Linux wallet where? I think I have some issues due to the fork but no way to update.
I tried deleting and redownloading the blockchain but it still hangs.
Your best best is compiling it yourself on whatever system it's pretty easy.
Skip this step if you already have the dependencies:
sudo apt-get install build-essential libboost-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev qtcreator
And make sure you have git:
sudo apt-get install git
Then git 'er:
cd ~
git clone git://github.com/usecredits/Credits.git
Open the credit-qt.pro file in the "Credits" folder that was just downloaded to that directory..
Build and run.
That's about it! Ill make an executable if it will be easier.
