Web UI does not work from default install (2.1.0~bzr-2009-0ubuntu1)l

This bug was fixed in the package cobbler - 2.1.0-0ubuntu1

---------------
cobbler (2.1.0-0ubuntu1) natty; urgency=low

  * New upstream release.
  * Make it a bit more easier to configure cobbler_web (LP: #741661)
  * Drop java dependencies since cobbler4j is no longer shipped upstream.

Hmm, there's a bit more work to be done on this bug.

 1) I still had to edit cobbler_web.conf and comment out:
 #CustomLog logs/access_log combined env=!dontlog

 2) The symlinks in cobbler-web.postinst all need to be "ln -sf", or else upgrades of the package will fail.

 3) I still had to edit /etc/cobbler/modules.conf and set:
  module = authn_configfile

 4) I still had to add users to /etc/cobbler/users.digest and restart.

I have a patch that solves most of this.

Hi Jamie,

Would you mind giving the latest cobbler packages in this PPA a try, and reporting back? Thanks!!!

Hi Dustin,

Just wanted to report that the issues are resolved in the cobbler package from your PPA, but the one in the PPA also introduces new bugs with viewing kickstart and snippet files ("CX: tainted file location" exceptions):

Is the plan to move your package into the cobbler tree, or will you just submit a patch to the post-install scripts for the current cobbler-web packages?

Hi David,

Thanks for testing. Do you have any idea what that error/fault means?
 I'm unfamiliar with it.

Also, is this a 'regression' with the new upload? Or just a new issue
in that we're getting further into cobbler functionality now? ie, I
would like to upload what we have now, and continue burning down
issues like this incrementally, assuming that the current upload
hasn't actually *caused* this regression...

I suspect that this might have something to do with file and directory
permissions in /var/lib/cobbler/somewhere. Something probably needs
to be chmod'ed or chown'ed to www-data.

Hi Dustin,

Just in the process of testing on a fresh Natty install. I'll snapshot my VM and try the same process with the ubuntu2 packages from natty and then again with the packages from your PPA and confirm.

Judging from this:

http://<email address hidden>/msg01200.html

I believe it is an issue with the latest upstream source. It appears to have happened around the same time they moved to a form-based Authentication for the login to cobbler_web.

More results to follow.

Cheers,
David.

Just noted in the cobbler-devel lists this message:

http://<email address hidden>/msg01202.html

"commit 41a92b11969ab9c30b749ab99be70566cd943093

    Fix for snippet/kickstart editing via the web interface, where a
'tainted file path' error was thrown"

Seems to have been a dormant bug that didn't rear it's ugly head until they did some unrelated changes. Apparently patched though, so perhaps you could apply said patch and re-post some packages for testing?

Cheers,
David.

Just to confirm, this is a regression with the new upload in your PPA, as the ubuntu1 packages (the ones that didn't setup the webUI correctly) did not exhibit this issue.

Seems to be an upstream regression though.

OK, just to clarify a bunch of stuff:

1) The original cobbler-2.1.0-0ubuntu1 packages worked once you reconfigured the the cobbler_web.conf and re-created the symlinks

2) The cobbler_web.conf is /NOT/ fixed in cobbler-2.1.0-0ubuntu2. With this package I still had to change the authz_configfile setting in modules.conf and `chown www-data:www-data /var/lib/cobbler/webui_sessions` before I could login.

3) Using the package in your PPA (cobbler-2.1.0-0ubuntu3~ppa1) the install completes fine and the web-config is working out of the box.

** BUT **

The new bug concerning "tainted file location" errors now exists in both the PPA:cobbler-2.1.0-0ubuntu3~ppa1 and cobbler-2.1.0-0ubuntu2 (current in Natty).

I'll raise a new bug for the "Tainted File Location". If you merge your changes for the postinst/postrm and config files that should resolve this bug.

There is a patch for the new bug, but that can be discussed separately.

Cheers,
David.

Once the PPA postinst/postrm stuff is merged from Dustins PPA (https://launchpad.net/~ubuntu-virt/+archive/ppa) package the original bug (#741661) with cobbler-web installs not working out of the box will most likely be resolved.

This bug was fixed in the package cobbler - 2.1.0-0ubuntu3

Possible regression with 2.1.0-0ubuntu4. I had to comment out the CustomLog lines in cobbler_web.conf before Apache would start. I will try and confirm, but at this stage my system has had a million different versions of cobbler installed over the past 2 days, so I can't be sure.

Will try on a fresh system and let you know.

Cheers,
David.

Confirmed that a fresh install of Natty +

apt-get update
apt-get dist-upgrade
apt-get install cobbler cobbler-web

Still has a non-working web config. Apache fails to start with:

"[error] (2)No such file or directory: could not open transfer log file /etc/apache2/logs/access_log"

The fatal line in /etc/cobbler/cobbler_web.conf is:

9:CustomLog logs/access_log combined env=!dontlog

Commenting out this line fixes Apache startup, but i prefer to change the access log to be something more sensible, like:

CustomLog /var/log/cobbler/web_access.log

Scratch that... the packaged version is still cobbler-2.1.0-0ubuntu2 in the repos. The patches in cobbler-2.1.0-0ubuntu4 source have fixed all of the above issues.

The new one should land very shortly. It was held up because Andres
introduced a new python-koan binary, and we needed an archive admin to
approve the new binary.

not able to see web_ui even after following above stpes in ubuntu 12.04

When I run http://<myip>/cobbler_web

error is "Internal Server error"
