Re: [HTCondor-users] HTCondor on Ubuntu 12.04


I wonder what kind of progress has been made, if any, getting condor_compile on Ubuntu 12.04? And, with release 2 months way, is 14.04 support of any kind being considered?

You're opening a bit of a can of worms owing to the different kernel versions one could be running under an Ubuntu LTS release (with "hardware extensions" enabled 12.04.3 could be running any one of 3.2,3.5 or 3.8). This matters for condor_compile, right?

To me, the simplest thing to communicate to user might be "we'll only support the initial (GA) kernel release" (*) or the "we'll only support the latest kernel release" or "we won't officially support condor_compile".

(*) The way kernel releases occur, if you install with the 12.04.3 install DVD you will end up with the latest kernel (today: 3.8), while if you download a copy of the 12.04 initial release DVD and only do an apt-get dist-upgrade you will end up with the initial GA kernel release (today: 3.2). It's reasonably easy to upgrade/downgrade kernels, but the mechanism of updating the install ISOs means you'll almost certainly be supporting a heterogenous group of users.

It appears that there is demand for running HTCondor on Ubuntu 12.04 (Precise Pangolin). Previously, users have been using the Debian package on Ubuntu without difficultly. However, since the advent of python bindings, the HTCondor .deb will not install cleanly on Ubuntu 12.04 because of the different versions of python installed between Ubuntu and Debian.

We plan to support Ubuntu 12.04 in the very near future. As an interim measure, I have put .deb files and tarballs for Ubuntu 12.04 on our download site for HTCondor versions 8.0.2 and 8.1.1. These builds are made for our internal build system. So, they are exercised quite a bit. They do not have all features of HTCondor enabled. These builds do not support the 'standard universe' which provides transparent checkpoint and migration. However, the packages will install cleanly on Ubuntu 12.04.

Consider these files to be a preview into Ubuntu 12.04 support.

Any comments and feedback are welcome.

A thought: although it's not advertised in the front page at http://research.cs.wisc.edu/htcondor/debian/, I discovered there is now a Debian Wheezy package available in the repo.

This *does* seem to install under Ubuntu 12.04 just fine (I tried it with 8.0.2, which is the latest available in the repo). It has a dependency on libpython2.7 (>= 2.7). I haven't tested that it works properly, other than restarting condor.

So whilst a supported package and repo specifically for Ubuntu would be great, maybe we can live without for now.
