Install bitcoin client debian
Bitcoin Classic ships both a background application called daemon in Linux bitcoind and a graphical application bitcoin-qt , you will have to choose one to run. The daemon version of Bitcoin Classic can run without graphics systems installed on the system and the only way to interact with it is to use the command line. Bitcoin Classic packages are created such that the bitcoin-qt application has to be run in a desktop session by the local user and it will download the blockchain into that user's homedir.
Pick an install method To integrate best with Linux, the Bitcoin Classic team has prepared several options based on which distribution of Linux you are running. The Ubuntu family of distros are supported using ubuntu's launchpad. Debian all-in-one download build, which you can find in downloads. Bitcoin reads a config file called bitcoin. It is worth noting that editing your config file requires a restart of the software to activate your changes. Unlike other versions of Bitcoin, typos will cause an error and the node will request you fix it before it starts.
Installing the package will auto create a 'bitcoin' user and group. Please make sure you don't already have those before installing, or your install will fail. Running the daemon with systemd will disable the wallet functionality, run it manually, as your own user, if you need a wallet.
For those multi-user machines we recommend removing the word-readable bit and putting selected users in the bitcoin group. Compiling from source offers one option, but involves many steps. A more direct route is to install a precompiled binary from the command line.
The method described here uses Terminal, an application into which text-based commands can be issued. Take a moment to become familiar with how Ubuntu mitigates the risks. This last command may take some time, during which both Bitcoin Core and all of its dependencies will be installed. Prerequisites Ubuntu does not yet come pre-packaged with Bitcoin Core.
