I wouldn't normally have a system with systemd on my hrdware, but this is a bit unusual, and Linux Mint is only istalled to run one application/program.
A back story.
Quite a few years ago I bought the Logos Bible Software to help with my studying of the bible and Christianity. They made only versions for Windows and Mac. Not for Linux, although many had requested in the forums, they refused. The Logos software was/is developed around the .NET framework. To put it on the Mac they used mono - the opensource version. So I bought a Mac (better than Windows) and dual booted with Linux.
I had tried to install it on Linux with Wine, but that didn't work.
Rcently though, some resourceful fellows (to whom I'm very grateful) have managed to install and to run well on Linux using a modified version of wine. This wine was developed on/for Ubuntu.
It will also work on Linux Mint, and although some have had success running it on Debian and Arch, I have not tried to hard to do the same as they all have systemd, I went for the easy option.
Why not Ubuntu? I snaped over snap. And that is for another time, just to say I'm grateful Mint has stopped snaps altogether. A wise move in my opinion.
So here we are with Linux Mint.
I have just upgraded Linux mint from 19.3 to 20 without any problems. Here's what I did:
Your mileage my vary and it is your choice. This worked for me, it may not work for you. I have a fairly stock install.
- Downloaded Xfce 20 and made bootable USB.
- Booted from usb, checked everything worked as it should. Copied /etc/apt folder to hardrive.
- Booted into local Linux Mint 19.3.
- Terminal "sudo thunar" to give elivated permissions, navigated to /etc/apt/ and replaced most of the files from version 20.
- Closed Thunar & terminal.
- Opened update manager.
- Reloaded package info from new repos.
- Updated update manager.
- Checked for strange behaviour/upadtes and what's being deleted <= really important!
- Hit update and waited (900+ packaged download & install).
- Opened Teminal "sudo apt dist-upgrade".
- Once complete, reboot and enjoy!
As an add
Because Chromium is not available in the repos, an alternative is "ungoogled-chromium" available here:
https://software.opensuse.org/download/package?package=ungoogled-chromium&project=home:ungoogled_chromium
Which works well.
Have fun 🙂
