Thread: Offline Install Problems (NOTE: I did do my research)

i running ubuntu 11.10 , trying install several applications on offline pc. have heard of "keryx", not work well. "aptoncd" next on list. works when creating dvd contains needed deb files, unfortunately application needed on offline pc. after research have found need copy deb files dvd created "aptoncd" "/var/cache/apt/archive" directory, after need run "sudo apt-get install vlc" command (where vlc represents other application need install).
first problem encountered when trying copy deb files required directory. system generated error stating "permission denied". found solution have run "gksu nautilus" command, after can copy deb files need them. ran "sudo apt-get install vlc" command , worked fine.

kicker.

formatted pc, did clean install , tried above process. time "gksu nautilus" command generates error stating need create ".config" file in root directory (although exists). ran "mkdir /root/.config/nautilus" command. command works once have attempted run "gksu nautilus" command. if run "mkdir /root/.config/nautilus" before running "gksu nautilus" command error message generated stating directory cannot found.

run "gksu nautilus" command, receive error message, run "mkdir /root/.config/nautilus" command , run "gksu nautilus" command. allows me copy deb files "/var/cache/apt/archive" directory.

when try run "sudo apt-get install vlc" command system generates error stating package cannot found.

why happening? exact same process generating different results.

did find command installs deb packages copied directory, there applications not want install on pc. also, command install random packages might have been copied on dvd created "aptoncd" , don't having random packages on pc.
advice?

after copying deb files /var/cache/apt/archive have done...

code:

sudo apt-get update

then try...
sudo apt-get install <whatever package name>
