GPG error for APT when accessing Google repositories #2094
Description
Hello
Recently (July 2022) 2020Sanoj and MrBenGriffin have reported that this issue has resurfaced. I can report that I too am seeing it on Ubuntu 20. The original issue was "GPG error: https://dl.google.com/linux/mod-pagespeed/deb stable Release: The following signatures were invalid #1979".
Here's the output when I try to run apt-get update ...
Err:8 http://dl.google.com/linux/mod-pagespeed/deb stable Release.gpg The following signatures were invalid: EXPKEYSIG 78BD65473CB3BD13 Google Inc. (Linux Packages Signing Authority) <[email protected]> Reading package lists... Done W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://dl.google.com/linux/mod-pagespeed/deb stable Release: The following signatures were invalid: EXPKEYSIG 78BD65473CB3BD13 Google Inc. (Linux Packages Signing Authority) <[email protected]> W: Failed to fetch http://dl.google.com/linux/mod-pagespeed/deb/dists/stable/Release.gpg The following signatures were invalid: EXPKEYSIG 78BD65473CB3BD13 Google Inc. (Linux Packages Signing Authority) <[email protected]> W: Some index files failed to download. They have been ignored, or old ones used instead.
My APT repository simply has ...
deb http://dl.google.com/linux/mod-pagespeed/deb/ stable main
And I have added the APT key https://dl.google.com/linux/linux_signing_key.pub mentioned here https://www.google.com/linuxrepositories/. The fingerprints displayed when I run apt-key list are the same ones referenced in the documentation.
