我尝试通过此链接 [1] 安装 podman：https ://github.com/HealisticEngineer/Ubuntu/blob/master/podman/readme.md
命令后wget -nv https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_${VERSION_ID}/Release.key -O- | apt-key add -
我得到这个错误
https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_6/Release.key:
2021-12-14 12:42:57 ERROR 404: Not Found.
gpg: no valid OpenPGP data found.
而且我无法安装 podman...有什么想法吗？
