These were similar issues: legacy/trac#12994 (moved) #27445 (closed)
Also, I am not sure if the deb.torproject.org-keyring
package will help after the expiry if the key is added using the newer method described on https://support.torproject.org/apt/tor-deb-repo/ (tpo/web/support#138 (closed)). Do you know?
