[snap] Chromium with core24 base won't start: desktop-launch not found

[Tom]

Today I was prompted to update my chromium snap, so I closed it down and the auto-refresh happened. When I tried to launch it, it did not come up. Running `chromium` from the command line resulted in the following error:

$ chromium
Content snap command-chain for /snap/chromium/2905/gnome-platform/command-chain/desktop-launch not found: ensure slot is connected

Browsing the internet, I found people saying that gnome needed to be connected. Running `sudo snap connect chromium:gnome-46-2404 gnome-46-2404:gnome-46-2404` did not fix the problem.

I'm not sure it matters for a snap, but this is (very recently updated) ubuntu 22.04 running KDE on x86_64.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Maxim Wirt (mvirt)]

The same error on Ubuntu 24.04 / x86_64

[Dr Maria Brandl (regenspatz)]

Same on Ubuntu 18.04.

sudo snap revert chromium --revision 2897

took me back to the previous, functioning version of chromium.

snap refresh --hold=24h chromium

is also useful to stop further updates for a while.

[Serik Kozhabaev (shiko15)]

As it was suggested by the people above, I ran this command below
> sudo snap revert chromium --revision 2897
But for some reason it gives me this error message:
error: cannot revert "chromium": cannot revert inactive snaps

[Mingi Hwang (goonmandu)]

Can confirm on Ubuntu 20.04, amd64, but with different error message.

Reverting to Revision 2897 as mentioned in #3 solved the issue.

[Nathan Teodosio (nteodosio)]

Can you also please add the result

  snap info --verbose chromium|grep -q core24 && { snap connections chromium; snap list|grep -P 'mesa|gnome-\d|core2'; }

if not empty? (Stable was rolled back to use core22 to fix the problem so if you already got it updated it will return nothing).

[Dr Maria Brandl (regenspatz)]

Not sure how to address #4, but wonder whether revision 2897 is available on his installation.
On my computer:
ls -l /snap/chromium/
produced:
drwxr-xr-x 12 root root 190 Jun 25 18:31 2897
drwxr-xr-x 11 root root 179 Jul 3 17:23 2905
lrwxrwxrwx 1 root root 4 Jul 7 16:45 current -> 2897

[Nathan Teodosio (nteodosio)]

I reverted Chromium stable channel to core22 (revisions 2897 for x64 and 2899 for aarch64). It would still be valuable to investigate what exactly is going on here with core24 (on candidate channel, revisions 2905 and 2906), which is what triggered this bug, especially regarding the connections as asked in #6 and #7.

[Nathan Teodosio (nteodosio)]

Hi Dr Maria Brandl, thanks but it seems you already got the snap reverted to the core22 version so this won't be of use for debugging. I updated #6 to make that clearer.

[Dr Maria Brandl (regenspatz)]

Reverted back to revision 2905 and updated #10 and #11.

Revision 2905 now behaves as expected, also resilient to operating system shutdown and restart.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Dr Maria Brandl (regenspatz)]

Being back on revision 2905:

snap info --verbose chromium|grep -q core24 && { snap connections chromium; snap list|grep -P 'mesa|gnome-\d|core2'; }

returns:

snap info --verbose chromium|grep -q core24 && { snap connections chromium; snap list|grep -P 'mesa|gnome-\d|core2'; }

[Tom (teeks99)]

I can confirm that after a `snap refresh` I'm at 2897 and things are back to working order.

[Jim Muchow (jdavidm)]

My version of this bug was declared a duplicate (which it is). As I wrote, I simply reset my box and the problem was "fixed" and it has stayed so. I don't know what that means.

xyz@optiplex:~$ ls -al /snap/chromium
total 8
drwxr-xr-x 4 root root 4096 Jul 5 06:37 .
drwxr-xr-x 22 root root 4096 Jul 5 06:36 ..
drwxr-xr-x 12 root root 190 Jun 25 12:31 2897
drwxr-xr-x 11 root root 179 Jul 3 11:23 2905
lrwxrwxrwx 1 root root 4 Jul 5 06:32 current -> 2905

Is there anything more I can do to help?

[Serik Kozhabaev (shiko15)]

I tried other old solutions on the Internet before I found this thread so unfortunately in #4 I deleted my chromium along with its configs and data. I reinstalled 2897 and now everything works fine but my extensions/bookmarks/history are all lost(

[Nathan Teodosio (nteodosio)]

#4 does not cause Chromium configuration and data files to be deleted.

Look into $HOME/snap/chromium or even for saved snapshots with 'snap saved'.

[Nathan Teodosio (nteodosio)]

Jim Muchow, no, thank you, the problem is under investigation by the Snapd team.
