After trying to install Limewire, (first Frostwire, but it ignored me) Synaptitude have been flipping out. I get an updates icon on the taskmenu saying:
I tried downloading the Limewire deb from the limewire homepage, but it doesn't install with this message:

Point-And-Click installation with the .deb;

Could not open LimeWireLinux.deb
The package might be corrupted or you are not allowed to open the file.
Check the permissions of the file.



I did check, and granted both my group and user read+write permission, and checked the Execute box. Same error message.


Terminal installation with ./LimeWireLinux.deb is not possible. Nothing happens. Output:

$ ./LimeWireLinux.deb
./LimeWireLinux.deb: line 1: syntax error near unexpected token `newline'
./LimeWireLinux.deb: line 1: `!<arch>'


Updates is possible, but when i open Synaptic i get:
E: The package limewire-basic needs to be reinstalled, but I can't find an archive for it.
E: Internal error opening cache (1). Please report.

Testing installation gives:
~$ sudo apt-get install frostwire
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: The package limewire-basic needs to be reinstalled, but I can't find an archive for it.

should be PS: also, run "sudo apt-get update" and "sudo apt-get -f install" to fix your dependencies.

I always run sudo apt-get update. I said updating worked, didn't i?

Anyways, tried sudo dpkg -i LimeWireLinux.deb.
And that worked, fixed it right up.
That's Comradé, fast and useful reply.
