== An important lesson for me on Fedora upgrades

As I mentioned in a [[recent entry ConsideringFedora12]], Flash has
been broken for me for all of Fedora 11 on my 64-bit machine. The
comments on my entry caused me to dig into the situation, and after
some experimentation (building a fresh installed 64-bit Fedora 11 in
a virtual machine to see if Flash worked, which it did), I found my
problem and now have working Flash.

In fact, I found the problem doing what I should have done in the first
place; I ran '_package-cleanup --problems_', which reported that I
had a libflashsupport RPM (in both 64-bit and 32-bit versions) that
had unmet dependencies on specific versions of libcrypto.so.6 and
libssl.so.6. Removing the libflashsupport RPMs unsurprisingly made Flash
work again.

(libflashsupport seems to come from Fedora 8. _package-cleanup_
comes from _yum-utils_, which I think everyone should have installed.)

I think it's time that I ran all of _package-cleanup_'s tests to make
sure my machine is relatively clean. In fact, I should make a habit of
doing this after every Fedora upgrade that I do, because upgrading can
easily leave you with exactly this sort of problems.

(Note that not all of what _package-cleanup_ complains about is
a genuine problem, especially for its _--orphans_ option.)
