sudo gedit /etc/hosts
在末尾添加127.0.0.1 release.gitkraken.com

sudo apt install curl
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt install yarn

curl -fsSL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt install -y nodejs

如卸载nodejs后，后面update会出现命中:5 https://deb.nodesource.com/node_12.x focal InRelease
需要在/etc/apt/sources.list.d/目录下的nodesource.list和nodesource.list.save文件中删除

略

rm yarn.lock
yarn install
yarn build
sudo node dist/bin/gitcracken.js patcher

如果是root用户会发现GitKraken无法启动，需要修改快捷方式
有三个快捷方式，分别加上--no-sandbox

Exec=/usr/bin/gitkraken --no-sandbox --uri=%U
Exec=/usr/share/gitkraken/gitkraken --no-sandbox %U
Exec=/usr/bin/gitkraken --no-sandbox --uri=%U

/usr/share/gitkraken/resources/app.asar.unpacked/src
