profiles making a run for it

[Sergio Schvezov]

On certain boots, `corebird` just stops working, the profiles seems to magically vanish. A simple `disable` followed by an `enable` is enough to bring the profile back.

Does this happen on 2.32.5 (which is available in beta). It has a number of fixes, some of those related to system key and profiles. Were you, by any chance, restarting to different kernels?

[Oliver Grawert (ogra)]

i had the same issue with a sideloaded snap that works fine on an identical desktop install but on the laptop installation it showed:

ogra@acheron:~$ snapcraft-forum
cannot change profile for the next exec call: No such file or directory
snap-update-ns failed with code 1: No such file or directory
ogra@acheron:~$ snap run snapcraft-forum
cannot change profile for the next exec call: No such file or directory
snap-update-ns failed with code 1: No such file or directory

refreshing core to beta got me out of this state ...

[Zygmunt Krynicki (zyga)]

We have identified this issue and will release a fix as snapd 2.32.6

For those curious in the technical details of the problem please look at https://github.com/snapcore/snapd/pull/5109

[Zygmunt Krynicki (zyga)]

The fix for this issue is now available in the beta channel (as snapd 2.32.6)

To everyone affected: please help testing by refreshing your core snap to the beta channel with "snap refresh core --beta". If your distribution does not support snapd re-execution this operation will not update your snapd (you can confirm that with "snap version") and thus you will need to wait for a release specific to your distribution.

This was released to stable as snapd 2.32.6
