Can my 15.5 to 15.6 DUP be saved after hanging near the end

I started a zypper dup process to upgrade from leap 15.5 to 15.6. I broke the process down into steps with logs at each step. The preparation and setup steps worked fine as far as I can see.

I made a Request.

Sorry. Found out after I posted. Fixed links in Post 3

Hardware lists are short enough to copy and paste here directly.

Please describe here what you last saw before the “hang”. What to you does “hang” mean, and its consequences for purposes of this thread?

The DUP was running in a ROOT terminal (ctrl+alt+F1) as displayed in the log 04-zypper-dup-run.txt. It had nearly reached the end of the process -
(2250/2273) Removing: python3-qt3d-qt5-devel-5.15.6-bp155.1.8.x86_64 […done]
(2251/2273) Installing: yast2-samba-client-4.6.1-150600.1.2.noarch […done]
(2252/2273) Installing: yast2-ntp-client-4.6.0-150600.1.3.noarch […
The hangup was during line 2252 trying to install yast2-ntp-client. Processing just stopped. I waited for quite some time and pressed ctrl+C to cancel the process. This resulted in zypper saying it was trying to gracefully terminate and another long wait. I pressed ctrl+C again which resulted in another “cleaning up” message. There was some sort of processing going on as the disk activity light would occasionally flash so I left running it overnight.
This morning I tried ctrl+alt+F7 and the system returned to KDE where I found thing pretty much accessible except for no access to the internet. I have not attempted a reboot.

What error(s) result when you attempt internet access, such as zypper ref or pinging your ISP? Does /etc/resolv.conf exist and point to a sensible location? What does ip a report?

Zypper fails due to no net access.

Please always provide error messages, along with whatever command created them, not summaries of what you saw.

You apparently have an IP assigned, but didn’t report on /etc/resolv.conf. If it’s OK, it may be a that your firewall is running but not configured to allow anything through it. Try turning it off until you know zypper has finished its job.

The firewall was apparently the issue. I am now able to access the internet, ping various sites, run zypper refresh and run my browser (firefox).

Should I attempt a restart of the DUP process using the same command line?

echo 'zypper -v --releasever 15.6 dist-upgrade --allow-vendor-change --allow-downgrade' >04-zypper-dup-run.txt
date | tee --append 04-zypper-dup-run.txt

After restarting the zypper DUP process I am now on 15.6.
This problem is now solved.
