Linux Mint fails to install in my new LINUX MINT 18.2 upgrade. Help?
Determine, which Ubuntu version your Linux is based and make sure, that you install GO for that Ubuntu version.
Else: You can grab the GO source package for that Ubuntu version (3 files) and compile it yourself:
I had trouble installing Grand Orgue on Linux Mint today - the key seems to have expired. Here's what worked:
sudo apt -o Acquire::AllowInsecureRepositories=true -o Acquire::AllowDowngradeToInsecureRepositories=true update
sudo apt-get -o APT::Get::AllowUnauthenticated=true install grandorgue
Installing the deb package manually didn't work as it came up with an unsatisfiable dependency (grandorgue-resources if I remember correctly)
Hope that helps
The repository signing key is automatically manged by the open build service - as each key has an expiration date, it changes from time to time.
You can always lookup the current key:
I don't keep track of these processes - there must have been a key change before October 2017.
