    I just like to add that this has already happened to me with an Ubuntu
    20.04 LTS container running on
    SL7:

    [wgs34:U20] ~ % gnuplot-qt
    gnuplot-qt: error while loading shared libraries: libQt5Core.so.5:
    cannot open shared object file: No such file or directory

That doesn't have much to do with the container running on SL7, and more that your gnuplot-qt was compiled on a different qt5 than is in the container. Without more details I couldn't exactly say more than make sure your gnuplot-qt and qt5 libraries in yoru container are up to date.

Hi Troy,

it is related to the SL7 kernel. The container contains a standard Ubuntu 20.04 LTS installation with the default gnuplot package. The problem disappears when I run the same singularity container on AlmaLinux 8.4 or Ubuntu 18.04 LTS.
