Issue2400

I'm installing Jython 2.7 to a fresh Linux machine with Oracle Java 8. Installation went fine otherwise, but installing pip failed. I got the following traceback on the console where I started the installer:

Traceback (most recent call last):

After searching for more information, I found closed issue #2333 which was fixed by setting JAVA_HOME as described in #2346. I was surprised because #2346 is about badly set environment variables and I didn't have any JAVA* related environment variables set at all. I tried setting JAVA_HOME but that didn't help.

I also found open issue #2350 with a workaround to run `jython -m ensurepip` after installation. That didn't work for me either. I got the same traceback as I got when installing Jython itself.

Another workaround in #2350 was using the silent installation. I tested that with

    java -jar ~/Downloads/jython-installer-2.7.0.jar -s -d ~/jython

but got same traceback again.

Little more information about my system:

1. Linux Mint 17.2. Fresh install.

2. Java 1.8

$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

3. All other Java versions ought to be removed.

$ update-java-alternatives --list
java-8-oracle 1 /usr/lib/jvm/java-8-oracle

4. No Java related environment variables set.

$ env | grep -i JAVA | wc -l
0

Hey Pekka,

Can't seem to reproduce your issue, but I'm on Mac.

Can you run this code and paste output here?

from os import _posix_impl
pwuid = _posix_impl.getpwuid(1)
print pwuid
dir(pwuid)
pwuid.password

Thanks!

Thanks for looking at this Darjus. I tested that `os._posix_impl.getpwuid(1)` returns `None`. Anything else I should look at?

Made me think that http://bugs.jython.org/issue2405 may be related.

#2405 looks interesting. Mint 17.2 that I use is based on Ubuntu 14.04 and I'm using Java 8. Should I try with Java 7 and see does that work?

I'm pretty sure this is now fixed, as of https://hg.python.org/jython/rev/b256a80cbbc5 - but definitely we will reopen if I'm wrong. Please try out from trunk, or from next week's RC.

Cool, I'll definitely test RC once its out.
