I'm kindly asking for your help. I'm trying to update with sudo apt update on Ubuntu 20.04, but I get this error message: E: The repository 'https://download.mono-project.com/repo/ubuntu stable-focal/snapshots/2.6.3 Release' does not have a Release file. I find this command, ls /etc/apt/sources.list.d and I run it. I found two things related to mono in /etc/apt/sources.list.d:

  • mono-official-stable.list
  • mono-official-stable.list.save

I tried to run sudo add-apt-repository --remove mono-official-stable.list but it did not work, When I try to update, the same error appears again: E: The repository 'https://download.mono-project.com/repo/ubuntu stable-focal/snapshots/2.6.3 Release' does not have a Release file. How can I deal with this issue and be able to update repos without getting that error. Thanks in advance for any help.
