Failed to upgrade Linux kernel to 4.0.15-194 on ubuntu 18.04 running on Hyper-v

gg flag

I have a windows machine running with Hyper-V running Ubuntu 18.04 32Bit. The Linux kernel version is : 4.15.0.91-generic. When trying to upgrade to the recent kernel. 4.15.0-194 it ends but fails to restart. The last message shown is:

Started update UTMP about System Runlevel Changes....el crash signature

Since this is Hyper-c machine so I use the option "revert" to the last VM checkpoint, but I prefer to get the main stream updates instead of cherry picking patches.

So the titel should be "kernel to 4.0.15...", not from? However - how does it fail to restart? Have you interrupted the boot process to modify the bootline of grub, to change `quiet splash` to `noquiet nosplash` to read the messages? Did you update via `apt` or how did you do it?

Initially I did the update using the `apt` but then after fail I used the "Software updater" tool in order to custom which is the update that failed the boot.

That's a lot of information, which excludes some premature guesses. I hope it helps someone else.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
