How can I fix this?

Here is an output of /etc/apt/sources.list :

  • @mook765 FYI i already tried this and it doesnt work for me. Running sudo ppa-purge ppa:ondrej/mysql-5.6 says Updating packages lists E: The repository 'http://ppa.launchpad.net/ondrej/mysql-5.6/ubuntu bionic Release' does not have a Release file. – StormTrooper May 07 '20 at 17:00
  • There is more than one answer in the given link. The other answers are also valid. – mook765 May 07 '20 at 17:02
  • @mook765 I do not post threads usually, but as I have tried so many things strangely doesn't work in the case. Tried this way as well: sudo add-apt-repository --remove ppa:ondrej/mysql-5.6. – StormTrooper May 07 '20 at 17:07

    So did you run sudo apt uipdate then? You can also look for the file /etc/apt/sources.list and comment out the corresponding line with prepending a # or a file in /etc/apt/sources.list.d which can simply be removed. – mook765 May 07 '20 at 17:14
  • @mook765 Yes I did ran sudo apt update but still get same error. Please check output of /etc/apt/sources.list in my question – StormTrooper May 07 '20 at 17:24
  • You have one repo for trusty in this file, the third last line, comment out this line. Regarding the PPA check for files in the directory /etc/apt/sources.list.d and remove the corresponding file. – mook765 May 07 '20 at 17:33
  • @mook765 commented this line: #deb http://archive.ubuntu.com/ubuntu trusty universe and ran sudo apt update. Getting same error – StormTrooper May 07 '20 at 18:08
  • @mook765 deleting ppa:ondrej/mysql-5.6 in /etc/apt/sources.list.d worked for me. Thanks. Much appreciated. – StormTrooper May 07 '20 at 21:29
