Apt update fails with bionic release no longer has a release file (Mariadb)

David Patterson asked:

Tried to update the apt cache with sudo apt update and it failed with:

The repository ‘http://mirror1.imageworld.fi/pub/mariadb/repo/10.4/ubuntu bionic Release’ no longer has a Release file


  • Ubuntu 18.04.4 LTS
  • MariaDB 10.4.12

How do I get around this?


My answer:

That URL does not contain a valid MariaDB mirror. It appears to return 404 for pretty much everything except the host’s homepage.

Go back to MariaDB’s web site and select a valid mirror.
