Should I use an older version of kubeshark? Would you please provide me with a compatible version number？(For some season it is forbbiden to upgrade my Ubuntu kernel version.)

[Buenbk]

I downloaded version 41.2, but why does it show version 51.0.27?
curl -Lo kubeshark https://github.com/kubeshark/kubeshark/releases/download/41.2/kubeshark_linux_amd64 && chmod 755 kubeshark

./kubeshark tap

[Buenbk]

I have try some older versions, but none of these can be successfully installed in Ubuntu 18.04.6.
