I recently updated my server to OMV 5 and upon trying to reinstall TVHeadend, noticed that installation, on ARM devices running Buster, was a bit different and ended up on this page for the installation:
I successfully installed 4.3-1857~g221c29b40 and it has been fine, but for a major issue - OTA EPG grabbing will not refresh properly.
The only way to get new data is to restart the server.
I am trying to find a newer version of TVH 4.3 and noticed on this page:
that there is an unofficial Michale Marley PPA, offering newer builds.
I tried to add the unstable version but am getting the following error:
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 26F4EF8440618B66W: GPG error: http://ppa.launchpad.net/mamarley/tvheadend-git/ubuntu groovy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 26F4EF8440618B66E: The repository 'http://ppa.launchpad.net/mamarley/tvheadend-git/ubuntu groovy InRelease' is not signed.
I would be really grateful for some advice on what to do, next.
