I'm new on the forum and so i give my best regards to all the users and admin
I'm using Linux Mint for 2/3 years and it was working well...i have the Sonya release 18.2...after an upgrade i had this problem from 1 month during i tried to find the resolution googling etc but no one worked for me...when i do a simply un upgrade (not dist-upgrade) the software is ugraded but from the security repository i have this message:"The repository 'http://archive.ubuntu.com sonya-security Release' does not have a Release file.Data from such a repository can't be authenticated and is therefore potentially dangerous to use.See apt-secure(8) manpage for repository creation and user configuration details. It's imposible to find http://archive.ubuntu.com/dists/sonya-s ... 4/Packages 404 Not Found [IP: 22.214.171.124 80] It's impossible to download some index files: they will be ignored or will be used older ones.
