Issue description

Hello I am using pixi 0.41.4 and I started to get this error when I simply try to add anything. This was not happening before. When I simply try to add python this is happening.

Any ideas?

Expected behavior

pixi add python
    ✔ validate cache       22 packages in 1s 371ms
    ⠈ download & extract   [00:00:02] [━━━━━───────────────] 11.82 MiB @ 2.30 MiB/s ncurses (+2)

It looks like your cache got corrupted. You could clean the cache by running pixi clean cache --conda to remove these files. To avoid the removal of the full cache you could also go into the /home/ilm254/.cache/rattler/cache/pkgs dir and only remove the folders that are represented in the error like tk in this example.
