It is not unusual to have problems with these packages on new OS installs because they tend to rely on older libraries (gfortran is the most common example) which the developers have carried over from an earlier OS release, but aren't installed by default in fresh OS installs. I generally do upgrades a couple times, then a fresh install to try a new filesystem (xfs a while ago, and recently btrfs) and because linux accumulates old libraries over time. This has resulted in cases where my system was able to run 3rd party packages that required older libraries and would not run on colleagues systems with fresh install. If time permits, I do update before the fresh install to check for issues in mission critical apps. The issues I have seen: On an elderly system with an old Nvidia card, the new kernel had a bug in nouveau affecting my card. I had to use an older kernel until the bug was fixed. With other distros and the same machine I have had issues when drivers were removed from the kernel (they were eventually restored). On newer hardware with UEFI, upgrading from F34 to F35 failed to boot. I used the rescue kernel to discover that the kernel command line generated by the installer had misplaced quotes adding back "rhgb quiet" that I had removed. Since I was planning a fresh install anyway, I didn't try very hard to fix the problem, just did a fresh install with a new filesystem. -- George N. White III
