I tried to reproduce this inside a VMware instance and was unable. I tried using
the DVD in text mode and just using the defaults for all the screens. I tried do
a custom package selection. I didn't see the error.

I got this. Trying to upgrade FC5 to FC6. GUI install hangs when checking
dependencies. No errormsg seen. Text mode installer hangs in dependency checking
saying that:

No handlers could be found for logger "yum.YumBase"

Please trace this and give us some workaround to upgrade.

I have AMD Athlon 1300 MHz, 1 GB RAM, 2 x IBM IDE 60 GB configured as software
RAID1 mirror set. Booting installer from ATAPI CD-ROM drive with install CD #1 of 5.

Actually saw some ERROR or WARNING about /var/lib/rpm/__db* files in some
virtual console when installer hanged. My current FC5 installation has those
files there on the hdd. So, is it widely recommended to

rm -f /var/lib/rpm/__db*

rpm --rebuilddb

..before upgrading? Is there any problems comening if doing that task before
giving the upgrade a new try?

My FC5 is fully patched. Yum and standalone rpm works fine there. I know there's
been those problems in rpm which sometimes requires you to 'rpm --rebuilddb'
manually, but I believe that the rpm of FC5 would be fixed for this already. I
guess RH8 and RH9 had these problems with old rpm versions.

Tried rm -f /var/lib/rpm/__db* and rpm --rebuilddb and it still hung up. I am
going to let it sit for about an hour and see what happens.

I let it sit for about 45 minutes and the update continued as normal. 

Same here. It took more than 30 minutes to check the dependencies. After that
the upgrade succeeded, even the total time spent was longer than ever. After any
CD change there was a bit shorter wait time.

This seems to be fixed in Fedora 7 - should we closed it as NEXTRELEASE ?

Hello,

As said in comments #8 and #9, this was fixed in Fedora 7. IMHO, this bug may be
closed.

I would close it, but I'm not an authorised user.
