I've been doing some setups using openSUSE Leap 15.6 recently for $work. Here are the zypper packages I used to get the cpan utility running cleanly (you may not need all of these).

Checking my old notes, this worked the same for openSUSE Leap 15.4. Presumably also good for Leap 15.5; and possibly for (some) versions prior to Leap 15.4.

Here's the perl & cpan info (cf. Re^2: cpan: Terminal does not support AddHistory. posted earlier): 

kenc@vdesktop35 ~/tmp
$ perl -v | head -2 | tail -1
This is perl 5, version 26, subversion 1 (v5.26.1) built for x86_64-li
+nux-thread-multi

kenc@vdesktop35 ~/tmp
$ cpan

cpan shell -- CPAN exploration and modules installation (v2.38)
Enter 'h' for help.

cpan[1]> o conf pushy_https
    pushy_https        [0]
Type 'o conf' to view all configuration items


cpan[2]> o conf urllist
    urllist

cpan[3]> q
