Why do dependency errors occur in linux?

Question

linux

Good afternoon!
I put a completely empty alt linux 7 on my VPS. Initially, I couldn't install anything because apt-get didn't see any packages. After I did sudo vim /etc/apt/sources.listand added two lines:

rpm http://ftp.altlinux.org/pub/distributions/ALTLinux/t6/branch i586 classic
rpm http://ftp.altlinux.org/pub/distributions/ALTLinux/t6/branch noarch classic

After I did apt-get update, everything is ok. For the sample, I decided to install nano. In response to apt-get install nano , I got this . How can this be fixed and what is causing it?

Answer 1

You have altlinux 7, but you use the repository from the sixth.
ftp.altlinux.org/pub/distributions/ALTLinux/t7
