ubuntu-desktop|grep Depends:|sed -e 's/Depends: //g' -e 's/,//g')

Restart gdm so I can log in again

systemctl restart gdm

Attempting to login now works fine.

However when I attempt to launch Settings > Apps The settings application crashes.

When clicking on “Apps” I’ve run tail -f /var/log/*log

I am actually surprised you were able to upgrade from 24.04 LTS to 26.04 LTS using the do-release-upgrade -d command because the -d switch usually upgrades to the development version which is now 26.10.

Official guidance

Upgrades to the latest LTS release become available after the first point release, such as with Ubuntu 24.04.01. This usually happens several months after the initial release.

Official upgrade Ubuntu guidance

g-schick · April 29, 2026, 5:47am

Have you already checked existing threads Best practice for a successful release-upgrade to 26.04 and Do-release-upgrade not working?

peterwhite23 · April 29, 2026, 3:41pm

Maybe that’s not what happened. As discussed in the other thread, it may have upgraded to the latest interim release (25.10 or maybe even 26.10), to which there is no defined upgrade path, since there are multiple interim versions in between.

P.S.: What does this say?:

cat /etc/os-release

Actionparsnip · April 29, 2026, 3:45pm

If you make a fresh Ubuntu user and log in as that, is the system OK? This would show it is a problem with the user config or not

papamoose · April 29, 2026, 5:04pm

I’m aware that if I want to have a good experience I should wait for the .1. The idea here was not to wait so that such issues would be found and could be fixed before the .1 is released.
Logging in with a new/second user does not change the behavior. Settings > Apps still crashes.
/etc/os-release shows I am on Resolute.

# cat /etc/os-release 
PRETTY_NAME="Ubuntu 26.04 LTS"

Checking my sources.list* we can see that it is set to resolute.

# grep -i suites /etc/apt/sources.list.d/ubuntu*
/etc/apt/sources.list.d/ubuntu-main.sources:Suites: resolute resolute-updates
/etc/apt/sources.list.d/ubuntu-security.sources:Suites: resolute-security

I then ran check to see which packages on my system were not from the resolute repo. Some of them will be because some PPAs/apt repos don’t use the proper suite name.

# apt-show-versions $(dpkg-query --show | awk '{print $1}'| paste -d' ' -s)|grep -viE 'Not installed|No available|not available for' > installed.txt 

### a quick skim of this command shows `apt-show-versions` to be probably an ok method.
# apt-cache policy $(dpkg-query --show | awk '{print $1}'| paste -d' ' -s)|less

The packages that are not from resolute repos were expected (cuda and a couple of apps which don’t use the suite name that match “resolute”).

That’s a fancy way of doing

apt list '~i'

Looks like someone didn’t follow the release upgrade recommendation to uninstall 3rd party packages.

papamoose · April 29, 2026, 6:06pm

apt list '~i'

TIL. Thanks.

Looks like someone didn’t follow the release upgrade recommendation to uninstall 3rd party packages.

Who said I didn’t do that during the upgrade?

Meanwhile I figured out the issue.

Quit anyway? (y or n) y

Attempting to find that desktop file turns up this file:

$ cat /var/lib/snapd/desktop/applications/OLD_SNAP_APPLICATION_THAT_DIDNT_GET_REMOVED_PROPERLY_MISSING_EXEC_LINE.desktop 
[Desktop Entry]
X-SnapInstanceName=TITLE_OF_OLD_SNAP_APPLICATION
Version=1.0
Name=TITLE_OF_OLD_SNAP_APPLICATION
Comment=Program does a thing
Icon=/snap/TITLE_OF_OLD_SNAP_APPLICATION/636/usr/share/icons/hicolor/256x256/apps/TITLE_OF_OLD_SNAP_APPLICATION.png
Terminal=false
Type=Application
Categories=SomeCategory;Qt;

This returns no results.

$ snap list |grep -i TITLE_OF_OLD_SNAP_APPLICATION

I believe I attempted to install this application a while back (while running 24.04) via snap.. but never was able to get it removed properly.

So then we just remove the desktop file which I didn’t want anyway.

$ sudo rm /var/lib/snapd/desktop/applications/OLD_SNAP_APPLICATION_THAT_DIDNT_GET_REMOVED_PROPERLY_MISSING_EXEC_LINE.desktop

And then Settings > Apps opens as expected.

I don’t think this should be a thing though… Settings>Apps should handle this issue more gracefully.

Question, did you redact the original name, or is that the actual title?

Snaps can be purged, just like apt packages:

snap remove --purge <snap app>

papamoose · April 29, 2026, 6:45pm

did you redact the original name

I redacted the original name of the application.

The name of the application does not matter for this context. gnome-control-center should handle *.desktop files without an Exec= line more gracefully.

snap remove --purge <snap app>

Yeah it’s been too long now… so I don’t quiet remember… but I for sure tried that and all the normal things to uninstall the snap.

Maybe you should check:

debsums -s

I also just now remember having had strange segfaults with a “mixed” distro upgrade. Turned out I had stale libs in /usr/local, which the dynamic linker prefers because of that prefix being first in the search order. So this could be a case of mismatched libs.

papamoose · April 29, 2026, 11:52pm

debsums -s returns nothing.

peterwhite23 · April 30, 2026, 5:31am

As it should with all packages intact.

Anything in /usr/local/lib? Or, circling back to the previously mentioned stale libs case:

ldd $(which gnome-control-center) | grep -F /usr/local
