Everyone who uses Linux for crypto currency should use Arch Linux.
I was an Ubuntu and Debian linux user, due to the privacy issues of Ubuntu. I have converted to becoming an Arch Linux user. After being an Ubuntu and Debian user for over 20 years. I discovered that the compiling of new altcoin and other crypto currency wallet a pain in the butt.
I have only being a Arch Linux user for 2 days, and I can stay this wallet installing is a breeze. The AUR has all the wallets no matter how exotic, they have it. And just downloading from AUR and build the wallet. All is done without any problem.
Everyone who uses Linux should consider using Arch Linux as their main choice when use for crypto currency. Also Arch is total open source, unlike Ubuntu, which is sponser by a South African company which have closed sourcecode. Also Ubuntu have privacy problem, as it send information back to their company without your consent.
That is my 2 cents.
What the hell is easier than:
sudo apt-get install bitcoin-qt
Also, Ubuntu is completely open source and I have no idea why you would think otherwise. The word "ubuntu" is an African word and was the inspiration for which the software Ubuntu is developed after. Canonical is the main developer behind Ubuntu and is primarily UK-based. The man who started Canonical, Mark Shuttleworth, is a south-African entrepreneur, however him and the fact that Ubuntu is an African word are really the only two ties to Ubuntu and South Africa. The Canonical headquarters in located in London.
It should also be noted, for those considering a switch, that although Arch Linux is good, for some novice users it can be a more complicated install. It is also not Debian-based, which Ubuntu is. Arch is based on Gentoo and used Pacman instead of the more common Aptitude (i.e., apt-get commands). So performing terminal commands will be different and certain things will need to be re-learned.
As for the Ubuntu privacy concerns, what the OP is referring to is usage statistics and error reporting, which literally EVERY operating system from Windows to Mac has. The usage statistics that Canonical monitors have nothing to do with your privacy, it's not like they're logging everything you type. Error reporting is very common as well. Both of these are able to be disabled on Ubuntu.
