After more than a year of troublefree updating my TVH installation, I find that now when I execute a 'sudo apt update' I get the following error:
W: Skipping acquire of configured file 'main/source/Sources' as repository 'https://apt.tvheadend.org/stable bionic InRelease' does not seem to provide it (sources.list entry misspelt?)
Here is my /etc/apt/sources.list.d/tvheadend.list:
deb https://apt.tvheadend.org/stable bionic main
deb-src https://apt.tvheadend.org/stable bionic main
My system is an updated (to a month or so ago) Ubuntu 18.04 Bionic headless server.
I have read the TVHeadend Downloadwiki page but I do not see what is wrong.
Could someone point me in the right direction please?
