It seems the libudev.so.0 file is missing.

Could you please check if you have the following file instead: /usr/lib/x86_64-linux-gnu/libudev.so.1?

If so, you can create a symbolic link between that file and the missing file:

ln -s /usr/lib/x86_64-linux-gnu/libudev.so.1 /usr/lib/x86_64-linux-gnu/libudev.so.0

Then the error should be gone. If it still doesn't find the file, try adding /usr/lib/x86_64-linux-gnu/ to the LD_LIBRARY_PATH.

Note: the library path /usr/lib/x86_64-linux-gnu/ might differ based on your system.

@nathanlct That works! Thanks a lot! For more details, I installed libudev by running

sudo apt-get install -y libudev-dev

and libudev.so.1 is installed at /lib/x86_64-linux-gnu/, then link

ln -s /lib/x86_64-linux-gnu/libudev.so.1 /usr/lib/x86_64-linux-gnu/libudev.so.0

Thanks for bringing this issue up! We're going to work on seeing if there's a way to prevent this from happening again but in the meantime I'll close this issue if it's resolved. Feel free to re-open it if further issues arise.
