Hi Wilson,
I'm CC'ing this to the mailing list for reference purposes.
This problem usually arises when:
1. Running 2 apt-get install commands at the same time
For apt-get to work, only 1 process should be running. In case you want
to install multiple software at the same time, just append it in the
command:
$ sudo apt-get install firefox chromium gnome-do
2. When apt-get update process is terminated before it was able to
complete update progress
When an update is in progress, apt-get will download files from the
source and checks with current configuration. When this process is
terminated, it was not completed cleanly and residues are left which
causes the error
Resolving the issue:
Since we know that there are residues left, the only logical way is to
delete the contents at the stored location. In this
case, /var/lib/dpkg/lock
This location is protected by root user. So in order to remove the file
'lock' you need to use sudo to remove it.
$ sudo rm /var/lib/dpkg/lock
sudo = run the command as root/superuser
rm = the command to remove the file/directory
/var/lib/dpkg/lock = the directory and the file to delete, directory
= /var/lob/dpkg, file = lock
$ sudo rm /var/cache/apt/archives/lock
similar to the latter command, in this case directory
= /var/cache/apt/archives, file = lock
The first deletion will remove files that was being used when
performing update
The second deletion remove files to install which was not completely
downloaded
I would suggest you learn a bit of Linux bash/command line syntax so
that you are able to grasp and understand a bit to work your way around
Linux environment.
Linux Command Syntax:
$ = user shell
# = root shell (administrative power that is dangerous if not used
correctly
$ command [OPTION] [FILE]
This refers to simple commands such as rm (remove/delete), cp (copy),
mv(move/rename)
You can access the manual to learn how to use the commands in Terminal,
just type:
$ man rm
man = manual
rm = the command you want to learn more about
Hope these help!
