I encountered the same problem as Riobard. I booted from a USB drive and tried to install, but /cdrom was mounted (same error message as above). I am trying to install to /dev/sdb (which is a new hard disk) but Ubuntu mounts it to /cdrom. I tried but was unable to sudo umount /cdrom before installing (I tried using lsof and fuser to see if there were open files). I ran ubiquity -d but the install did not succeed.
The result is that I am unable to install ubuntu on this machine. I have attached /var/log/syslog and will send the other requested log files. ** Attachment added: "syslog" http://launchpadlibrarian.net/20931595/syslog -- usb startup disk failed to unmount /cdrom when change partition tables https://bugs.launchpad.net/bugs/292493 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
