I cannot access my Ubuntu-system anymore (see this question). Now I'm booting my computer with a bootable-Ubuntu-usb-stick, this works and I try to access my files to keep my files on the hard drive safe. But when I try to copy the files to an external drive I get the error message
The folder xxx cannot be handled because you do not have permissions the read it
So I tried it command line by first trying switching user (the owner of the files), but this gives:
No passwd entry for user 'waanders'
I cannot access my own files, please help.
sudo -i
did the trick. Thanks a lot! – waanders Feb 14 '15 at 13:45
