Issue Upgrading to PMS 1.43.0.10467 on Debian and RHEL based distributions

Plex Media Server
1

Updated: February 14th 2026

Yesterday we released Plex Media Server 1.43.0.10467 to production and saw reports of issues with package signatures. We are in the process of rolling back that release while we debug this issue. The current production version will be 1.42.2.10156 once that roll back is complete.

Some background: we are currently migrating to a new build system for PMS. That migration has taken longer than we initially anticipated and introduced some additional complications with regard to how these packages are signed for Debian and Redhat (RHEL) linux distributions.

The recent release attempted to make this upgrade seamless for PMS users on these linux distributions but there was a problem that caused most package managers to find issues with the Plex debian and rpm repositories. We apologize for this inconvenience.

For instructions on fixing this issue and setting up the new repositories please see https://support.plex.tv/articles/235974187-enable-repository-updating-for-supported-linux-server-distributions/

Pretty sure your markup of the debian source is wrong

4

So there is no impact to non-Linux servers ?

For example a Windows based server, of which mine is one, that auto updated,

5

no impact to pms servers at all, the impact was to linux package managers. unfortunately we do not have the setup to only pull some distributions but not others.

Thanks for the reply and sorry for my ignorance.

Error: Malformed entry 1 in list file /etc/apt/sources.list.d/plexmediaserver.list ([option] not assignment)

I edited the markdown, can you guys try again?

12

Your markdown is still bad you don’t need the hyperlink syntax, should look like this.

13

As an FYI (which you probably know already but said I’d mention it) doing a manual local install outside of the repo doesn’t have any issues. I’m on fedora 43 …

sudo dnf install /data/Personal/Software/fedora/plexmediaserver-1.43.0.10467-2b1ba6e69.x86_64.rpm

14

yea, i found that. It was a copy paste error

15

Works now but I am getting Err:4 https://downloads.plex.tv/repo/deb public InRelease

The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 97203C7B3ADCA79D

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used.

I am checking on this

17

Do we need to do something if we have upgraded (win 11) or we are good to go until the next update? All is working btw

18

Now I’m back to this:
Warning: https://downloads.plex.tv/repo/deb/dists/public/InRelease: Policy will reject signature within a year, see
–audit for details

19

Does this affect official docker plex installations?

I don’t think you provided the key for signed-by=/usr/share/keyrings/plexmediaserver.gpg
