Hi everyone,

The following error has started to appear while fetching updates in KDE Discover:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://ctan.fisiquimicamente.com/sy...ktex/setup/deb noble InRelease: The following signatures were invalid: EXPKEYSIG 277A7293F59E4889 MiKTeX Packager <packager@miktex.org>
E: https://ctan.fisiquimicamente.com/sy...ktex/setup/deb noble InRelease is not (yet) available (The following signatures were invalid: EXPKEYSIG 277A7293F59E4889 MiKTeX Packager <packager@miktex.org>)

How do I solve it?

Thanks in advance

Contact the people responsible for the third-party repo you added?

The url for the miktex repo you have here is not the one that miktex uses though it well could be a mirror.

The command:

sudo apt-key del "F59E4889"

worked fine and then I just had to register the CPG key following the instructions available on the MiKTeX website (link, Linux section).
