The ultimate guide on how to run PKHeX on Linux [updated 5/2026]

[autofire372]

I set up a fresh wine prefix for PKHeX only on a new laptop, installed dotnet 10.0.6 into it, and I can't open the Trainer Info tab editing a Gen 5 save. All I get are CultureNotFound exceptions. I tried forcing en-US.UTF-8 using environment variables, but it still won't work.

I am aware of this. Starting from Wine version 11.5, there is currently a regression due to a new language code added to ICU, which for some reason is not recognized. There is already an open bug tracking this issue, hopefully someone will see and fix it. For now, use version 11.4, which is the latest safe version.

No can do; I'm on an Arch-based distro, so downgrading wine isn't really feasible.

I guess I'm stuck waiting for a bugfix...

You can easily downgrade packages with downgrade. That's exactly what I'm doing right now.

Figured it out; had to re-create PKHeX's wine prefix afterward, but it's working now.

Hey made an account because I'm running into an issue. So I got to step four and followed all directions, including adding the bit of code you mentioned to add before. I received this string of code:

I've tried using stable Wine, I've tried using staging and received this exact error. PKHeX won't start and I'm confused, because when I followed this guide it started before and was working fine. When I got to when I wanted to use it it just crashed on startup. Any clue on how to fix this?

 

EDIT: As a note I'm on Linux Mint 22.3

Needed to state which version of Linux I'm on.

As mentioned above, try on a previous version of wine (such as 11.4).
