Think I can see what happened.
Two versions are pushed on the same day, with the same tags.
The old version gets untagged, and is garbage collected

I got the /etc/hostname error on my distrobox upgrade in Bluefin LTS, so it's not just F42, this thing is coming from somewhere

tulip•4/28/25, 4:35 PM

what im thinking of is either distrobox or podman being weird

tulip•4/28/25, 4:36 PM

nothing seems to be radically different on the image itself

tulip•4/28/25, 4:36 PM

maybe that hostname file gets made on

podman build

podman build

time?

The Renovate digests issue is exactly this. Made Timothee aware, and I'll try to push a fix to gitlab in the next couple days

M2•4/28/25, 5:04 PM

Oh he doesn't make sure to make a new version tag....

M2•4/28/25, 5:04 PM

You could probably steal the skopeo list-tags loop

j0rge•4/28/25, 5:25 PM

no just users complaining

89luca89•4/28/25, 5:31 PM

it happened on my centos machine too so it's not just F42

j0rge•4/28/25, 5:44 PM

ok so my 42 machine has a hostname but my LTS one does not.

j0rge•4/28/25, 5:45 PM

if we touch an empty hostname file if it's missing that seems to solve the issue

RobertOP•4/28/25, 5:46 PM

The issue I believe is if you create a Distrobox while there's an os-release present, then update the host to an image which remove it, the container fails to start up

j0rge•4/28/25, 5:46 PM

update the host to remove what?

RobertOP•4/28/25, 5:47 PM

Perform an update on the host. A recent report said rolling back to a previous update restored the file

j0rge•4/28/25, 5:47 PM

yeah I can't replicate on my F42 machine

j0rge•4/28/25, 5:47 PM

but my LTS machine is missing the file

j0rge•4/28/25, 5:51 PM

Oh interesting!

j0rge•4/28/25, 5:51 PM

the machines are DX only

M2•4/28/25, 6:20 PM

i do not have an /etc/hostname

M2•4/28/25, 6:20 PM

M2•4/28/25, 6:20 PM

No static hostname

M2•4/28/25, 6:22 PM

I believe instead its getting the default hostname from

/etc/os-release

/etc/os-release

sgtm, does anyone hate this?

j0rge•4/28/25, 6:30 PM

can we toss this in one of the service packages so we can fix lts and bluefin in one place?

M2•4/28/25, 6:32 PM

The only thing weird is if a user is truly using dhcp for setting hostnames. I would maybe add a stamp file instead for the conditions check

RobertOP•4/28/25, 6:33 PM

Do they not have /etc/hostname files? Or does their

hostname

hostname

not return what DHCP assigned?

RobertOP•4/28/25, 6:33 PM

I would expect

$ hostname

$ hostname

to always give the desired name, which is what the %H does

M2•4/28/25, 6:34 PM

i have no idea what takes precedence. If /etc/hostname or a transient hostname

M2•4/28/25, 6:34 PM

as in we are making a transient hostname static by writing it to /etc/hostname
