I have been complaining a lot about seeing an old version of Thunderbird in green, but I am told I should see a later version of 60. Maybe I have a problem of which I am unaware, though other things seem to be updating fine.
Can one person do me the favor of checking the version of Thunderbird by running:
sudo apt update sudo apt list thunderbird
thunderbird/green 1:52.9.1-1 amd64
