I am running Fedora 36 (had the same issue in Fedora 35) on a Lenovo
IdeaPad. After installing sage using dnf I tried running it but it failed
due to: "ImportError: cannot load Singular library from libSingular.so
(b'libSingular.so: cannot open shared object file: No such file or
directory')". The full error report is:
Error in sys.excepthook:
Traceback (most recent call last):
File "/usr/lib64/python3.10/pathlib.py", line 1303, in is_dir
return S_ISDIR(self.stat().st_mode)
AttributeError: 'str' object has no attribute 'stat'
Original exception was:

I've had issues with installing sage with conda as well. Not being able to
get the kernel to connect in Jupyter.
