USERTrust RSA CA certificate in old CentOS /Red Hat expired

This has become a problem for some people that has flexVDI installed on not updated CentOS / Red Hat < 7.8  machines. USERTrust RSA is the CA that signed the certificates in our web servers, including portal.flexvdi.com, which is used by flexvdi-config to download licenses, and updated releases of flexVDI manager.

When sysadmins try to connect to flexVDI portal using flexvdi-config, they will see an message like:


To solve this problem, just run in your flexVDI hosts:

# yum update -y ca-certificates


And flexvdi-config will work right again.

Released flexVDI agent 3.1.7

Fixes a bug in the creation of flexvdi manager that causes flexvdi manager to get a wrong clock time from the hardware clock when it is started, if the flexVDI Host is not configured in UTC.

The fix will take effect after updating the package, the next time flexVDI manager is started.

The new release can be updated executing in the flexVDI hosts:

# yum -y update flexvdi-agent
