Hi @macgrioghair!
Basically, I’ve removed the snap version of Thunderbird embedded in UB 24.04 and what I guess @guiverc calls a stub:
sudo snap remove thunderbird && sudo apt remove thunderbird
As the .deb package is not in the Ubuntu repositories anymore, you must first add the Mozilla Team PPA:
sudo add-apt-repository ppa:mozillateam/ppa
Note that you still need to override the snap format.
So create this file:
sudo gedit /etc/apt/preferences.d/mozillateamppa
Insert the following code and save:
Package: thunderbird*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
After that, this is the .deb version that you are actually going to install:
sudo apt update && sudo apt install thunderbird
It works fine. But the version is obviously different:
apt show thunderbird
Package: thunderbird
Version: 1:115.14.0+build1-0ubuntu0.24.04.1~mt1
Priority: optional
Section: mail
Maintainer: Ubuntu Mozilla Team <ubuntu-mozillateam@lists.ubuntu.com>
