Hello! Today i decided to install ElementaryOS and installation was fine but after installation i get weird popups (failed to fetch) and in console i get messages like this : Code (Text): W: The repository 'http://security.debian.org/debian-security loki Release' does not have a Release file.

Seems like you are not connecting to the repository on the current server you have selected. Try changing servers and then run the below should fix it. Code (Text): sudo apt-get autoclean sudo apt-get clean sudo apt-get update
