Lightning doesn't work in Thunderbird 60+
Running Tails 3.9.1, installing the
lightning package will pull our
1:60.0-3~deb9u1.0tails2 build. Thunderbird then lists Lightning as enabled in the Add-on manager, but none of the calendar functionality works or is visible (e.g. the "Events and Tasks" menu is not present) so it is just as if Lightning is disabled.
Installing Debian stretch's versions
lightning fixes the problem. Actually, after this it seems like the profile has been fixed for this problem; if installing our versions, then Lightning suddenly works as it should! So the following is a workaround that permanently fixes persistent Thunderbird profiles:
echo "deb tor+http://vwakviie2ienjx6t.onion/debian/ stretch-proposed-updates main contrib" >> /etc/apt/sources.list apt update apt install thunderbird=1:60.0-3~deb9u1 lightning=1:60.0-3~deb9u1 # Now start Thunderbird and verify that Lightning works. Don't do anything else! apt install thunderbird=1:60.0-3~deb9u1.0tails2 lightning=1:60.0-3~deb9u1.0tails2
So, what is wrong with our builds compared to Debian stretch's? With #16019#note-8 we established that there in practice shouldn't be any difference, but apparently there is.
Also, intrigeri said this, which might be relevant: "IIRC lightning is treated in a particular way wrt. extension scopes. might be worth playing with extensions.autoDisableScopes and extensions.enabledScopes if it's not enabled."

Relevant error message: "lightning : Depends: thunderbird (>= 1:60.6.1-1~deb9u1) but it is not going to be installed".
So we have two problems here:
- We should pin the
lightning*packages just like we pin the
thunderbirdones. Otherwise, we're creating an inconsistent APT config that's bound to create coinstallability issues such as this one.
- Whether our own current lightning package works or not is unclear. It might still be broken as described by anonym earlier on this ticket. It might be fixed. I say let's fix the co-installability issue first and then we'll see.
For now I'm not treating this as core work as we don't install Lightning by default.
