Yes. I also checked that the ownership and rights of my other shells and xonsh match. The only difference is that xonsh is in /usr/local/bin.

It's a bug in xonsh. In the build_ins.py module, xonsh attempts to determine if a file is "binary" or not by opening it and reading a few bytes:
def _is_binary(fname, limit=80):
with open(fname, 'rb') as f:
for i in range(limit):
char = f.read(1)
if char == b'':
return True
if char == b'n':
return False
if char == b'':
return False
return False
Security sensitive programs like sudo are often executable but not readable, so this blows up.

My guess is that not many people are usingxonsh. It's not something I had ever heard of until I saw your question.

To be clear, sudo does work even with this bug on many systems (which is why it was missed). Some distributions choose to make sudo unreadable-but-executable. This is not categorically true for all Linux distros. There is a PR into xonsh that fixes this.

The bug has now been fixed in master. Sorry about the problem in the first place.
