Tvheadend

I tried to open Bug ID 6180 with this same issue, and the response was that this was duplicate and marked as invalid. But, I couldn't find this bug, so I'm reopening. Any instructions to update to latest version, from 2009, keeping all settings, networks, muxes, channels, etc. is also appreciated!

Hi,

I'm unable to update from 2009 version, because of the following errors in apt-get upgrade command:

Err:1 http://apt.tvheadend.org/unstable focal/main amd64 tvheadend amd64 4.3-2010~g3b1d7a928~focal
404 Not Found [IP: 104.21.22.193 80]
E: Failed to fetch http://apt.tvheadend.org/unstable/artifacts/9b/2a1nry0i/tvheadend_4.3-2010~g3b1d7a928~focal_amd64.deb 404 Not Found [IP: 104.21.22.193 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

My /etc/apt/sources.list.d/tvheadend.list file is:
deb [arch=amd64] http://apt.tvheadend.org/unstable focal main

It seems that files are missing in the repo. Anyone with the same issue?

Thank you.
