After executing
wget http://all.repository.backtrack-linux.org/backtrack.gpg -O – | sudo apt-key add -
I'm getting an error like gpg: no valid OpenPGP data found.
How can I complete this task successfully?
go to http://all.repository.backtrack-linux.org/backtrack.gpg ctrl-a to select all mouse to copy (ctrl-c sometimes doesn't work...)
back on your system in shell go into etc/apt dir sudo gedit backtrack.gpg paste the contents save
then in same dir issue command sudo apt-key add backtrack.gpg then do
sudo apt-get update sudo apt-get upgrade
(assuming you have added the three lines to the sources.list for backtrack)
-O
switch. There should be short-dash, or minus. Do you use automatic patterning?
