I'm running into the following package error on CentOS 7 installation while customizing an ISO for automated installs. 

packaging.log:03:52:50,495 ERR packaging:  Error populating transaction after 10 anaconda retries: failure: perl-HTTP-Tiny-0.033-3.el7.noarch.rpm from anaconda: [Errno 256] No more mirrors to try.

I've verified the above package is in the Packages/ directory. Verified that the package appears in the comps.xml and .xml files within the repodata/ folder .gz files.

Createrepo command is:

[root@server01 Packages]# createrepo -dpo .. . -g /server-images/working/repodata/521f322f05f9802f2438d8bb7d97558c64ff3ff74c03322d77787ade9152d8bb-c7-x86_64-comps.xml

What could be the issue or what could I check next? I'm not able to find much on the web.

Thx,

I've tried the solution on this page but adding -untranslated-filename had no effect:

https://unix.stackexchange.com/questions/232155/centos-7-install-error-populating-transaction

Anaconda keeps trying to look for packages under file:///run/install/repo rather then file:///run/install/repo/Packages/ where packages reside.

Leaning towards my createrepo command rather than anything else as the culprit but just can't pinpoint the specific syntax I might be needing.

When you generate your repo, prior to generating the ISO, make sure you are in your working root and do NOT specify ./Packages as an argument to createrepo:

createrepo -dpo . ./ -g ...etc...

and NOT

createrepo -dpo . ./Packages -g ...etc...
