For documentation purposes and web searches. Not FC7 yet, but applicable. Ran an upgrade from FC5 to FC6 using the method described here http://fedoraproject.org/wiki/YumUpgradeFaq with terrific results. Haven't used the FC5 system for 7 months. Upgraded to latest versions of everything, 374 packages, took a few hours. Then cleaned up the rpmnew and rpmsave as described in the link above. Switched repositories also using the commands from the wiki for Fedora and from here http://www.mjmwired.net/resources/mjm-fedora-fc6.html#yum (Thanks Mauriat). I had to use the version for Fedora C(omprehensive) 7 for the livna gpg key as it did not work with the FC 6 version. http://www.mjmwired.net/resources/mjm-fedora-f7.html#yum Then just run yum upgrade. With 2141 packages it took approximately 1 hour to download headers. There were only 5 dependency failures. This is phenomenal! Error: Missing Dependency: libgcj.so.7 is needed by package eclipse-pydev Error: Missing Dependency: libgnutls.so.12 is needed by package samba-swat Error: Missing Dependency: libgnomecanvaspixbuf.so.1 is needed by package gtkhtml Error: Missing Dependency: libgnutls.so.12 is needed by package samba Error: Missing Dependency: mono-core = 1.1.13.7-3.fc5.1 is needed by package mono-basic Unfortunately it took me 4 total tries to correct them. The solution was to delete the individual package and dependencies. There were only three dependencies. On the last try I discovered the gpg problem with livna. yum doesn't keep any state until you get through the dependency stage, so it was a very long test cycle, 1 hour each trial as the headers were downloaded. >From here on there were no issues, just a long wait. It took approximately 10 hours to download all the packages, and approximately 3 hours to install them. The downloads automatically rotated among 4 mirrors. If I was going to do it this way again, I would use the baseurl method described below to select 4 mirrors that were close and fairly lightly loaded and reasonably fast. Probably could run overnight once dependency issues were resolved. The system boots cleanly. However, the wallpaper is missing in the gui, and the format is still the fc5 format instead of the fc6 format. In a month or so when the load on the fc7 mirrors is lower I will upgrade this system to fc7 the same way. However, instead of using yum to get the packages I will use wget -c to download all packages in a repository to the hard drive. I'm not sure how to use that as the repository for yum; it looks like it can be done with a baseurl directive in the /etc/yum.conf.d/"main".repo file. This should cut the header iteration time to about 15 minutes though it won't help with install time. It will double hard disk requirements. All in all a very positive experience. Thanks to everyone who made this possible, the documenters, the dependency maintainers, and the good samaritans. I still can't believe that with 2100+ packages and all their interwoven dependencies there were only 5 dependency issues. Amazing.
