EOS client availability for Ubuntu 22.04 Jammy Jellyfish


Ubuntu has released new LTS 22.04. Do you think it would be possible to build a client for this release?

Thank you,

Hi Rustem,

Yes, we plan to support Ubuntu 22.04. We expect to have a client release ready in the next period.
I will let you know once this is done.


I’d be very interested in this as well. Do you have an estimate when we’ll have it ?

Hi Ulrich,

For the moment there is no XRootD release for Ubuntu Jammy due to some build issues. Once this is fixed we will also release EOS for Ubuntu Jammy. At this point I can not give you an estimate when this will happen.


it seems as if xrootd and friends are available now for Jammy Jellyfish. It would be really nice to have eos-client as well if possible! Thanks a lot!

Hi Ulrich,

Indeed xrootd will start to provide builds for jammy, and we are already preparing as well!

Although I believe it will only be available once we tag with xrootd 5.5.0 requirement.


Hi, do you have an estimate about when this may become available ? Thanks a lot!


Yes, once XRootD 5.5.1 [1] is out it will also provide Ubuntu Jammy packages and then we’ll have an EOS client release also for this distribution. I would say in maximum 2 weeks.

Thanks for the update! Works for me.

Ubuntu 22.04 for the eos client are now available here:

Hi, worked fine until a few day ago when apt decided to upgrade xrootd to 5.5.2 and junked eos-client and fuse-x because they requires 5.5.1. I cannot see the xrootd 5.5.1 packages in the repo any longer thus downgrading doesn’t work either. Any chance to have the eos packages rebuild ?

I encountered the same problem. The previous workaround to pin the correct version worked:

echo -e "Package: xrootd* libxrd* libxrootd*\nPin: version 5.5.1\nPin-Priority: 1000" | sudo tee /etc/apt/preferences.d/xrootd.pref
sudo apt update
sudo apt upgrade
sudo apt install eos-fusex
