500 error trying to delete a host

Support
1

Well messing around with the pxe template being used by a host with
tokens enabled might have caused an issue.

I attempted to change the URL from the hardcoded form to the foreman_url
function (BTW thanks Greg for the suggestion), but changing that didn't
make the token string appear. Then I tried to put the old URL back with
the host.token function, which caused the token string to show up blank
in the preview. So I decided to delete the host and try again (worked
the first time I changed to using host.token), but now Foreman is giving
me a 500 error and doesn't remove the host:

Thoughts?

OK, I got around this by canceling the build process and "unmanaging"
the host. It then let me delete the system without issue. Sorry for the
noise.

If you take the system out of build mode, can you delete it?

sounds like a bug to me, that until build mode is toggled, the token
does not get deleted.

Thats exactly what I ended up doing. Stupid thunderbird not syncing all
of my folders. Sorry for missing your reply :slight_smile:

This is a known issue (Bug #3468: host deletion fails when token exists - Foreman) which
I'm currently working on fixing. Hope to have a patch by the end of the
week :slight_smile:
