I've been advised to check some log files in the flaky 14.04 pre-installed by Dell on my Inspiron 15-3552 laptop. I've booted from a 14.04 live-USB but I reckon the folders shown under Files/Computer are the ones in the temporary Ram-held OS as the edit to /etc/rc.local to disable Bluetooth on startup, which I made before the OS went flaky, is absent. I guess it's necessary to use Terminal, but how do I get to the correct /var/log/apt folder which holds the log files relating to the OS on the HDD?
Mount the root partition of the internal drive at /mnt,
sudo mount /dev/sdxn /mnt
where x is the drive letter (x = a for the first drive), and n is the partition number (often n = 1 or n = 5), so for example
sudo mount /dev/sda1 /mnt
The following command line
sudo ls -l /mnt/var/log/apt
will list the files in the folder you want to examine.
If you want a command-line solution, try this -
You must first identify the partition you need to mount. You can do that using the program
gparted or the command
lsblk. It will be of the format sdXY where X is a letter and Y is a number.
Once you have identified the partition, you can mount it as follows.
Create a mount point
sudo mkdir /media/mount
Mount the partition
sudo mount /dev/sdXY /media/mount
Now you can use
nano to look at the logfiles
nano /media/mount/var/log/[directory of interest]/[logfile of interest]
