When running the migration tool centos2ol.sh I get following errorlist => how come he doesn't find the REPOMD.xml file? Looking for yumdownloader... Backing up and removing old repository files...

I'm not sure how that URL is being generated, but it's very wrong. The URL for ol7_latest is https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/

[Djelibeybi]

Could you please change set -e to set -ex on line 9 of the script and paste the full output? Use triple backtickts to format it as console output.

[JJDC982]

Hi Avi, Thanks for answering so fast, I changed the “-e” to “-ex” on line 9 and this is the output :

If there is anything wrong in the script can you give me the correct statement to change at mentioned linenumber ? Thanks for checking my error. Error is very strange because I executed this bash file on an experimental cluster of 8 servers and 5 gave no errors and 3 did abort. We still have 5.000 servers to convert on our supercomputer!

@JJDC982 the way I read this output, you have an enabled repo labeled yum.oracle.com somewhere in a file in /etc/yum.repos.d. I believe this is what's causing this error.

[Djelibeybi]

Yeah, can you check all the files in /etc/yum.repos.d/ and make sure none of them point to yum.oracle.com before you start? They should all be the original CentOS files.

@JJDC982 - I'm closing this issue. If you have further questions, please let us know.
