Choose to update Minion and restart. (It won't restart)
Before you start minion we need to apply the patch manually. Navigate to the folder you are running minion from and you should see a new folder named "null" grab the Minion-jfx.jar from there and copy over the old Minion-jfx.jar in the parent directory.
now start minion again java -jar Minion-jfx.jar and it should work like mine...
Finally, a usable set of instructions that work! You are a saint.
I am using these instructions with the Steam version of ESO on Linux Mint, and it is working perfectly.
For those that are doing the same, and have no idea where to find the AddOns folder, it is buried in a somewhat weird place. Try turning on "Show hidden files" and look for someplace like this:
~/.steam/steam/steamapps/compatdata/306130/pfx/drive_c/users/steamuser/My Documents/Elder Scrolls Online/live/AddOns
