Fix Arch release

The Arch User Repository (AUR) can from time to time become outdated, containing a version of Bisq that will not be able to trade on the p2p network.

At the time of writing, AUR contains 1.8.0, but current version is 1.8.2; the following instructions should get you a working setup.

Method 1: edit the cloned repository

This method has been user-tested and reported for migration from 1.8.0 to 1.8.2.

Clone the AUR package for bisq curent version 1.8.0 and change to download directory
git clone https://aur.archlinux.org/bisq.git
cd bisq

Edit the PKGBUILD file changing the version, and updating the sha256 checksum for the bisq-1.8.2.tar.gz file

nano PKGBUILD
or
vi PKGBUILD

and then change
pkgver=1.8.0
to
pkgver=1.8.2

and

sha256sums=('ca636152863a9cc587d8d2b00476abd6fab854ae0b3513950d001f23cb0a1a53'
to
sha256sums=('d69bab29875eed312811cb34a84ac7920acac74f9a86eb637e56e92e5fcbcbbb'

then build and install bisq:
makepkg -si

Method 2: run the binaries downloaded from the official website

The following method will work with any future version of Bisq.

Download the deb package from https://bisq.network/downloads/, open it using archive manager, and extract to disk the file data.tar.xz inside of it, then run opt/bisq/bin/Bisq under the directory you extracted it to.
