I read it as they are having trouble making the computer usable now.

My mind automatically interpreted that spelling as "unstable". It turned out that "unusable" matches the context better.

Ah yes I meant unstable

I blame the flickering screen for the typo.

I had to downgrade to 33 which was slightly annoying but no harm done. I guess I will skip this upgrade cycle and wait for 35

well trust me, what you originally wrote would be a funny story.

"broken computer got more usable, by installing broken software".

and it would probably be funny to debug that! Ü
