Unable to update the system as 'yum update' fails with https://cdn.redhat.com/content/dist/rhel/server/7/%24releasever/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found.
Environment
- Red Hat Enterprise Linux 7
Issue
-
When trying to perform a yum update or yum repolist the following error occurs:
https://cdn.redhat.com/content/eus/rhel/server/7/%24releasever/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found -
I am not able to fix the yum issue. Whenever I execute any yum command I get the below :-
https://cdn.redhat.com/content/dist/rhel/server/7/%24releasever/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found Anderer Spiegelserver wird versucht. To address this issue please refer to the below knowledge base article https://access.redhat.com/articles/1320623 If above article doesn't help to resolve this issue please open a ticket with Red Hat Support. One of the configured repositories failed (Red Hat Enterprise Linux 7 Server (RPMs)), 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. Disable the repository, 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 rhel-7-server-rpms 4. 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=rhel-7-server-rpms.skip_if_unavailable=true failure: repodata/repomd.xml from rhel-7-server-rpms: [Errno 256] No more mirrors to try. https://cdn.redhat.com/content/dist/rhel/server/7/$releasever/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Resolution
-
Execute following commands:
Note: If the directory /etc/yum/vars does not exist create it (mkdir /etc/yum/vars)**
# touch /etc/yum/vars/releasever # echo "7Server" >> /etc/yum/vars/releasever -
If
redhat-releaseis missing, install it by downloading from the portal.
Root Cause
-
$releasevervariable is not getting translated correctly due to the absence ofredhat-releasepackage.$releasever You can use this variable to reference the release version of Red Hat Enterprise Linux. Yum obtains the value of $releasever from the distroverpkg=value line in the /etc/yum.conf configuration file. If there is no such line in /etc/yum.conf, then yum infers the correct value by deriving the version number from the redhat-release-server package. The value of $releasever typically consists of the major release number and the variant of Red Hat Enterprise Linux, for example 6Client, or 6Server. -
Verify
/etc/yum.conffordistroverpkgdistroverpkg The package used by yum to determine the "version" of the distribution, this sets $releasever for use in config. files. This can be any installed package. Default is `system-release(releasever)', `redhat- release'. Yum will now look at the version provided by the provide, and if that is non-empty then will use the full V(-R), otherwise it uses the version of the package. You can see what provides this manually by using: "yum whatprovides 'system-release(releasever)' redhat-release" and you can see what $releasever is most easily by using: "yum version".
Diagnostic Steps
-
The following command will show the variables used by yum:
# python -c 'import yum, pprint; yb = yum.YumBase(); pprint.pprint(yb.conf.yumvar, width=1)' -
Output of a server not translating the $releasever:

Following command can be used to verify the variables in the dump file you will see the problem clearly in the logs.
