Debian repository & apt problems

Question

I'm on fresh Debian 10 install.

When I try to install openvpn with apt, it shows package not found.

Running apt update changes nothing.

As I think openvpn must surely be in repo I realise that there must be some problems in my sources.list.

My sources file contains this:

deb http://security.debian.org/debian-security buster/updates main contrib
deb-src http://security.debian.org/debian-security buster/updates main contrib

deb http://deb.debian.org/debian/ buster-updates main contrib
deb-src http://deb.debian.org/debian/ buster-updates main contrib

What's wrong?

Answer 1

The main repository is missing in your sources.list. To add it with the contrib repository, add these two lines (binary and source packages) to your sources.list:

deb http://deb.debian.org/debian buster main contrib
deb-src http://deb.debian.org/debian buster main contrib

Then run

sudo apt-get update
sudo apt-get install openvpn
