I ran into something similar on Linux Mint. Never seen my installation kill itself before until this. Ended up booting into Recovery mode from the grub menu, and rolled back using Timeshift restore.
For me, the culprit was the ubuntu-drivers-common
update, because after I rolled back, I was able to install all the other updates without issue. I just blacklisted this one update to keep it from showing until the next version is released.
Ah, the Pinterest strategy. Nothing makes me hit the back button or skip search results faster than a login prompt.
I wonder if this is just a ploy to increase their “active user” counts to improve their valuation.
Did you read the bill? This is in the first paragraph.
