uv installing for incorrect architecture (raspberry pi) #13288
Description
Summary
Running uv with any python version that is not 3.9 (system default) will result in a "Cannot open shared object file: No such file or directory" error.
Here are some logs that demonstrate the issue:

The libraries are clearly present:

One thing I'm noticing, is that this is an aarch64 machine, however uv is downloading the armv7 executables.
Running python 3.13 will download the armv7 version, yielding the same error:
yucjo@raspberrypi ~/workspace/projects/ main
