BUG: unhandled scenario: current version: 1.12.0-rc0, latest version: 1.12.0

[didier-durand]

Hello,

After installation of kata, 'kata-runtime kata-check' now produces the following:

ERRO[0000] BUG: unhandled scenario: current version: 1.12.0-rc0, latest version: 1.12.0 arch=amd64 name=kata-runtime pid=7617 source=runtime
BUG: unhandled scenario: current version: 1.12.0-rc0, latest version: 1.12.0

My install via '$(curl -fsSL https://raw.githubusercontent.com/kata-containers/tests/master/cmd/kata-manager/kata-manager.sh) install-docker-system"' was repeatedly working just fine until the version 1.12 of the project was published 1 hour go.

Is there a workaround until you fix?

Thanks

DIdier

More information: kata-runtime seems properly installed as per below. Just 'kata-runtime kata-check' seems to fail.

'kata-runtime kata-env' produces

Hi @didier-durand - thanks for reporting. Please can you try running the following until we investigate and fix the issue:

$ kata-runtime kata-check -n

[didier-durand]

Thanks for this workaround! I get now the final sentence that I need.

Output:

kata-runtime kata-check -n
WARN[0000] modprobe insert module failed: modprobe: ERROR: could not insert 'vhost_vsock': Operation not permitted arch=amd64 error="exit status 1" module=vhost_vsock name=kata-runtime pid=11351 source=runtime

@didier-durand - I'm actually going to fix this in 2.0 first and as soon as that has landed backport the fix to the 1.x releases (here). The 2.0 PR is:

• release: Fix release candidate to major version upgrade check kata-containers#1105

[jodh-intel]

@didier-durand - it's worth pointing out that if you run sudo kata-runtime kata-check, it will perform a more comprehensive check (and wouldn't have run the network version check which is the problematic one you can disable using -n).

[didier-durand]

@jodh-intel : Thanks for this complementary info!
Can I remove "-n" in my scripts as soon as kata-containers/kata-containers#1105 gets merged?

[jodh-intel]

@didier-durand - Well that PR is for Kata 2.x (which you may want to switch to anyway? See https://github.com/kata-containers/kata-containers/releases/tag/2.0.0 for some details of 2.x). Once kata-containers/kata-containers#1105 is merged, I will fix the problem in this repository (which is for Kata 1.x only).

By the way, as an alternative to -n, you can set KATA_CHECK_NO_NETWORK=1 instead, which may be less invasive.

[didier-durand]

@jodh-intel :
I'd be happy to switch to Kata 2.x as I am doing initial tests: I'd prefer to be on last version

As said above, I currently install Kata via '$(curl -fsSL https://raw.githubusercontent.com/kata-containers/tests/master/cmd/kata-manager/kata-manager.sh) install-docker-system' as per project documentation

How do I enforce 2.x in the command line above? Any additional param that I should specify?
Thanks for your help!

BTW, I will publish my repo encompassing a fully automated GitHub workflow driving tests on MicroK8s + GCE as soon as I get it to work. It may help others. I'll let you know by then.

@didier-durand - We are developing Kata 2.0 and onwards in a different repository. As such, to install Kata 2.0 you need to look at https://github.com/kata-containers/kata-containers/tree/2.0-dev/docs/install instead. The recently updated readme in the 2.x repository explains some of the differences between 1.x and 2.x in terms of repositories: https://github.com/kata-containers/kata-containers/blob/2.0-dev/README.md.

1.x PR raised: #3070.

[didier-durand]

Thanks for the backport!

I am trying to switch to v2.0 as suggested above.

It installs fine via snap.

But, I used to run 'kata-runtime kata-check' & 'kata-runtime kata-env'. Now, I get a 'command not found' on kata-runtime. What are he replacing commands? Thanks in advance.
Didier

[didier-durand]

Please, forget my question above: I used 'find' to locate kata-runtime in the installed snap
