Preamble: Few years back I dropped my laptop, it subsequently failed to mount the sda1 disk. I recovered it mounting it with a live usb ubuntu distro. Ever since, my laptop has never been as smooth anymore.
Q: I am getting this warning message during update:
cryptsetup: WARNING: failed to detect canonical device of /dev/sda1
a view at /etc/fstab and /etc/crypttab shows:
$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 /dev/sda1 / ext4 errors=remount-ro,user_xattr 0 1 /dev/sda5 none swap sw 0 0
$ cat /etc/crypttab # <target name> <source device> <key file> <options>
I am on ubuntu 14.04 LTS, uname -a shows
$ uname -a Linux alessio-laptop 3.13.0-77-generic #121-Ubuntu SMP Wed Jan 20 10:50:59 UTC 2016 i686 i686 i686 GNU/Linux
I have been looking at other posts, but I am concerned with the errors=remount-ro and none tags in the fstab file. I am also pretty sure my disks are not encrypted.
Is this affecting the performance of my system, or even causing bigger errors? How could I fix it?
