in thread [SOLVED]: perlbrew/curl: curl: (60) Peer certificate cannot be authenticated with known CA certificates

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.

[~]$

    Sounds like there was a variable not set as you had to install patchperl manually. If I were in your spot, I would run the upgrade procedure to see if I could get 

     
perlbrew available

    [download]

    working. I would also see if I could get 

    perlbrew list

    [download]

    to work as well. If they still didn't work, then I would concede and finally get the Admin to look at the problem.

      perlbrew list does show installed version (I was also able to switch to this latest version)

      [~]$ perlbrew list
 * perl-5.28.1
[~]$

      But perlbrew self-upgrade or perlbrew install-cpanm are failing. This concerns me and I think I'll have to get an Admin to help me.

      [~]$ perlbrew self-upgrade
Unable to detect version of new perlbrew!
[~]$ perlbrew install-cpanm

ERROR: Failed to retrieve cpanm executable.

        One last shot at trying to save the Admin time. I would run: 

        $ cd App-perlbrew
$ git pull
$ perlbrew self-install
$ perlbrew init

        [download]

        Then, I would re-run the perlbrew available commands.

        If THAT did not work, I would suspect a problem higher up in the trusted computing base -- one that I did not have appropriate permissions to solve.
