Inspired by this question.... I am the sole person using my system with 12.04. Every time I issue a sudo command; the system asks for the user password (which is good in its own way). However I was thinking; without activating the root account; how can I execute the sudo commands which will not ask for user password to authenticate. NOTE: I want to execute sudo command without authenticating via p
I added some extra repositories with the Software Sources program. But when I reload the package database, I get an error like the following: W: GPG error: http://ppa.launchpad.net trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8BAF9A6F I know I can fix it using apt-key in a terminal, according to the official Ubuntu documentation

I'm up to setting up some mining rigs running Ubuntu. I use Nvidia GTX 970 and GTX 780 GPUs. I installed the 16.04 LTS server distro and it's working fine. I can tweak some GPU params using nvidia-smi. However, over- and underclocking can only be done with nvidia-settings utility which I have trouble running. The error msg is this: Failed to connect to Mir: Failed to connect to server socket: No s
I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - Ctrl+c, Ctrl+z and Ctrl+d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. whe
I've become addicted to Byobu and I've recently shifted from bash to zsh; Now I want to combine the two, however I have a one initial pre-requisite: I cannot make zsh the default shell for my user as it's a shared account and the rest of the team aren't as zsh happy as I am - That rules out the 'chsh -s /bin/zsh' option.

I just wanted to be able to add inside some fish configuration file (don't know which/where) the same function as this: export PERL5LIB=/home/iaco/workspace/perl:/home/iaco/devtools This line was added inside the .bashrc file and it was able to export the variable each time I opened a terminal. Is there something like that for fish? I know that I can export variables in fish using the "set" comman
