Hi Hernán, H> Hi, Inadvertently during installation I chose CentOS 7 as my edge H> platform and installing the QluMan GUI proves to be difficult on H> CentOS 7 due to missing Qt dependencies. Now I am stuck trying to H> install an alternative platform: H> root@plato:~ # schroot -l chroot:centos7 root@plato:~ # H> chroot-centos7 (centos7) root@plato:~ # yum update yum install H> qt-10 qt5-qtbase-devel mesa-libGL-devel mesa-libGLU-devel yum H> install qluman-qt Loaded plugins: keys, post-transaction-actions, H> protectbase 0 packages excluded due to repository protections H> Resolving Dependencies --> Running transaction check ---> Package qluman-qt.noarch 0:10.1.0.37-1.ql.el7 will be installed --> Processing Dependency: qt-10 = 10.1.0.37-1.ql.el7 for package: H> qluman-qt-10.1.0.37-1.ql.el7.noarch --> Finished Dependency Resolution H> Error: Package: qluman-qt-10.1.0.37-1.ql.el7.noarch H> (qlustar-10.1) H> Requires: qt-10 = 10.1.0.37-1.ql.el7 H> You could try using --skip-broken to work around the problem You H> could try running: rpm -Va --nofiles --nodigest the easiest way to use qluman-qt is to use the singularity image on the Qlustar download page. You can do this on any Linux workstation where a new enough singularity package is installed. H> I couldn't find how to install additional edge platform for my H> chroot environment **without** requiring QluMan, in the H> documentation : https://www.qlustar.com/book/docs/install-guide : H> "Note that you can always add support for a previously unselected H> edge platform later on by creating corresponding chroots and H> Qlustar images using QluMan." H> Is there an alternative way to add a platofrm without requiring H> the QluMan GUI? No. H> Is better to re-run the initial config again?

Anyway it's not critical, just a script to setup convenience functions for running the Linpack as described in the 'First Steps Guide'. You can try to execute the following as your user on a compute or the FE node which will have the same effect: $ /usr/lib/ql-hpl-tools/install-qsub-func.sh H> But no problems so far. Good news.
