Back in 2016 - 2018... I was a Linux Mint fan. I use the word "fan" loosely. Because when it comes to OSes, I believe in the "whatever works for you" philosophy. But lately I've been feeling sour towards several distros.
This past summer I ran into some trouble with Linux Mint 20, MX Linux 19.2, and Xubuntu 20.04. It was the same basic problem with all of them. I really scratch my head about it because I'm using them the same way I used past versions without a problem. I guess all of a sudden something has gotten either heavy or incompatible or whatever, with one of my old computers. I guess that is ok because the machine is old and I haven't tried hard enough to replace it.
The other day I ran into a big problem. I was on my fastest newest machine running Linux Mint 18.3. All of a sudden about 5 PPAs stopped responding. At first I thought it was the PPAs. Figuring that Linux Mint 18.3 is almost at the end of it's life cycle, I decided to replace it with Linux Mint 20. To my surprise no PPA would work on it either. The system seemed to update just fine, so what was up with the PPAs? I grabbed my old Xubuntu 18.04 install and put it in the computer. When I tried to update it I noticed that the PPAs weren't working there either. It was this point, I decided to reboot my Modem and Router. After that then the PPAs started working again.
Yesterday I was doing stuff on my Linux Mint 20 XFCE install and found out that I couldn't get into my firewall settings from the gui. After discussing it on the Linux Mint forums we discovered I had a bigger issue with it then I knew. I did a lot of searching around. I found some bug reports but no solutions. I decided to reinstall the entire system. After spending about 5 hours putting software on it I decided to take a look at gparted. I noticed that I had two efi partitions on it. Now I'm thinking about scrapping this install and starting all over again. After discussing this in the forums, it appears that there is some kind of install bug in the Linux Mint installer. It seems it gets messed up when you install on an efi computer in Legacy mode. The only way around it is to manually partition before installing.
Since my computer can do efi or legacy it's hard to decide which way I want to go with this. Or do I want to change to a different distro.
