I think i am running in to the same thing as the topicstarter, (newby i am) its in the start of the dli coarse, were the advise u to enlarge the swap memory to 4gb,
when i try to walk the path they instruct to do i also get an : permission denied.
sudo echo "/mnt/4GB.swap swap swap defaults 0 0" >> /etc/fstab
this then returns in :
bash: /etc/fstab: permission denied
I am not sure what could be wrong. (other than not having the permision :-))
(Found the missing information for completing this step in the training, not shure if it’s part of the course or not? It is presented in the videoclip)
