genup

When I run genup

* Checking Portage configuration, please wait...
Usage: /usr/bin/emerge [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
          [-O <options>] [-P <option=value>] [-s] [-v] [-x] [-o <outfile>] [<infile>]

       /usr/bin/emerge -h | -V

Highlight the input file and write the result to <outfile>.

If no input file is given, use stdin, if -o is not given, use stdout.

If -s is passed, lexing will be done in "streaming" mode, reading and
highlighting one line at a time.  This will only work properly with
lexers that have no constructs spanning multiple lines!

I don't know that what happend. By the way, This is my first time using gentoo.And It's awesome.

Hi @snxq1995, sorry to hear you're having trouble with this ><

I have just run genup on a fresh version of the image to check, took quite a while to do the full update, but it ran to completion, and on reboot, genup still works.

On your system, it looks like emerge --info is failing. Are you running genup as root? Have you installed any other packages on your system?

What do you get if you run (as root):

pi64 ~ # emerge --info

[snxq]

use root to get the same result.

You're right.this output is the result of the emerge --info.But there is no first and last line.

Is the configuration problem?

@sakaki- Sorry,I'm a gentoo noob. Hope you don't mind.

[sakaki-]

No problem ^-^

So just to verify, if you run emerge --info as root, you get something like:

Usage: /usr/bin/emerge [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
          [-O <options>] [-P <option=value>] [-s] [-v] [-x] [-o <outfile>] [<infile>]

       /usr/bin/emerge -S <style> -f <formatter> [-a <arg>] [-O <options>] [-P <option=value>]
       /usr/bin/emerge -L [<which> ...]
       /usr/bin/emerge -N <filename>
       /usr/bin/emerge -H <type> <name>
       /usr/bin/emerge -h | -V

Highlight the input file and write the result to <outfile>.

If no input file is given, use stdin, if -o is not given, use stdout.

If -s is passed, lexing will be done in "streaming" mode, reading and
highlighting one line at a time.  This will only work properly with
lexers that have no constructs spanning multiple lines!

Is that right? If so, this would suggest you have overwritten the program emerge with something else - perhaps the program pygmentize (this has a very similar manpage to your output, see here).

Try running head /usr/lib/python-exec/python3.5/emerge - what does that display?

Also, please post the output from emerge --version, eix --installed portage and eix genup (all as root).

[snxq]

@sakaki- I saw your reply.Is there a relationship between emerge and python3.5?

Before this error occurs.I did this.

emerge --ask dev-lang/python:3.6
eselect python set 2(python3.6)

Haha! This is the reason?

[sakaki-]

Not sure that'd be enough to cause it by itself, but you could try (as root) eselect python set python3.5 and see if that resolves things (you should still have 3.5 installed, as it is in a different slot to 3.6).

If that doesn't work, then please post the output I requested above (head /usr/lib/python-exec/python3.5/emerge etc.)

[snxq]

emmm I switched to Python3.5. But It does not work. Here is the output of running head /usr/lib/python-exec/python3.5/emerge

pi64 /home/demouser/Projects # head /usr/lib/python-exec/python3.5/emerge 
#!/usr/bin/python3.5 -b

from __future__ import print_function

import platform
import signal
import sys

[sakaki-]

OK so please run (as root) which emerge and ls -l $(which emerge).

[snxq]

pi64 ~ # which emerge 
/usr/bin/emerge
pi64 ~ # ls -l $(which emerge)
lrwxrwxrwx 1 root root 31 Apr  1 15:39 /usr/bin/emerge -> ../lib/python-exec/python-exec2

[sakaki-]

That's really very strange! Is there anything else you did (run history as root) or installed that may have changed your system? Its not something I have ever had reports of from other users.

Running emerge should trigger python-exec2 which should in turn invoke /usr/lib/python-exec/python3.5/emerge (which itself looks correct, based upon the head you posted), but instead it appears to be invoking /usr/lib/python-exec/python3.5/pygmentize (based upon the output you posted).

If there are no other obvious changes you made to your system, I would recommend posting in the "Gentoo on ARM" forum (here), to see if anyone there can assist.

[snxq]

OK.

I reinstall the image, but the problem is not reproduced.

Thank you.

[sakaki-]

Glad to hear you got it working.
