I can't install Tor Web Browser

[firenice03]

it worked thank you but do i have to do the same method everytime i install something

You shouldn't have to. You can rerun updates when ever you like..

can you please explain to me these commands do

Sure... I'll do my best  ;D

Code:

sudo apt-get update

This is the command line way you run updates in LL, if you use Run Updates from any of the gui based apps (Lite Updates/Updates from Welcome) this command runs in the background...

Code:

sudo apt-get update && sudo apt-get install APP_NAME_HERE

This is the combination of 2 commands... The 1st command (update) runs updates and upon success(the &&) install the app listed.
apt-get install is the install command of apt-get essentially what Synaptic does in the background. There are other variables remove purge, update and others.

Code:

sudo dpkg --configure -a

This was actually being told to you within the error messages when updating. At some point there was an interruption this command corrected it. dpkg relates to the base package system.
