Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

# A bit about libraries
---
## System libraries
These are shared common components that are used by a variety of software on a linux system. For the most part they are a collection of compiled code (typically C / C++) that are stored in a single file.
* Allows for code reuse
* Allows for multiple (concurrent) versions
* Avoids reinventing the wheel
* Installed in `/lib`, `/usr/lib`, `/usr/local/lib`, etc.
* Two flavors: static (`.a`) and dynamic (`.so`)

## Getting what you want
The following is my understanding of the general system library package naming schemes for these distro families, there will definitely be exceptions and edge cases.
These are the names that would then be used with something like `apt install` or `yum install` respectively.
| | Debian | Redhat |
|-----------------------|-----------------|-----------------|
| Dynamic library (.so) | `lib{name}` | `{name}` |
| Headers | `lib{name}-dev` | `{name}-devel` |
| Static library (.a) | `lib{name}-dev` | `{name}-static` |
| Documentation | `lib{name}-doc` | `{name}-devel` |
