PZ HELP

I'm running 11.04 (assume you missed the 0 in your post), and have no issues.

I just installed the game
and do not get whats wrong with game just wont update.
Or should i do a manual update?

Could it be that you don't have enough disk space for the update to be downloaded?

/home partition has 22.8 Gib available i think its enough for the game.
Still same problem

Make sure that ~/.vendetta and everything within is readable and writable by your user account.

Otherwise, there is a support link to the left of the site that you can use to get the devs attention faster than this thread will.

Or you could just uninstall it via Synaptic Package manager, (purge) and then just download and install it from here: http://www.vendetta-online.com/x/download?platform=linux&accept=y

Just follow the instructions on the above page and you should be all set. Make sure you don't sudo, just install it normally.

did chown myusername .vendetta
and now it works thank you GOD,
and u helping ppl. see you soon

Good to hear!

Might as well check your permissions on your /home/username/bin/vendetta while your at it.

You might want to chown -R yourusername /your/home/.vendetta just to be sure you can update later. Anything still owned by root won't be able to be written to.
