I am running 13.04 and in terminal I am trying to install guitar pro 6 for linux as it will not install with Ubuntu software center. I am in the correct directory and if I ls the directory, I get GP6.deb which is the folder I downloaded guitarpro6 to, but when I use apt-get install GP6.deb Terminal accepts the command but says it cannot locate the file.

Am I using the correct command or must I do something else first?

.deb files are installed using the dpkg command. So use the following command:

sudo dpkg -i GP6.deb
  • -i tells dpkg to install

If it gives you errors about other packages/dependencies, run the following to fix it:

sudo apt-get install -f
  • -f tells apt-get to fix missing dependencies
  • Hi I have done this and it now shows this: deprima@deprima-K53U:~/Downloads$ sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. deprima@deprima-K53U:~/Downloads$ apt-get install GP6.deb 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? so Im unsure what to do now?

  • @user172503 No, you didn't do as in the answer. Read carefully. You made several mistakes: mixed up dpkg and apt-get, you omitted sudo and the order is wrong.

  • @user172503, forget about apt-get install GP6.deb, that is not the correct command. Just enter in both the commands in my answer (exactly as they are) in the order shown, and you should be on your way.
