Expired or Invalid Certs OR missing resource

[bearrito]

Seems related to https://github.com/containers/podman.io/issues/296

But that was related to the signing key and this seems related to certs. This is on: Ubuntu 20.04

Here is the output from my apt-key list

If you visit in a browser you''ll get

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for 195.135.221.134. The certificate is only valid for the following names: *.opensuse.org, opensuse.org
 
Error code: SSL_ERROR_BAD_CERT_DOMAIN

HOWEVER

I also see the following when visiting https://download.opensuse.org/repositories/devel:/kubic:/libcontainers/stable/xUbuntu_20.04

Resource is no longer available!

The requested URL is no longer available on this server and there is no forwarding address. If you followed a link from a foreign page, please contact the author of this page.

If you think this is a server error, please contact the [webmaster](mailto:[email protected]).

Maybe a caching server issue ??

Kubic no longer supports builds for Ubuntu 20.04, or anything older. The old files are no longer available either.

I've created an MR to remove the references to that repository.

https://github.com/containers/podman.io/pull/590

There are comments at https://build.opensuse.org/package/show/devel:kubic:libcontainers:unstable/podman indicating that this is intentional, in addition to the obvious missing repository.

There is also discussions on other online forums suggesting that podman requires a newer version of go than supported by Ubuntu 20.04, and the effort required to remedy that is more than anyone is willing to provide.

The current best options seems to be the dannf/podman ppa.

sudo add-apt-repository ppa:dannf/podman
sudo apt update

However I don't think it should be in the official docs, it doesn't look well supported.
