Description

So I see the issue is with permissions

PermissionError: [Errno 13] Permission denied: '/proc/stat'

I can try working on a termux friendly approach here in a couple days.

Traceback (most recent call last): File "/data/data/com.termux/files/usr/lib/python3.9/site-packages/psutil/_common.py", line 405, in wrapper return cache[key] KeyError: (('/proc',), frozenset()) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/data/data/com.termux/files/usr/lib/python3.9/site-packages/psutil/_pslinux.py", line 309, in set_scputimes_ntuple("/proc") File "/data/data/com.termux/files/usr/lib/python3.9/site-packages/psutil/_common.py", line 407, in wrapper ret = cache[key] = fun(*args, **kwargs) File "/data/data/com.termux/files/usr/lib/python3.9/site-packages/psutil/_pslinux.py", line 276, in set_scputimes_ntuple with open_binary('%s/stat' % procfs_path) as f: File "/data/data/com.termux/files/usr/lib/python3.9/site-packages/psutil/_common.py", line 713, in open_binary return open(fname, "rb", **kwargs) PermissionError: [Errno 13] Permission denied: '/proc/stat' Bpytop exited with errorcode (1).

Research direction
The issue is a PermissionError when accessing /proc/stat on Termux/Android. To fix, modify the code in bpytop to handle PermissionError gracefully, perhaps by using try/except around the file access and providing a fallback or user friendly error message. Examine the psutil library usage and consider adding a check for file accessibility before opening. Test the changes in a Termux environment. Look at existing exception handling in the codebase for similar patterns.
