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 two 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 can then 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).

Sure, I can/could now simply set up my profile again (no problem thanks to imap-server), but I find this behaviour strange and have to ask myself whether it happens again and again.

Could any of you tell me what’s going on?

Thank you!

Sounds like an issue with the Snap version of Thunderbird.

You probably need to report this at Kubuntu or Ubuntu

And for what it’s worth, some folks have asked this over at Ask Ubuntu, with some success: https://askubuntu.com/questions/1506802/updating-thunderbird-from-apt-to-snap-removed-my-config

(I had to do this myself when I was using Ubuntu :slight_smile: )

Okay, thank you. I can do that, but where exactly?
