GitKraken on Linux Mint Cinnamon Edition
Scenario
You install GitKraken using the basic instructions on the website:
wget https://release.gitkraken.com/linux/gitkraken-amd64.deb
dpkg -i gitkraken-amd64.deb
It installs successfully. You start it and... nothing.
Solution
I learned that you can fix this behavior by installing: libcurl3.
sudo apt install libcurl3
