Updating to Fedora 13 with preupgrade I faced some issues. The first one, which apparently is not documented, is that while downloading release info, I got an error message telling me that there was a problem with the mirror.
running preupgrade in a terminal, I saw the following error:
checksum failure downloading vmlinuz
There was definitely a problem with the mirror. I tried several times getting the same error, so I decided to ask in #fedora-qa about it.
And this is the fix:
wget http://mirrors.fedoraproject.org/releases.txt
edit releases.txt, comment mirrorlist and uncomment baseurl, setting the URL of the mirror that we choose, or leaving the default URL download.fedora.redhat.com.
Then run preupgrade with releases.txt in our $PWD
Another issue that I had was reported in BZ 573451
I’m stilling updating and I hope it ends successfully.
