[SOLVED] Yum dependency I'm trying to install doesn't have a provider

Issue

One of the dependencies of the rlwrap package I'm trying to install doesn't have a provider. Is there a command line option I can pass to the install to let it forget about the perl(File::Slurp) dependency?

I have installed the perl(File::Slurp) dependency separately. For reference, this is the command I am using to install the rlwrap package and error:

yum install rlwrap
Last metadata expiration check: 0:41:10 ago on Thu Dec 22 16:38:35 2022.
Error: 
 Problem: cannot install the best candidate for the job
  - nothing provides perl(File::Slurp) needed by rlwrap-0.45.2-2.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I have tried the suggestions from the yum output.

Solution

I was wrong about EPEL having all the dependencies. It looks like perl-File-Slurp lives in the "AppStream" repository. You can add the the CentOS 8 version of that repository to your ubi8 image:

1. Install dnf if you haven't already:

   microdnf install dnf
   

2. Add the repository configuration (note that I have this disabled by default):

   cat > /etc/yum.repos.d/centos-appstream.repo <<'EOF'
   [appstream]
   name=CentOS Stream $releasever - AppStream
   mirrorlist=http://mirrorlist.centos.org/?release=$releasever-stream&arch=$basearch&repo=AppStream&infra=$infra
   gpgcheck=1
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
   EOF
   

3. Install the CentOS 8 GPG key:

   rpm --import  https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
   

4. Enable the EPEL repository if you haven't already:

   dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
   

5. Install rlwrap:

   dnf --enablerepo=appstream install rlwrap
   

---

Alternately, instead of installing rlwrap and it's myriad dependencies, just install socat:

microdnf install socat

And then use the readline and exec connectors:

socat readline exec:"/path/to/some/program --arg foo",pty
