Kubuntu/snap: Thunderbird moved after update / profile and mails gone
Hello, I am using Kubuntu 24.04.2 LTS on a Lenovo T470. After a regular installation of updates via Discover three days ago, thunderbird can no longer be started via the icon in the window bar (message: KDE -Plasma workspace: The file or folder /snap/thunderbird/644/usr/lib/thunderbird/thunderbird-bin does not exist).
I was able to start thunderbird via the menu (the location now appears to be /snap/bin/thunderbird), but the profile and all mails have disappeared, as if I had reinstalled thunderbird.
The Personal folder/snap/thunderbird folder contains the folders 721, 734, common and current. Only common has something, but very little content (25 MB).
I set up my profile again in the post-update thunderbird (no problem thanks to imap-server), which works well. However, now I have two icons: If I click icon no 1, thunderbird starts as a new installation without any profile and mails, icon 2, thunderbird starts with my profile.
Can anyone make sense of this strange behavior?
