Lab 4.5 Install CRI-IO: installation issues

Hi All, I am having issues with the following steps:

I am using Ubuntu 20.04. I have tried with other CRI-IO versions but same issue. Also I have reviewed other threads related to lab 4.5, but they seem to refer to different issues.

Hi @mehlers,

I have seen similar errors when the apt source files were not properly generated.

I would revisit the previous two echo commands and then validate that the source files are set with the desired values.

Hi Chris,

I have reviewed and recreated the apt source files, but I am still getting the same error:

Hi @mehlers,

This may prove that "latest" is not always "greatest"

Although the installation steps have not changed for the latest cri-o release, this may just prove that "latest" is not always "greatest"

I would recommend following the versions presented in the lab guide, as they have been tested and worked successfully at the time the lab material was compiled. Your OS seems to be aligned with the suggested OS of the lab environment, so I would expect cri-o 1.21 installation to produce the desired results as seen in the lab guide.

Regards,
-Chris

Hi Chris,

I have tried with CRI-O version 1.21 again and it worked now! Actually I had tried with 1.21 initially as in the lab guide, and then tried with other versions as it failed, but I cannot reproduce that.

Thanks for your guidance.

Regards
Martin

Magic fingers I suppose

Yes, I was trying with 1.23.4 and getting same error.
Based on this advise I changed to 1.23 and it is successful and cri-o v1.23.1 is installed.
