At the moment it does not look easily possible to install Armory Wallet on Fedora. Here are some notes about trying to get it to work.

The following person on Reddit was able to get it working on an older version of Fedora.

The issue is that pyqt4 and pyqt4-devel are not available on the latest versions of Fedora.

The following prerequisites need to be installed

sudo dnf install git nano qt qt-devel python-devel libtool lmdb swig python-psutil

Other notes.

Armory relies on Bitcoin Core. You can install BitCoin core from https://bitcoincore.org. It will need to be fully synced which can take a long time “as in days/weeks”. Note that Armory will not work if you have the blockchain pruned. Which means you’ll need about 500GB of space for the BitCoin blockchain.

I am planning on attaching the vbios for MSI MECH RX 5700 that “makes” it a 5700 XT and increases the hashrate to 53.

Nanominer – Lower intensity for GPU

By default Nanominer sets the memTweak option to 1. This slightly improves memory timings. However it introduces a little bit of UI lag. This can be a problem if you are trying to use your computer for other tasks. The simple resolution is to change/add the memTweak setting to 0.

memTweak=0

Example config

wallet = WALLET_ADDRESS
; Coin to mine.
coin = ETH
; (Optional) Rig (worker) name.
rigName = EthMiner
memTweak=0

These instructions are for installing the Ravencoin wallet on Fedeora, but the instructions should work for CentOS, and be similar for Debian/Ubuntu Distros.

Note if you don’t have wget installed, you can install it by running

sudo dnf install -y wget

Unzip the downloaded files

tar zxvf fedora27-x86_64.tar.gz

Change to the new directory

cd fedora
