Can't copy or past files in other locations in Ubuntu

Question

I have installed Ubuntu in my laptop by partitioning HDD, but now I couldn't copy or past files in other locations of my lap it's showing

"Error while copying, the destination is read-only".

Why is that????

Answer 1

This might be a couple issues: the UUID of the filesystem might be the same or it could be that the filesystem is read only because it's not mounted with the correct command. I checked the tags and saw dual boot so that's a possibility.

To check the UUID use (If the external UUID is the same as the internal continue, if not go to solution 2)`

sudo blkid

Now use a file system check on the respective external filesystem as super user.

e2fsck -f -p -C 0 /dev/sda5

Show me the results.

Now here is the second solution if the UUID is different.

First Type in

id

to get the uid and gid of the following command.

sudo mount -o remount,uid=1000,gid=1000,rw /dev/sdc1

CHECK GPARTED FOR THE FILESYSTEM IN QUESTION
