apt update error message “Could not execute ‘apt-key’ to verify signature”

It turned out the reason for this was changed permissions on the /tmp folder (caused by restoring a folder with BackupPC to /tmp instead of it’s original location).

Solution:

chown root:root /tmp
chmod 1777 /tmp

After this apt update worked as normal.
