Installation solving environment and e2display.py problems

[Madison Ell]

Hi,

I'm trying to install the latest version of eman2 through Linux anaconda (Ubuntu), but the "solving environment" attempts fail and I cannot run the e2display.py script.

These are the error messages I receive:

Collecting package metadata (current_repodata.json): ...working... done Solving environment: ...working... failed with initial frozen solve. Retrying with flexible solve. Solving environment: ...working... failed with repodata from current_repodata.json, will retry with next repodata source.

qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.  

I'm using the latest version of python in a WSL 2 environment, and I have tried uninstalling and reinstalling several times. How can I fix this?

Thank you in advance!

Madison

Ok, I'm not 100% sure _exactly_ what you mean by "Linux anaconda (Ubuntu)".

- it seems clear that you are using Ubuntu Linux under WSL2, but what version? (may have a large impact)

- not clear what the source of your Anaconda is

- which instructions are you following ?  There are 3 methods you can use to install:

https://eman2.org/Install/BinaryInstallAnaconda/2.99

- not clear at what step you got the solving environment error? Was that the last message?

The last message you showed isn't an EMAN2 issue, but an Ubuntu level issue.

Bottom line is that we need more complete information to help...
