Weird 'tech_domains' warning/error in all cPanel user interfaces

Whenever my customers are using cPanel's file manager, using their email or anything else, this warning pops up at the top of every related service:

'tech_domains' array in /etc/cpanel/ea4/ea4-metainfo.json contained only invalid or empty entries. at /usr/local/cpanel/Cpanel/IP/AutoDomain/TemporaryDomain/Check.pm line 66.

I've never thought I had to report issues to you guys, as I've been using cpanel for a decade already and I've never had issues before, but this year it's the second time I'm facing weird bugs recently (the first being the 421 error I had to report 20 days ago which put down all my customer websites). What's going on?

Hey there! You should be able to remove a package to resolve the error. We have more details on this posted here:

but let me know if you have any questions!

Thank you guys, following that article fixed the issue. Any ideas about why this happened?

August 11, 2025 09:22

It looks like the package was outdated as part of work we're doing for this new feature:

https://features.cpanel.net/c/220-temporary-domains-in-whm

https://features.cpanel.net/c/232-temporary-domains-for-cpanel-users

but not everyone is experiencing the issue so we didn't release a more widespread fix.

Thanks for your explanation and fast response.

August 11, 2025 09:24

Sure thing!

Jishnu, Do you have the fix commands for a Debian/Ubuntu Installation? I see that most of the fixes usually introduced isn posted only for RH derivatives. Is there any command list to fix this on ubuntu?

You would just need to look up the package and remove it with apt instead.

August 11, 2025 15:26

Thanks cPRex, I will do that but using apt remove the server just offered to remove a bunch of other packages that were installed with cpanel-tools, is it safe to remove all of these and have them re-installed automatically with cpanel-tools again?

apt remove --allow ea-cpanel-tools

Ragheb Rustom - you wouldn't want to remove all of those dependencies, no. Your best option is likely dpkg with this:

dpkg --remove --force-depends "ea-cpanel-tools"
