I have downloaded the bitcoin.tar.gz file, extracted it on the Desktop and executed the following commands in Desktop/bin/32:
chmod u+x bitcoin-qt
./bitcoin-qt
The result is: "No such file or directory" (but it's there!)
If I type ./ bitcoin-qt the result is: "Is a directory"
So I tried with:
$ sudo apt-add-repository ppa:bitcoin/bitcoin
$ sudo apt-get update
$ sudo apt-get install bitcoin-qt
...but the result is: "Some packages could not be installed. The following packages have unmet dependencies:
bitcoin-qt: Depends : libqrencode3 (>= 3.2.0) but it is not isntallable
wtf?
EDIT: it's from a live cd
