Em vez de usar o yast, você pode editar os arquivos de texto *.repo abaixo de /etc/zypp/repos.d/ com um editor de texto.
Você pode testar via
$ zypper ref
A BTW usa curl -L ... para seguir redirecionamentos.
Eu quero mudar
http://download.opensuse.org/tumbleweed/repo/oss/
para
https://download.opensuse.org/tumbleweed/repo/oss/
no yast - > repositórios de software - > editar - > editar partes do repo - > "x" o https (antes de ser http simples), mas apenas me dá a mensagem de erro:
Download (curl) error for 'https://download.opensuse.org/update/tumbleweed/repo/repoindex.xml':
Error code: Bad URL
Error message: Protocol "http" not supported or disabled in libcurl
Mas se eu tentar com a mão, tanto http quanto https falharão:
