I use Chrubuntu and I have a extremely small amount off space on my computer I want to download steam but dont have enough space for my games. I heard you could download games onto a External Drive so i tried to but it wont allow me to change the file permissions. Does anyone know why and how to fix it. Please help Im pretty desperate
Probably your external drive is formatted as FAT32. That doesn't have the permissions.
If you don't care much about the interoperability with other OSes, reformat the external drive to ext4.
