Thanks for your answer, Sebastien. I think you nailed it. There was not enough free space to copy the profile and the profile was not copied. I had tried to softlink my old profile from .thunderbird info snap/thunderbird/common/.thunderbird but that did not work, as I described, and it still doesn't.
However, moving the thunderbird profile instead of softlinking did solve the problem. The maybe a problem, though, since some people like myself have massive profiles with years of emails, and users are warned about the root space they need for the upgrade, but not the space in the home directory. Specially if several users share the computer.
