Description of problem: Installation can not be completed due to an error with message "An error occured unmounting the CD...." Version-Release number of selected component (if applicable): Fedora core 6 How reproducible: Guranteedly reproducible Steps to Reproduce: 1. Download Fedora core 6, burn DVD 2. Start installing Fedora core 6 on a PC 3. After selecting language etc options (select all default options), the point where it should start installing components, it stucks with following error message -- An error occured unmounting the CD. Please make sure you're not accessing /mnt/source from shell on tty2 and then click OK to retry. Actual results: Installation stucks with following error message -- An error occured unmounting the CD. Please make sure you're not accessing /mnt/source from shell on tty2 and then click OK to retry. Expected results: Continued installation Additional info:
Can you switch to tty2 and grab /tmp/syslog and /tmp/anaconda.log? Did you verify your media with mediacheck?
I got this error as well on a tested and verified FC6 install CD#1. Moreover: I got it after doing a "workaround" to stop the installer from crashing on selecting additional repositories after specifying a static IP address. I left DHCP enabled, enabled Fedora Extras, chose Customize now, and clicked Next. Errors in other terminals: WARNING: Failed to get http://download.fedora.redhat.com/pub/fedora/linux/extras/6/i386/repodata/repomd.xml from mirror. ERROR: exception in unmountCD: (16, 'Device or resource busy') When I tried to umnount manually in sh-3.1: #umount /mnt/source/ umount: Couldn't umount /mnt/source: Function not implemented
I can confirm this also. Burned FC6 DVD two times on two different drives, mediacheck ok, selected components for install (default + KDE option) and at the point where it is checking dependencies for selected packages it fails fith "An error occured unmounting the CD" with the all symptoms described above. (I found that if i try to install default set of packages installation can be completed successfully).
> ERROR: exception in unmountCD: (16, 'Device or resource busy') This usually (but not always) indicates a hardware failure. Without the /tmp/syslog and /tmp/anaconda.log from your system, we can't diagnose the problem completely. Please attach those log files.
> This usually (but not always) indicates a hardware failure. I can confirm that this was not a hardware failure: I was able to complete the installation successfully, on the same hardware and same installation media, by leaving the default networking (specifically, enabling DHCP) and "Extra Repositories" (specifically, not choosing to install extras during install) selections intact.
