Firefox doesn't work after 23.10 upgrade

[Rick]

Firefox doesn’t work after upgrading from 23.04 to 23.10 beta.
The Firefox icon disappeared from my sidebar during the upgrade process.
'snap list' shows firefox stable is installed, trying to run the command firefox says:
Command '/usr/bin/firefox' requires the firefox snap to be installed. Please install it with: snap install firefox

$ lsb_release -rd

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

What does ls -l /snap/bin/firefox tell you?

[Julian Andres Klode (juliank)]

Submitter says snapped firefox is installed but snapped firefox binary isn't found, probably needs more triaging

[Heinrich Schuchardt (xypron)]

apt-get install firefox --reinstall

should run debian/firefox.preinst which is responsible for installing the snap.

The preinstall script depends on /run/snapd.socket existing. So when the snapd service is stopped the snap will not be installed.

Would it be preferable to let debian/firefox.preinst return an error if the socket does not exist?

[Sebastien Bacher (seb128)]

hum, what's the output of

$ snap info firefox

and why would snapd be stopped?

It looks like my issue is related to this bug

I followed the steps in this post to fix my firefox
https://discourse.ubuntu.com/t/ubuntu-23-10-beta-testing/38861/9
snap refresh --channel=latest/stable/ubuntu-23.10 firefox

Firefox however semi broke again yesterday (clicking the icon didn't open it)
$ firefox
Content snap command-chain for /snap/firefox/3166/gnome-platform/command-chain/desktop-launch not found: ensure slot is connected

$ snap refresh
fixed firefox this time for me

I tested an upgrade from Lunar to Mantic today using ubuntu-release-upgrader version 23.10.7 which changed the snap update process from `snap refresh` to `snap switch` and still encountered this issue.

bdmurray@clean-lunar-amd64:~$ /usr/bin/firefox -h

Command '/usr/bin/firefox' requires the firefox snap to be installed.
Please install it with:

snap install firefox

bdmurray@clean-lunar-amd64:~$ snap info firefox

I then ran snap refresh firefox:

bdmurray@clean-lunar-amd64:~$ snap refresh firefox
firefox (stable/ubuntu-23.10) 118.0-1 from Mozilla\u2713 refreshed

and /usr/bin/firefox worked again.

[Brian Murray (brian-murray)]

Revisiting my upgrade test in comment #7 I booted the Lunar virtual machine I used for upgrade testing and discovered that the firefox snap on it was quite out of date. I performed the upgrade test again, but this time I refreshed the firefox snap before the distribution upgrade and all was well.

I also was unable to verify this bug after an upgrade from 23.04 to 23.10 today.

I had previously verified this bug in my VM. Maybe it was fixed by other changes in the upgrader or maybe the Firefox snap had time to update itself before I performed the upgrade.

[Sebastien Bacher (seb128)]

the upgrader shouldn't make a difference there, the snap even if it's an old revision or not the expected channel should work on mantic...
