I’ve tested the subscription at my test environment. @giacomo After you informed me that test is over I can’t update my system any more. Following error I get on yum update:
[root@GroupwareBackup log]# yum update Loaded plugins: changelog, fastestmirror, nethserver_events https://m1.nethserver.com/stable/7.4.1708/base/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 403 - Forbidden Trying other mirror. To address this issue please refer to the below wiki article https://wiki.centos.org/yum-errors If above article doesn't help to resolve this issue please use https://bugs.centos.org/. https://m1.nethserver.com/stable/7.4.1708/centos-sclo-rh/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 403 - Forbidden Trying other mirror. One of the configured repositories failed (Stable mirror: SCLo rh 7), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=sb-centos-sclo-rh ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable sb-centos-sclo-rh or subscription-manager repos --disable=sb-centos-sclo-rh 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=sb-centos-sclo-rh.skip_if_unavailable=true failure: repodata/repomd.xml from sb-centos-sclo-rh: [Errno 256] No more mirrors to try. https://m1.nethserver.com/stable/7.4.1708/centos-sclo-rh/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 403 - Forbidden
I found that it also could be a DNS Problem, so I tried to ping google and the name is resolved, but the data packages are not send.
