I upgrade ubuntu 18.04.1 to 18.04.2 by software-updater.
I met some trouble, and may be cleared.

1. snapd.sap-repair.service is a disabled or a static unit, not starting it
    <https://askubuntu.com/questions/1037431/receiving-the-error-snapd-snap-repair-service-is-a-disabled-or-a-static-unit-n>

    My PC is ASrock H110M-HDV(vga on board), Intel i3-7100, nvidia 1050-Ti, UEFI using CSM, MBR disk, others.
    I use 1050-Ti to GPU, not using VGA card, so I do not connect display.
    I modify /etc/modprob.d/bloacklist.conf to add nouveau, then this error not occur software-updater
   that upgrade ubunut 18.04.1 to 18.04.2. then linux kernel 4.15.0-46-generic

2. rboot ubuntu 18.04.2, PC may freeze

    ubuntu-18.04.2 update finished, but reboot PC, could not start ubuntu-18.04.2.
    but power off/on operatiion, PC boot up and start ubuntu-18.04.2

    I install 18.10 kernel and xstack environment.
    sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

I add comment.

first I think PC environment problem example UEFI, BIOS, MBR, GPT.
because UEFI + GPT and BIOS + MBR environment, not occur this problem.
Only UEFI using CSM + MBR environment occur this problem.
finally I found nouveau.

for blacklist.conf.
I added /etc/modprobe.d/blacklist-nouveau.conf.

# nvidia(nouveau)
blacklist nouveau
options nouveau modeset=0

then run command

sudo update-initramfs -u

Can you help with this problem?
