MAAS 2.5.2 released!


Hello MAASters!

I’m happy to announce that MAAS 2.5.2 is now available.

PPA’s Availability

MAAS 2.5.2 is currently available for testing in ppa:maas/stable for Bionic:

sudo add-apt-repository ppa:maas/stable
sudo apt-get update
sudo apt-get install maas

NOTE: Please note that MAAS 2.5.2 has now replaced 2.5.1 in the PPA.

Important annoucements

MAAS 2.5.2 introduces an important fix that address an issue where MAAS would create StaticIPAddress records with a NULL ip address. This was caused by DHCP updates (from a MAAS managed DHCP) not correctly updating the correct DB record, and instead, creating these new StaticIPAddress records.

As part of the fixes, a migration has been introduced to clean-up these NULL records to increase performance. If you encounter an issue in the upgrade process, please do file a bug report and comment on this post to investigate.

Relevant bug reports are: #1816452, #1817056 and #1817305.

The github repo ( doesn’t have the 2.5.2 tag. It’s just a tagging issue or means that the repo is outdated?


The github repository is indeed out-of-date, as development happens over on Launchpad. The github repository is just a mirror whiche out-of-date. may b:
