Thunderbird 115 Supernova on Ubuntu: anyone else got the "Couldn't load XPCOM" error? (lemmy.sdf.org)

I'm on Ubuntu 20.02, and have the older 102 version of Thunderbird installed from the http://ppa.launchpad.net/mozillateam/ppa/ubuntu ppa.

I wanted to install the new "supernova" – but not from snap or flatpack – so I downloaded the linux tarball from https://www.thunderbird.net/en-GB/thunderbird/all/ and followed the installation instructions.

As far as I can see I have all required libraries, but when I launch thunderbird it complains that

XPCOMGlueLoad error for file /opt/thunderbird/libxul.so:
libXtst.so.6: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

I can't find any libXtst on apt, but I do have the latest libxtst6. So I don't understand the problem.

Anyone else has this problem and maybe a solution? Cheers!

Edit: I see that it's available on the beta ppa, but that's only for Ubuntu 22.02+. Probably I just have to wait until it's available in the stable ppa too...
