A new spotify update was pushed to the stable channel today (version 1.2.8.923.g4f94bf0d) but the update appears to be failing with the following error:
- Setup snap "spotify" (63) security profiles (cannot update mount namespace of snap "spotify": cannot update preserved namespace of snap "spotify": cannot update snap namespace: remove /usr/bin/gjs: read-only file system)
The failed update left the snap in a broken state with the following error when trying to launch the app: ERROR: not connected to the gnome-3-28-1804 content interface.
A workaround is to remove the spotify snap and then do a fresh installation of the latest version, although this means that you will have to log in again and re-apply settings.
Instead of re-installing you should just use the snap revert command to go back to the former version on disk. (assuming the next revision will have a fix, it will automatically upgrade to it then)
Interestingly the update failed on 2 machines and succeeded on a third machine. The machines where the update failed remained on the version number before the update (so there was nothing to revert back to), but the connection to the content interface (and perhaps other interfaces) was lost during the upgrade process and wasn’t restored when the refresh failed.
I can confirm this, the same happened to me when trying to update spotify using snap refresh. Removing & installing it again solved the problem (but I needed to log in again).
