For anyone that’s just looking for a one-liner to run and resolve this issue, here you go:
sed -i"" 's/GSA_MAJOR="21.04"/GSA_MAJOR="21.4"/g' $(which gvm-check-setup)
Are there any plans to fix this from the actual source? I have this automated installation process built into a Docker process that spins off every once in a blue moon. Just trying to see if I should be waiting for an official fix or if I need to create a quick sed workaround to replace this.
