Description of problem: The installer stops during an upgrade because it says it can't find /. But it's already found the relevant partition as the root of a FC6 installation. The fstab entry is LABEL=f7-slash / ext3 defaults 1 1 just like in the release notes. blkid reports /dev/hda2: LABEL="f7-slash" UUID="0ab4911b-1c77-4af2-a586-8cc1d0934d1e" SEC_TYPE="ext2" TYPE="ext3" and the grub.conf entry is kernel /vmlinuz-2.6.20-1.2952_1.fc6 ro root=LABEL=f7-slash ... The installation boots OK. Version-Release number of selected component (if applicable): How reproducible: repeated several times Steps to Reproduce: 1. run installer 2. select upgrade (the only) existing installation 3. Actual results: error message, suggesting fstab error Expected results: installation to start Additional info: Your Release Notes are terrible here. You should suggest e2label for doing partition labelling. You should explain what the constraints on partition labels are: is / allowed or not? Is the grub.conf entry root=LABEL=... or just root=... as your example has it? (The latter wouldn't work for me.)
I changed the label on the / partition to "/fedora" and lo and behold the installer accepted it. So this is either a workaround for a bug in your installer, or your Release Notes do not make it evident what the constraints are on the root-partition label; in particular, the example given there doesn't seem to work. I won't change the status pending your verdict.
What is the exact error message you are seeing here?
I didn't write it down. The closest I can come is "Can't find entry for /. Probably something wrong with /etc/fstab." I believe I was offered an OK button as the only option; it re-booted the system.
I believe this is fixed in F8 test 1. I tested with LABEL=/ and LABEL=fc6-slash, and it is upgrading just fine. Feel free to reopen this bug if you continue to experience problems.
