I've grown tired of always invoking apt-get update and apt-get upgrade under sudo and typing my password, so I have added the following line to my /etc/sudoers file using visudo:
<myusername> ALL=NOPASSWD: /usr/bin/apt-get
Unfortunately when I invoke apt-get I am met with the following error:
<myusername>@sputnik:~$ apt-get update E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied) E: Unable to lock directory /var/lib/apt/lists/ E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
I have tried to add the following (fairly obvious) line to /etc/sudoers too but to no effect
<myusername> ALL=NOPASSWD: /usr/bin/dpkg
What must I do?
