Problem found and solved. The internal SSD on my netbook has died, so I boot from a tiny USB flash drive. In order to install, I booted off the netbook live USB image on one USB flash drive and installed onto the tiny USB flash drive.
During installation, the destination USB flash drive was given /dev/sdc. I told the partitioner to partition /dev/sdc, and to mount /dev/sdc1 as /, and there is an appropriate entry in /etc/fstab. The system boots up correctly. The boot drive is automatically given /dev/sda and seems to be mounted automatically. The USB SD card reader is given /dev/sdb. When plugging in another USB flash drive, it is given /dev/sdc. However, it cannot be mounted because of the entry in /etc/fstab trying to make it mount as /. When I removed the entry for /dev/sdc1 in /etc/fstab, the system works as expected. How do I mark a bug as 'No error'? ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- USB flash drive and hard drive are not mounted https://bugs.launchpad.net/bugs/574198 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
