gvm-libs version 11.0.1 - Severity 10 due to end of life Scan Engine

[devMarc5598]

Hi everyone,
how can I update my gvm-libs version or container to the latest version?
I currently using the OpenVAS gvm-libs 11.0.1...

In my current Scan-Reports i get this Vulnerability:
“Report outdated / end-of-life Scan Engine / Environment (local)”
It says that my currently installed GVM Libraries (gvm-libs) version is 11.0.1 and that I should update the gvm-libs to the latest available GVM Libraries version 20.8.0.

GVM versions:
gsad: Greenbone Security Assistant 9.0.1
gvmd: Greenbone Vulnerability Manager 9.0.1
openvas-scanner: OpenVAS 7.0.1
gvm-libs: gvm-libs 11.0.1

Environment:
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
