Possible problem w/ freebsd-update

[RJPugh]

Good evening.

I am attempting to upgrade an instillation of 7.2-RELEASE (DesktopBSD 1.7) to 7.3-RELEASE, using the freebsd-update tool. The syntax I'm using is this:

] freebsd-update upgrade -r 7.3-RELEASE

My plan is to work my way up to 8.1-RELEASE, but one step at a time. Anyway, when I invoke the command, it seems to go OK for a while, until I get this sequence of error messages:

{begin error messages}

Fetching files from 7.2-RELEASE for merging... done.
Preparing to download files... [: files/Segmentation: unexpected operator

/usr/sbin/freebsd-update: cannot open tmpfile: No such file or directory

{end}

Can anyone tell me where this segmentation fault is coming from, and what I can do (if anything) to rectify it? I think my current version of freebsd-update, but is there any way I can verify that?

I'm not a rank amateur when it comes to BSD, but I'm far from an expert, so go easy on me.


Thanks in advance,
