Subject:   Issue upgrading to 7.4, looking for guidance
Message-ID:  <>

I recently was having problems with Firefox crashing, which appear to be
related to a requirement for semaphore support for Firefox after the
upgrade to the new version of GTK.

Anyway, this left me with a 7.4 kernel and a 7.2 world. Which I
understand is supposed to work.

However, this broke CUPS for printing, and I need to be able to print to
pdf. This error is generated if I try to build cups, or when cups tries
to load on startup:
/libexec/ ./mantohtml: invalid PT_PHDR

>From looking around on-line, it looks like somewhere between 7.2 and 7.4
there was an incompatibility that causes this error in a number of places
(printing, samba, etc.)

So, it looks like I need to upgrade the rest of the way. But I can't get
the upgrade to work. I thought this was where to start:

# freebsd-update -r 7.4-RELEASE upgrade
Looking up mirrors... 4 mirrors found.
Fetching public key from failed.
Fetching public key from failed.
Fetching public key from failed.
Fetching public key from failed.
No mirrors remaining, giving up.

So I ran uname -a to find that this is 7.4-PRERELEASE

20 19:39:15 MST 2011

so I tried this:

# freebsd-update -r 7.4-PRERELEASE upgrade
freebsd-update: Cannot upgrade from 7.4-PRERELEASE to itself

so, um, what do I need to do to address this error:
/libexec/ ./mantohtml: invalid PT_PHDR
