ohpc: Problem and solution to issue when using EasyBuild with Xvfb eb files

Hello

I have recently had a problem when I was trying to install Xvfb-21.1.6-GCCcore-12.2.0 using EasyBuild 4.7.2. When I was trying to install this using Xvfb-21.1.6-GCCcore-12.2.0.eb (/opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/Xvfb-21.1.6-GCCcore-12.2.0.eb), I got an error where the checksum for the patch for xvfb-run was not correct:

[rocky@rockygpu Gaussian_test]$ eb Xvfb-21.1.6-GCCcore-12.2.0.eb --robot --parallel=4

I looked for this checksum in the Xvfb-21.1.6-GCCcore-12.2.0.eb file and found this is associated to a patch file called xvfb-run. I did some investigating and found that if I ran eb --search Xvfb, there was an entry for xvfb-run:

[rocky@rockygpu ~]$ eb --search Xvfb
== found valid index for /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs, so using it...

 * /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/xvfb-run

I ran the checksum for the entry for xvfb-run:

[rocky@rockygpu ~]$ sha256sum  /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/xvfb-run
a70efee6934d53d7c228a4a8b2a7966b6eb4b47203d66818f122c66b1ab4e7c0  /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/xvfb-run

and changed the checksum currently in Xvfb-21.1.6-GCCcore-12.2.0.eb with this one:

    (name, version, {
        'source_urls': ['https://www.x.org/releases/individual/xserver/'],
        'sources': ['xorg-server-%(version)s.tar.gz'],
        'patches': [('xvfb-run', '.')],
        'checksums': [
            '6f9c73ccc50e2731adac17671c8e33687738c8cd556b49ecb9f410ce7217be11',  # xorg-server-21.1.3.tar.gz
            'a70efee6934d53d7c228a4a8b2a7966b6eb4b47203d66818f122c66b1ab4e7c0',  # xvfb-run  # <-- this is for the checksum when running "sha256sum /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/xvfb-run" . original checksum sha256: 'fd6d13182b77871d4f65fccdaebb8a72387a726426066d3f8e6aa26b010ea0e8'
        ],
        'start_dir': 'xorg-server-%(version)s',
        'configopts': local_xvfb_configopts,
        'buildopts': local_xvfb_buildopts,
        'installopts': local_xvfb_buildopts,
    }),

and then retried running eb Xvfb-21.1.6-GCCcore-12.2.0.eb --robot and this seemed to do the trick.

I assume that the /opt/ohpc/pub/libs/easybuild/4.7.2/easybuild/easyconfigs/x/Xvfb/xvfb-run has been updated recently but the checksums for this file in the Xvfb eb files have not been updated.

I also tried installing Xvfb-21.1.3-GCCcore-11.3.0.eb (eb Xvfb-21.1.3-GCCcore-11.3.0.eb --robot --parallel=4), got the same problem, and the same solution fixed this. I assume this will be a problem for all the Xvfb eb files.

I didnt know where to update this code in this github directory, so I thought to added it here as an issue. Hopefully this helps sort the problem out 😃

I have attached my updated Xvfb-21.1.6-GCCcore-12.2.0.eb and Xvfb-21.1.3-GCCcore-11.3.0.eb files here.

Xvfb-21.1.3-GCCcore-11.3.0.eb.txt Xvfb-21.1.6-GCCcore-12.2.0.eb.txt

Thanks for all the work. Setting up a HPC and OpenHPC is great!

Kindest regards,

Geoffrey
