OpenVAS Scan failed (RHEL 8)

[HarunaMurata]

I have OpenVAS 21.4.0 installed on Red Hat Enterprise Linux 8.
I have been running SCAN regularly, but half a year ago it suddenly became impossible to SCAN.
The thing that comes to mind is an update of Red Hat Enterprise Linux 8.
The logs show the following.
Manual scans also resulted in the same error.
Please let me how to isolate the problem.

This month's regular scan also failed with the same error.
Is anyone else having the same problem?

There are some updates coming up in the atomic-testing channel, do you think you can try these out to see if they cover it? You can upgrade with:

yum --enablerepo=atomic-testing update

[atomicturtle]

These packages have been published to the atomic repo, let us know if you're still having a problem otherwise we'll close this one out shortly

[HarunaMurata]

Thanks for your update.
I will update the package as suggested.
However, when I run the command I get the following error.

---

yum --enablerepo=atomic-testing update
Updating Subscription Management repositories.
Error: Unknown repo: 'atomic-testing'

---

I don't know the cause of the error, is it a problem in our environment?
