My problem is that sometimes the whole system is read-only, especially when I use root operations (apt-get, ssh and even when the qBitorrent is checking the downloaded files), when I try to trace the unit I get this:
user @ group: ~ $ sudo mount -o remount, rw / [sudo] password for user:
sudo: it is not possible to open / var / lib / sudo / user / 1: The file does not exist or
the mount directory: can not remount block device
/ dev / sda1 as read-only, is write-protected
After this, any operation I do, whether in xfce or nautilus, does not allow it because all icons appear with a padlock, and in the permission section in the file information it appears that the owner is root .
I'm listing my system information:
S.O = Xubuntu (Ubuntu 14.04.4 LTS)
CPU = Intel Core i5 M460
SSD = KINGSTON SV300S37A120G (120GB)
GPU = nVidia GeForce m310
