I have been looking for several days for a stable version of Ubuntu Mate 18.04 Desktop which I will use on my Raspberry Pi 3B. In August, I was able to get Ubuntu Mate 18.04 from ubuntu-mate.org/download/arm64/ and it worked smoothly. Anyway I was trying to use my RPi with a robot and for some reason I lost my SD card and replaced it. Now I need the version I downloaded but I am not able to find it at the same place. 18.04 is removed and there are only 20.04 and 20.10.
I went through the "Browse Downloads" at the bottom of ubuntu-mate.org/download/ and reached releases.ubuntu-mate.org/archived/bionic/arm64. Anyway the image I downloaded and used (which is ubuntu-mate-18.04.2-beta1-desktop-arm64%2Braspi3-ext4.img.xz 24-Mar-2019 23:17) caused plenty of trouble and lost time to me. It required a partial upgrade (upgrade for more than 500 packages) and even after I solved plenty of problems it caused, it still gives errors.
Therefore, I believe this version is not the one I downloaded in August and used without any problem. I was wondering if anyone has the version I am looking for. I would be really happy if so.
By the way I checked Raspberry Pi for possible errors during robot installation, with several different SD cards and non gave any error. That is why I believe the Ubuntu Mate version I am using is the problem.
Thanks a lot in advance.
