I’m doing software development on an Ubuntu 20.04 VM running on my MacBook Pro via Parallels Desktop 17. I recently noticed that the “Software Update” app in the Ubuntu desktop machine was saying there were a lot of things to update, which makes sense since I just created this VM a couple of months ago via a fancy Ansible playbook, and I haven’t gotten around to updating it until yesterday.
Well, after the update, it started taking a really long time to boot. There were two places where it hangs for 2 minutes for no apparent reason, meaning that the boot process is about 4-1/2 minutes long.
I’ve figured out what happened and found a workaround, but I’ll mention a few of the things I looked at along the way since they’re sort of interesting and may be relevant if your issue is similar but not caused by the same thing.

Argh! I spent about 5 hours yesterday troubleshooting a failed Ubuntu Jaunty -> Karmic (9.04->9.10) upgrade. It worked fine until I rebooted and then failed to boot. Here’s how I fixed it.

Once again Ubuntu Linux proves itself to be easy to upgrade. Going from 9.04 to 9.10 (one release newer, since their numbering is bsaed on dates) was easy, but included the standard sprinkling of manual re-customization that I’ve come to expect from Debian based systems.

I’m working on a Rails app that uses the ym4r_gm plugin, getting Google to do the geocoding for Thentic. I liked the idea of stubbing the web service call, because all those calls to an external service add up to over 20 seconds of test suite run time(!). That’s almost half of the 50 second run time of my unit tests (and 50 seconds is much too long for a unit test suite).
I found a good starting point at geokit stubbing for faster tests. I also wanted a way to stub a geocoding failure, and a way to prevent any unit tests from using the real geocoding web service.
Here’s how I did it.

I’m at WordCamp San Francisco today and decided that running a year old version of WordPress (on a year old version of Ubuntu Linux) was undesirable. So, with the confidence that comes from many relatively easy Ubuntu OS upgrades, I charged ahead. For (I think) the second time ever, things went badly. Here’s what I did and how I fixed it.
