Outdated APT key for deb.torproject.org

Since a few days, some automated tests fail with:

W: GPG error: tor+http://deb.torproject.org/torproject.org buster InRelease: The following signatures were invalid: EXPKEYSIG 74A941BA219EC810 deb.torproject.org archive signing key
E: The repository 'tor+http://deb.torproject.org/torproject.org buster InRelease' is not signed.

Workaround

This might work:

curl http://sdscoq7snqtznauu.onion/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc | sudo apt-key add - && systemctl --user restart tails-additional-software-install.service
