Hello, thank you for your answer!

I tried to upgrade packages with OMEdit but the operation fails due to the error in red:

However Openmodelica seems to work fine.

Hello,

I'm working on a project which uses Openmodelica 1.16, that it was installed on my system RHEL8 and everything was working fine.
After the last updates the Openmodelica installation was broken, so I tried to reinstall it (https://build.openmodelica.org/rpm/el8/), but I can't due to this error:

"nothing provides omlib-all needed by openmodelica-cpp-1.16-1.16.5-2.el8.x86_64"

I tried to manually install omlib (https://build.openmodelica.org/rpm/omlib/) with no success. Can anybody help me?
