Hi,

The system is Ubuntu Noble with a regular daily updates.
This happens many times since few days ago but not clear

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

Applying:
$ ubuntu-bug /var/crash/_usr_bin_gnome-shell.1001.crash
is failing due to the availability of certain package updates.

[Daniel van Vugt (vanvugt)]

Please try using apport-cli if ubuntu-bug fails, but I guess both might fail if any packages are out of date.

I'm guessing this crash is due to some extension because nobody else is reporting it, and because you seem to have so many extensions installed. And because the crashing code seems to be called directly from some Javascript. So please try removing gnome-shell extensions from the system.

But the .crash file is a text file, isn't it?

How do you see «so many extensions»?

$ dpkg -l | grep gnome-shell-extension
ii gnome-shell-extension-appindicator 57-2 all AppIndicator, KStatusNotifierItem and tray support for GNOME Shell
ii gnome-shell-extension-desktop-icons-ng 46+really47.0.9-1 all desktop icon support for GNOME Shell
ii gnome-shell-extension-prefs 46.0-0ubuntu4 amd64 tool to enable / disable GNOME Shell extensions
ii gnome-shell-extension-ubuntu-dock 89ubuntu4 all Ubuntu Dock for GNOME Shell
ii gnome-shell-extension-ubuntu-tiling-assistant 46-1ubuntu1 all extension which adds a Windows-like snap assist to GNOME Shell
ii gnome-shell-extensions 46.0-1 all Extensions to extend functionality of GNOME Shell

Most of them are dependencies of ubuntu-desktop, no?

I know that there is also bijiben installed that is crashing regularly.
I will remove this one for sure.

[Daniel van Vugt (vanvugt)]

A lot of extensions are listed in ShellJournal.txt but maybe they're not active? Looks like they came from 'gnome-shell-extensions' which we don't install by default. So try uninstalling 'gnome-shell-extensions'.

[Patrice DUROUX (patrice-duroux)]

Ok regarding my env:

$ gnome-extensions list --enabled
$ gsettings get org.gnome.shell enabled-extensions
@as []

I did not removed gnome-shell-extensions because this will break the gnome-core installed.

It crashed again this morning:
