Thunderbird got downgraded via Flatpak - best next steps?

more options

I'm using Discover to update Flatpak apps. A few days ago it updated to the latest 128 version of Thunderbird and I had subsequently made some changes to my profile and the details.

I wasn't paying attention this morning when updating via Discover and, once finished, found that Thunderbird had been downgraded to 115, leaving me unable to open it without the "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version." message.

I don't want to create a new profile, so what's the best way for me to switch back to 128 while maintaining the profile I had set up on it?

I wasn't paying attention this morning when updating via Discover and, once finished, found that Thunderbird had been ''downgraded'' to 115, leaving me unable to open it without the "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version." message. I don't want to create a new profile, so what's the best way for me to switch back to 128 while maintaining the profile I had set up on it?

I just had the same issue!

I downgraded Thunderbird using the following commands. The mask command is needed so it wont be auto-updated by Discover or Gnome Software

sudo flatpak update --commit=2151b1e101f1266d135040c142f4c36a7e3373dc772e75a509a38efc39ded993 org.mozilla.Thunderbird flatpak mask org.mozilla.Thunderbird

It looks like you're referencing Windows @lampros. This is for flatpak on Linux.

Is there a way for you to start in terminal Thunderbird executable by adding the commands -p --allow-downgrade

i.e. Thunderbird(executable) -p --allow-downgrade

Hey presto, TB opens, fixed. Can't wait for a replacement for TB to turn up, I hate having no alternatives (with local folder abilities)

This bug is now fixed and you should see a refreshed version in Flatpak.
