Thunderbird disaster upgrade 91 to 102


This worked for me, YMMV

Binaries - sudo mv /usr/lib/thunderbird  /usr/lib/102thunderbird
as normal user, cd /home/user
User Files - mv .thunderbird .102thunderbird

go to the and get the version you want...

sudo tar xjvf thunderbird-91.1.2.tar.bz2 -C /usr/lib         <- the "-C" plus location is the magic bit
ln -s /opt/thunderbird/thunderbird /usr/bin/thunderbird
[sudo] password for one:
ln: creating symbolic link `/usr/bin/thunderbird': File exists
sudo rm /usr/bin/thunderbird
ln -s /opt/thunderbird/thunderbird /usr/bin/thunderbird

Recover your user data from the backup location to ".thunderbird" in home directory
cd /whereever/.thunderbird; tar cvf - . | (cd /home/user/.thunderbird; tar xfBp -)

Apologies for an unnecessay post at a time of high drama.

Any ideas if the linux lite repository permits a re-install of thunderbird 91.x.x, rather than
accepting tbird 102?

No flatpaks, no snaps, just a .deb file.

I have backups of all the user stuff, and I could at a push, got back to the last ISO,
but I would really like to avoid that.....

Many Thanks for reading this far
