Maybe the EU can develop its own version of Linux OS, just like North Korea.

When legislators start getting involved they will want to inevitably have their "own" version of something and their own SLAs and contracts.
The reason they went with Microsoft/IBM/Oracle and others back in the day for software solutions is; they know on a piece of paper what they are getting, and who they can blame if they don't get it.
With Opensource OS and software, even with auditing and stuff, there is no way to blame anyone apart from end-users. For politicians and bureacracts, that is a scary thing, as they will be the ones to blame (read: asses on the line)
The consultation is great and all but
As someone who has watched on the sidelines how Opensource governance turns projects into hydra monsters (Redhat, Jakarta EE). I wouldn't be surprised in a few years we will have a EU approved OS that is controlled by bureaucracts.
But who knows, maybe they will just become end users of a popular distro and other opensource software.
What for? Plenty of maintainers for various distros are from Europe and/or the EU.
For example: https://map.debian.net/
Is all the distributions where most core developers already live in Europe/EU not enough for you? Take a look at where most of the active contributors live for some distributions, and I think you'd be surprised :)
I don't get it - do you think the US government doesn't have homegrown linux distros?
Finland (where Linux comes from) is in the EU. There are also a few European linux distributions you may have heard of: e.g. Debian, SUSE, Ubuntu (UK), Mandrake/Mandriva/Mageia, Knoppix, etc.
