Ubuntu VM on Parallels M1 does not boot after upgrade

So I upgraded a VM running on Parallels on my M1, only to be greeted with:

This issue seems not to be unique to Parallels. It also happens with UTM. The quick fix here was to boot the machine with the previous kernel and customize grub to boot using GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true for as long as the issue persists.

Granted this does not work when trying to install from an Ubuntu 20.04.4 ISO image, but you can start from an older one for as long as the issue persists.

Update: kernel

Linux upwork-box 5.4.0-105-generic #119-Ubuntu SMP Mon Mar 7 18:50:13 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux

seems to work

Canceling all Jenkins jobs in queue

This is a continuation from a previous post where I showed how to disable all configured jobs in a Jenkins server (when for example launching a copy for test purposes). To this end, it may be the case that you have placed your Jenkins controller in quiet mode to have some ease of mind examining what goes on with your queue, or you simply want to cleanup the queue and have the system start with no jobs submitted. Whatever the reason, if you need to erase all of your Jenkins queue, python-jenkins and a few lines come to your assistance:

import jenkins

server = jenkins.Jenkins('http://127.0.0.1:8080/',
        timeout=3600,
        username=USERNAME,
        password=PASSWORD)

queue_info = server.get_queue_info()
for i in range(len(queue_info)):
    print(queue_info[i]['id'])
    server.cancel_queue(queue_info[i]['id'])
