So, one of my main gripes about Ubuntu Mate 16.04 and 18.04 is that I have horrible download speed whenever dealing with a USB drive. (20-100k!) I know my hardware is ok because Windows can send a 700M file in about 20 seconds. Ubuntu takes 8-10 hours!
I did find a partial reprieve in that grsync would copy 1G in about 30 minutes but I had to put it in a file folder.
So, in reading about 18.10, it sounded like someone FINALLY fixed this problem that so many people have. So I upgraded to 18.10 and everything looked fine and worked fine UNTIL I tried to put a file on a thumb drive. Then all H-E-double hockey sticks broke loose. Caja locked up the entire system. I couldn’t do anything but move the mouse pointer. So I held the shutoff button for 5 seconds and re-booted.
I could not reboot. I kept getting to a screen that told me there were parsing errors and gave me an (intramfs) (sp?) prompt. If I typed ‘exit’ then it said I needed to fsck manually. I finally got that to work and came up with a couple of thousand errors, all of which I had to say 'Y’es to.
When I could finally get to my home screen, all of my settings were gone. All of my bookmarks in firefox and waterfox were gone. And now, everything keeps crashing. Kmail crashed, Plank crashed, Waterfox, Firefox, Caja, and on and on.
Now how do I go back?!
