Installing tor in Ubuntu 18 Bionic: "No installation candidate"

Hello can someone please help me with this problem? I tried to create tor.list according to torproject.org, but that did not work (unsigned etc..), so I removed it. I would expect that tor is installed from main ubuntu repository, it is listed in packages...

apt install tor
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package tor is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'tor' has no installation candidate

Solution 1:

Add universe to your sources, and try apt update and apt-cache search tor See what packages are available. i'd try it, but I'm using Android right now. It should tell you the exact name of the tor package.
