Details of upgrade packages and install one at a time

Caution: Inexperienced user, Kubuntu 18.04 LTS

I'm trying to track down a problem and have restored my system to a non-problematic backup on 18 March. This gives me a list of 219 updates available in Discover.

What I want to do is install each update as they were released. I can get:


udo apt-get update >updatelist19Jun20.txt


Hit:1 http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu bionic InRelease
Hit:2 http://gb.archive.ubuntu.com/ubuntu bionic InRelease
Hit:3 http://gb.archive.ubuntu.com/ubuntu bionic-updates InRelease
Hit:4 http://gb.archive.ubuntu.com/ubuntu bionic-backports InRelease
Hit:5 http://security.ubuntu.com/ubuntu bionic-security InRelease

I don't know how to check details and install each one, and in any event I suspect they are not in date order.

My plan is to install one batch at a time and check if my problem occurs. That at least will help me narrow it down to what might be causing the problem.

If I find a set up updates that do cause a problem, then how do I backtrack?

I'm guessing here, but have you tried:

sudo apt-get update <a file from updatelist19Jun20.txt>

Depending on how many upgrades there have been you can see probably a large majority of them, if not all by running
grep -i " upgrade " /var/log/dpkg.log.1 /var/log/dpkg.log which will list all upgraded packages by date and time. This should allow you to figure out which day each of the upgraded packages arrived with you.
