KeyError: 'getpwuid(): uid not found: 60002'

When I run Python code with isolate, I receive this error:

Failed to import the site module
Traceback (most recent call last):

    userhome = pwd.getpwuid(os.getuid()).pw_dir
KeyError: 'getpwuid(): uid not found: 60002'
Exited with error status 1

I did that operations:

cd `isolate --box-id 3 --init`/box
cat > a.py

#!/bin/python
print ("asdf")

chmod +x a.py
isolate --box-id 3 --run -- ./a.py

Your installation of Python requires the current user to have an entry in /etc/passwd corresponding to his UID.

Your Isolate runs under UID 60002 and there is either no passwd file inside the sandbox at all, or there is one which does not contain this UID.

I fail to find any reason why this error should be fatal, so please consider filing a bug report for your Python package.

As a work-around, you can add a proper passwd file in your sandbox.

How to add a proper passwd file in my sandbox?

[gollux]

There are two easy possibilities:

(1) Create it as etc/passwd in your box directory (that is, the one printed by isolate --init).

(2) Add an entry to your system-wide /etc/passwd and use the --dir option to bind /etc in the sandbox.
