MAAS 2.7 - UI issues

Hi All,

We are currently performing some acceptance testing on MAAS 2.7 prior to our migration from 2.6 and we’ve hit a couple of issues.

  1. The UI often hangs (especially on the machines tab), there can be a wait of 10 seconds before the UI becomes responsive again. Other times the browser will present a dialogue stating the page has become unresponsive. We’ve profiled the machine and it’s not in the slightest bit busy. This is an out of the box config.

  2. The system does not deploy the selected OS. We tend to use Ubuntu 18.04 LTS and 20.04 LTS, and when we select 20.04 to be installed 18.04 is deployed. We have changed to the default OS to ubuntu 20.04 and it still installs 18.04

In general we’ve had a really good experience with 2.7, but the two issues above are holding up our adoption of this version of MAAS.

Best regards,

Hi @joolski,

I’m terribly sorry to hear you’re hitting these issues. We’ve been working on improving both of those for the upcoming release of MAAS 2.8 - may I suggest you try out the beta of 2.8 instead of 2.7?

You can install it with:

sudo snap install maas --channel=2.8/beta

And if you hit any issues, we’d love it if you share them either on here or by filing a bug directly.



Hi Lilyana,

Thanks for the response, we’ll try out the 2.8 beta and give you some feedback.
Is it possible to upgrade an existing 2.7 installation to 2.8 bata ?

Best regards,
