Can't install after modify comps.xml file

[Jack Ngo]

Hi everyone,

After I modifed RHEL7 comps.xml in /repodata dir and use createrepo command
to re-create a new /repodata dir, I can't install any Base Environment.

I got error message: "error populating transaction after 10 retries:
failure: Packages/tar-1.26-29.el7.x86_64.rpm from anaconda: [Errno 256] No
more mirrors to try."

If I use original /repodata dir, it's ok. I use NFS installation method.

Please help me !!! Thank you so much !!!

First, thanks Spike so much for helping me.

Oh yes, actually I know it's a very bad idea, but I want to check how to
modify and update comps.xml file.

I did nothing, I only copy RH original comps.xml file, rename it and
re-create a new repodata/ dir, then replace a new repodata/ dir into RH
original repodata/ dir. I can boot it and see Base Environment but can't
install, I think there is something related to RH original comps.xml file,
so I can't replace it.

BTW, thank you so much again and I still have a question. If I want to add
a new environment (ex: Everything - Full packages), how to define it in
comps.xml file? Hmm, only one way is list all group in
<grouplist></grouplist> or can I use another way (ex: use <grouplist/>,...)
? Because I can't install, I can check by myself.

Hmm, I know this is a crazy idea but I want to know more about comps.xml
file and Anaconda.

Final, thanks for help and solve my crazy ideas.
