I tried to install the Intel oneAPI toolkit (For using Fortran compiler) in the Ubuntu, by commanding
sudo bash l_BaseKit_p_2021.2.0.2883_offline.sh
After that, I checked that "Extract l_BaseKit_p_2021.2.0.2883_offline completed!"
and the
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
error has followed.
How can I fix this error?
