Problem with Perl and cPanel Update (perl is needed by...)

[mattin]

Hello all,

I have a crucial problem with perl on my cPanel (11.36.0) server. I have moved to amazon so I want to use S3 storage as mounted drive, because of f3s need Perl with multithreaded enabled I build my own perl binaries on centos from perl.org with multithreading. I know that cPanel from 11.36 using its own perl so I thought it will not be a problem. But it completely broke my cPanel... Now I have cPanel partially fixed. I removed all perl binaries (/usr/local/bin/perl and also ln /usr/bin/perl). I added ln -s for perl in bin's pointing to /usr/local/cPanel/3rdparty/perl/514/bin/perl and also added PATH for the same dir.

It looks like now cPanel is fully working, but when I want to do upgrade or force reinstall of cPanel (its same for WHM upgrade, scripts/upcp or updatenow.static) I get dependency error with perl.

I would suggest shooting in a support ticket at https://tickets.cpanel.net. This is not an everyday problem as you can imagine.

Please don't symlink system perl to cPanel perl. If you remove the perl excludes from /etc/yum.conf and run

 /usr/local/cpanel/scripts/check_cpanel_rpms --fix

It should take care of the problem

Oh that mighty cpanel scripts . I don't have it on my server, but i downloaded whole scripts directory from another cpanel server with same version, run it. And it works like a charm! Update was done without problems. I removed symlinks and reinstall system perl. Looks like everything is working. Thank you!
