I also just started to get GPG update errors when trying to update apt via apt. I can see that there is a workaround in this thread for downloading the latest DEB package, but is it possible to get the key/signature issue fixed?

W: GPG error: https://downloads.plex.tv/repo/deb public Release: The following signatures were invalid: BADSIG 97203C7B3ADCA79D Plex Inc.
E: The repository 'https://downloads.plex.tv/repo/deb public Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
The team injected additional logic to perform the extended verification at the end points. It seems that presenting the files at the API inlet aren’t always enough for the cloud provider (<shrug>) .
Last night I updated, and it worked fine opted not upgrading since many users where using plex last night. To my surprise its not working again this morning.
Trying to update to 1.19.1.2630 on Ubuntu Bionic Beaver (18.04.4 LTS) and getting this error. Tried the manual Sig update listed in This Topic to no avail.:

W: Some index files failed to download. They have been ignored, or old ones used instead.
Note, I just update to version 1.18.9.2578 just last week absolutely fine, after following the instructions to Enable repository updating for supported Linux server distributions. I went to update this morning after seeing the update avail last night (but plex in use) and this morning it is reporting bad sig.
If you were to see the steps performed, it would make perfect sense.
They have to go through all the different sites. Best I can share is: “It doesn’t handle retries gracefully” .
