| I have a fresh installation of FC6,
I should have mentioned that my installation of FC6 was from scratch,
not an upgrade. Apparently an upgrade is the root of much evil.
| and decided what the hell, may as well try
| a global upgrade and see what happens
I have done updates fairly often over all the years of Fedora and many
of Red Hat Linux. Mostly they have worked. Only a very few problems.
| First of all, what is the "-t" switch to yum? I know "-y" tells yum to answer
| "yes" to everything, but I can't find "-t" in the man page. But, I digress...
I'm an old-school UNIX guy (using it regularly since 1975) and I
really miss the definitive man pages.
"yum --help" says:
-t, --tolerant be tolerant of errors
| Anyway, I tried a global yum upgrade of everything in my fresh FC6
| installation, and after several hours, it hung pretty much the same as yours
| did.
Unfortunately my hang and yours give very few clues about what went
wrong. No (visible) panic message, no error messages. So they could
be symptoms very different problems.
| I rebooted, and cannot get the new kernel (2.6.20) to boot... gives me
| kernel errors.
That's sad. What errors?
| My problem for the future, though, is I have absolutely NO idea how to revert
| to a previous installation and remove the effects of a failed "yum -yt
| upgrade".
We don't know what failed. We do know that there was a crash in the
middle of a yum upgrade. It would be really nice if yum treated the
system like a database with ACID properties: upgrades would always be
left in a consistent state.
/var/log/yum.log might be useful but who knows if it is complete when
the run is interrupted by a system crash.
| Otherwise, I don't dare upgrade or update much of anything, which for many
| reasons is not good policy...
As I said, I've had mostly good luck with updates. I don't trust my
internet connection so I download the updates repo and use the local copy.
