CPAN build and cache directory called "no" created under /home

[gkgcpanel]

Recently built and installed a new cPanel server. Noticed today that there is a directory called "no" under the /home partition...

/home/no

Inside it, is a Metadata file and a sources/ directory.
Inside the sources/ directory is:
authors/
MIRRORED.BY
modules/

Inside authors/ is a 01mailrc.txt file
Inside modules/ are: 01packages.details.txt and 03modlist.data

Doing some research, I found that this is part of the CPAN build and cache directory that is created while cPanel is being installed.

So, I went back to /var/log/cpanel-thread0.log and searched for /home/no

First of all, I'd like to create this directory. Where?

CPAN build and cache directory? [/root/.cpan] no
The path 'no' is not an absolute path. Please specify an absolute path
CPAN build and cache directory? [/home/no]

Looks like the system should have simply sent an ENTER for the default /root/.cpan directory, and instead sent "no" with an ENTER. The next line then stated that 'no' is not an absolute path and recommended /home/no which is where the install then sent ENTER and that appears to be how /home/no got created.

Reading further in the log file, I come across this:

If you're accessing the net via proxies, you can specify them in the
CPAN configuration or via environment variables. The variable in
the $CPAN::Config takes precedence.

Your ftp_proxy?
Your http_proxy?
Your no_proxy?
You have no /home/no/sources/MIRRORED.BY

BUMP!

Anyone know the answer here???

[cPanelDon]

Is it ok to remove this no directory from the /home partition? I assume so, but just want to make sure.

Yes; to the best of my knowledge it should be safe to remove the specified directory path of the CPAN build directory.

Given the reported details I believe the issue should be escalated via a support request; if a bug is suspected please note that the best avenue to report it is via our ticket system, such as by using the link in the top-right corner of the forums, labeled Bugs; using this method helps to ensure greater efficiency, accuracy in diagnosis, full and in-depth investigation and faster resolution. Thank you for your understanding.

[regx]

I have the same issue.
Did you rm the /home/no dir and did that cause any issues for you?

[cPanelMichael]

Hello

Did this happen recently, or has that directory existed for a while?

To reiterate what cPanelDon mentioned, it should be safe to remove the specified directory path of the CPAN build directory. That being said, blindly removing a directory is rarely recommended. I suggest browsing into the directory and ensuring it is in-fact the CPAN build directory before removing it.

Thank you.
