I assume you are using installJRMC or my repository to install MC on CentOS 8. I recently updated installJRMC to match the dependency versions specified by the JRiver-provided deb (based on Debian Buster). So any distros with libraries older than Buster (like CentOS 8 ) will run into this issue with newer RPMs.

I've been mulling over this problem, but there isn't really a good solution at the moment without manually lowering (or removing) the version dependencies in the build script to fix compatibility with older distros. The tradeoff is unnecessary complexity (creating RPMs per distro, per version) or potentially breaking compatibility with new versions of MC. One possibility I've come up with is adding a "--universal" flag that will create an RPM without any library version restrictions whatsoever, obviously YMMV if it will work or not on your particular distro.

The reason I never implemented this is because CentOS 8 is effectively dead in the water (only 5 days of support left) and the best solution for most users is to migrate ASAP to CentOS Stream 9 or some other flavor of EL9 with newer libraries (and a longer support window).

[BryanC]

I uploaded version 1.0b5 of installJRMC that has a new "--compat" option to build/install RPMs on older distros like CentOS 8.

1. Remove the existing RPM output: rm -rf output/RPMS
2. Run installJRMC with --compat option: ./installJRMC --install rpm --compat

If you have any issues, please rerun and provide output with --debug.

It appears RHEL 8.5 doesn't provide some of the required dependencies.  I'll find and build the "dpkg-deb" and try again soon.

This looks like a different problem related to OS detection. Could you paste the output of `cat /etc/os-release`?

I also just released 1.0b9 here that should provide some more informative output, if not fix the detection. Once CentOS is detected properly it will install the EPEL repo that contains the dpkg package.

[mblakeman]

It's not CentOS it's RHEL.  I don't use the EPEL but I do plan on installing dpkg-deb manually.

[BryanC]

Thanks, I will add RHEL support in the next release.

[BryanC]

I just added RHEL support and improved OS detection in installJRMC 1.0b10. Note that it will install EPEL repo and dpkg + other dependencies by default on CentOS/RHEL as this is the path of least resistance for most users. At some point in the future I will detect if the dependencies are already installed and skip adding the repo.
