I always prefer manual partitioning. If you have a separate /home partition you can reinstall the system without overwriting /home.

This is what I have now after re-installation
. Seems to be what you suggested (has one less partition than before). Does it look OK now?
It looks OK. Me I prefer the manual approach as outlined reasons in my previous post.
No. Simply take ''Erase disk'' and the Installer makes all automatically. You would only have to do that if You choose the 'Something else'' Option and You would create the Partitions manually.
Yes, that looks good so.

And don't get me started on Backup, DejaDup, Duplicity...
Which bits do I leave and which change and to what? What are the different colours?
Is there a handy list of these Ctrl +key things?
I think you can see them next to the options, or if you hover your mouse over them for a couple of seconds.
But I also just found this, seems up to date:

OK. First up, open a terminal and enter:
sudo nano /etc/cron.daily/trim
Next copy all of that text into the newly created text file.
The colours there are created to identify the elements in that line. If I enter a command on this forum, it too adds colours such as:
sudo lshw -C network

What do I do with the file?
Edit. I've managed to do a manual trim, involving becoming a superuser (something else I had to look up!)

You save the file by pressing Ctrl+ O, then Ctrl+ X to exit.
I've created the script, but how do I do the next steps? Sorry to be a pest
Through a terminal window (you can find "Terminal" in the applications menu). Enter each command one at the time (each line here is a different command):
chmod +x /etc/cron.daily/trim
systemctl status cron
systemctl start cron
systemctl enable cron

I tried using tom and it said it wasn't allowed. I then tried root and get this
root@OldMesh:~# chmod +x /etc/cron.daily/trim
root@OldMesh:~# systemctl status cron

What do I do then?
That looks normal to me, it means that the service is running. I guess the confusion is that that second command to check the status does not automatically exits back to the command prompt? Just type Q to exit that pager.
You don't need to run the other two commands, by the way, this already shows that cron is active and enabled.

Do I just ignore it now and it trims on its own?
If so, how do I turn it off?
That should be enough, yes. To turn it off, you can remove the executable bit from that script:
sudo chmod -x /etc/cron.daily/trim
Or move that file out of that folder.
