My parents have had the same experience, and I did the entire upgrade
via SSH from across the country (combined backend/frontend and two
standalone frontends).

Ubuntu's mythdatabase package has an issue with it's post-install
script which requires manual tweaking of placing your database login
info in and then as far as I can tell fixing the access permissions
for remote frontends.

Sadly, it also sounds like the bug with recordings interrupting LiveTV
still isn't fixed, hopefully one of the dev's takes a serious look at
this issue soon.

I'm looking forward to the MythMusic changes, hopefully it will make
it usable for me. I just need to find a day to upgrade all my
systems...
