Installing PostgreSQL 16 on Rocky Linux 9: the Perl::IPC::Run problem
Today I was preparing a new machine, based on Rocky Linux 9, for some development activity. I was installing PostgreSQL 16 and the development stuff I need, so I was executing (after having imported the PGDG repository), the usual:% sudo dnf install postgresql16.x86_64 \
postgresql16-contrib.x86_64 \
postgresql16-devel.x86_64 \
postgresql16-libs.x86_64 \
postgresql16-plperl.x86_64 \
postgresql16-server.x86_64
...
Error:
Problem: cannot install the best candidate for the job
- nothing provides perl(IPC::Run) needed by postgresql16-devel-16.1-2PGDG.rhel9.x86_64 from pgdg16
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Apparently I’m not able to find out a
Perl-IPC-Run module on the Rocky Linux repositories, nor in the epel_release ones.
The correct way is to enable the crb repository:
% sudo dnf config-manager --set-enabled crb
And that’s it:
% dnf search Perl-IPC-Run
==================================== Name Matched: Perl-IPC-Run ====================================
perl-IPC-Run.noarch : Perl module for interacting with child processes
perl-IPC-Run3.noarch : Run a subprocess in batch mode
Another approach is to install it the Perl way! I prefer to use
cpanm as Perl package manager nowdays, but cpan and others work equally well:
% sudo dnf install perl-App-cpanminus.noarch
% sudo cpanm IPC::Run
