I think Mint is better out of the box than it used to be. I was on it maybe 5 or 6 years ago and had to troubleshoot a few issues, but I just came back to it a few months ago and everything worked flawlessly out of the box.
I’m relatively new to Mint, but I thought that sudo apt update just checked for updates and sudo apt upgrade -y was for actually installing the updates. I don’t see why that would break it though.
You mean 1%?
