I have been unable to run apt get update command properly due to many errors that seem to suggest some repositories are unavailable. I tried 'apt-get clean' but it did not help. I have the following message (Ubuntu 18.04)

Err:13 http://uk.archive.ubuntu.com/ubuntu bionic amd64 Contents (deb)

    Does this answer your question? What can I do if a repository/PPA does not have a Release file? – Artur Meinild Mar 22 '21 at 11:14
  • eoan or 19.10 is EOL and after releases go EOL, many repositories are deleted. if you check your eoan source you'll note they only provide packages for supported releases (your eoan isn't supported) – guiverc Mar 22 '21 at 11:23
  • Excuse my lack of linux knowledge... I tried 'sudo ppa-purge https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/', but i get an error on this command - E: The repository 'https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/ Release' no longer has a Release file.
