I read the guide u just send me and I read it before you send
it to me, and as I said I didnt had access to do any of these, now with the sudo nothing happen just a bunch of errors wich ask me to apt-get update. Ok its realy confusing, if each time I open my laptop wich is protable and its portable to take it to any place with me I have to conect to internet download updates and run a bunch of commands in order to make my os work corectly than.... its kinda weird. However if it doesnt require any network downloading I dont mind just typing a bunch of commands but what gets me nevrous is that it needs to download some files.
