Hi @r00ta @troyanov @all

I have settedup a simplestream server for storing images and i can connect it from my MaaS server also. But I cant see any images that i installed on the simplestream mirror server.
Below is the command I used to pull the image.

sudo sstream-mirror   --keyring=/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg   https://images.maas.io/ephemeral-v3/stable   /var/www/html/maas/images/ephemeral-v3/stable   'arch=amd64'   'release=jammy'   'version_name=20260130'   --max=1 --progress

And in maas I can see

 Showing images synced from http://<mirror-ip>/maas/images/ephemeral-v3/stable/

But not the images I downloaded.

Are you locally hosting them on an http server right?
I also guess that you updated your boot source url to point to your local one already.

What you may have missed is to do

maas $PROFILE boot-resources import

This will also refresh the images served by the boot source if necessary.

Hi @alemar99 I have both Ubuntu 22 & 24 images in my mirror server as you can see below output from both MaaS & Mirror server. I even used the command to import the boot-resources. Still I am not seeing any images on my GUI pulled from the mirror server.

Hi @akashram611 ,

can you please post the output of:

maas maasadmin boot-sources read

and

maas maasadmin boot-source-selections read <boot_source_id>

for the boot source related to your local mirror?

I guess you are missing to create a selection for the images in your local mirror

You have to create a selection for jammy as well:

maas maasadmin boot-source-selections create 2 os=ubuntu release=jammy arches=amd64 subarches=* labels=*

And then import the images

maas maasadmin boot-resources import
