Could not open lock file /var/lib/dpkg/lock
While using apt-get install or apt-get upgrade and also trying to install any software through apt command getting an error like.
[email protected]:~$ apt-get install yum 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?
Now, what you have to do is simply type sudo su Now you have super user privileges.
[email protected]:~$ sudo su [email protected]:/home/ubuntu#
Now, just type apt-get update this is for updating your source list.
[email protected]:/home/ubuntu# apt-get update Ign cdrom://Lubuntu 15.10 _Wily Werewolf_ - Release i386 (20151021) wily InRelease Ign cdrom://Lubuntu 15.10 _Wily Werewolf_ - Release i386 (20151021) wily/main Translation-en_US Ign cdrom://Lubuntu 15.10 _Wily Werewolf_ - Release i386 (20151021) wily/main Translation-en Ign cdrom://Lubuntu 15.10 _Wily Werewolf_ - Release i386 (20151021) wily/multiverse Translation-en_US Ign cdrom://Lubuntu 15.10 _Wily Werewolf_ - Release i386 (20151021) wily/multiverse Translation-en
After finishing this now you can get any software by.
apt-get install *******
