I'm not sure if this will work or not but it's worth the try right?
sudo chown [groupaname]:[username] [filename]
sudo chmod 777 [filename]
u can use -R in both commands for recursive if you are using a directory
instead of file name
// just a tip, if u can't open rar files you can install the package 'rar'
or 'unrar' , never tried the first one, i always install unrar i dunno if it
installs the other one with it or what, i just read about it.
