Reverting to Jammy Jellyfish

 Ever since I upgraded my Lenovo Ideapad from the previous version of Ubuntu, Jammy Jellyfish, to the newest version, Noble Numbat, I've been having a few stability issues with previously well behaved applications such a FocusWriter crapping out on me, which was a bit embarrassing when you're in the middle of taking notes of a meeting.

Now what one wants out of a computer is stablity and reproducability, basically everything works all of the time and everything is predictable, ie always works the same.

And, for whatever reason, I wasn't getting that. 

So I decided to revert. Actually not quite true, I did wonder about migrating the box to Lubuntu, but as the current version with a non beta window manager is built on Noble Numbat, that didn't seem such a good idea.

On balance reverting to Jammy Jellyfish seemed the better idea as all the instability issues came after I upgraded to Noble Numbat.

I had a look at the data on the machine, and there wasn't actually that much that hadn't already been copied elsewhere, so I transferred the last few items to Google Drive and then went for the nuclear option of completely wiping the machine and doing a complete reinstall from a freshly written USB.

After the install, after having gone through the Intel security chip shenanigans, I simply reinstalled my apps and copied my data back, including my Notable notes, and away we went.

Took me about an hour - actually a little longer as I had lunch in the middle of the exercise. 

The only way I'm going to find out if the stability issues have gone away is to use the machine, and twenty minutes writing a blogpost doesn't really count, but hopefully a few days use will convince me that I've a stable system again...
