Thank you thanos1983 for sharing the link. The solution there worked for me as well.

patchperl was missing from ~/perl5/perlbrew/bin/

So I did:

curl https://raw.githubusercontent.com/gugod/patchperl-packing/master/patchperl > ~/perl5/perlbrew/bin/patchperl

And then

[~]$ perlbrew install perl-5.28.1

This time it worked and installed perl-5.28.1.

Somehow `perlbrew available` still doesn't work but that's not a big deal for me. I'll know the version number that is available and if I want to install it or not.

[~]$ perlbrew available

ERROR: Unable to retrieve the list of perls.

[~]$
