Sorry, but this isn't a bug in Mono - there's a problem with your download:
dpkg-deb: `/var/cache/apt/archives/libmono0_2.4+dfsg-5_i386.deb' is not a
debian format archive
Try removing that file, then try the update again

In fact, it's almost as if you ran out of disk space or something

You are almost certainly correct. I cleared a folder of cached debs and
the problem evaporated when aptitude redownloaded them.
Thanks for your help.
