Hi,

as dev-db/pgadmin4 got removed from Portage due to yarn issues as mentioned in https://bugs.gentoo.org/794460#c20
I tried following https://ogris.de/howtos/gentoo-pgadmin4.html to install via venv/pip. But it's failing due to kernel version? What can I do?
Code:
$ python3 -m venv ~/opt/pgadmin4
$ . ~/opt/pgadmin4/bin/activate
$ pip install pgadmin4

Sorry, I don't know how to fix your issue or tell whether it is kernel related or not.
I seems like the post you're using as a guide is rather old :roll:

I can only share my experience with dev-db/pgadmin4 ebuilds.
I've successfully maintained out of the tree dev-db/pgadmin4 locally up to 6.21.
It worked installing the desktop version as expected.

dev-db/pgadmin4 has a large python packages stack, many of those possibly too old, i.e. conflicting, for the portage tree
I also had to create/upgrade some of those locally

Starting from version 7, desktop version failed.
To my little knowledge makefile has changed, and I could not find the option for desktop version in it.

I couldn't find valuable online information for desktop mode manual install.
IIRC debian and arch seems to have desktop binary packages, though.

I came to the docker solution which works here, in server mode.

I you need a quick working solution, that could be a workaround.

I find it rather unfortunate gentoo doesn't support official postgresql frontend whatever mode.
Maybe one day a volonteer will...

Thks 4 ur attention, interest & support.

As I read the output, the bundled version.py rejects your uname as ill-formed. This seems like a bug to me, because (1) unames are free form, and expecting it not to contain -gentoo is wrong, and (2) since many non-Gentoo distributions are quite free with their backports, kernel version numbers are largely meaningless as to what features a kernel will or will not contain. Therefore, in my opinion, programs should not inspect or attempt to decompose the uname, and should only read it for the purpose of showing it in logs, where a person might be able to interpret it.

In the short term, you may need to patch out this check, or patch the regex it uses.
