Solutions
Before installation of the software, please visit the vendor web-site for more details.
For Ubuntu
The problem can be corrected by updating your system to the following package versions:
- Ubuntu 16.04
- Ubuntu 18.04
- Ubuntu 20.04
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
For SUSE
Apply fixes issued by the vendor:
- SUSE Linux Enterprise High Availability 15-SP3
- SUSE Linux Enterprise Module for Basesystem 15-SP3
- SUSE Linux Enterprise Module for Development Tools 15-SP3
- SUSE Linux Enterprise Module for Legacy Software 15-SP3
