on ubuntu server 12.04, whenever I invoke a program it gives the following output

[dude_the_rude]

root@mserver:~# lpstat -p
Sorry, command-not-found has crashed! Please file a bug report at:
https://bugs.launchpad.net/command-not-found/+filebug
Please include the following information with the report:

command-not-found version: 0.2.44

ALSO,

apt us archives are almost always offline when I want to update the server.

or even when I want to install new software.

The program /usr/lib/command-not-found always crashes on a fresh installation of ubuntu-server 12.04.

It doesn't crash on ubuntu-desktop (upgraded from 11.10 to 12.04).

The crash seems related to the environment variable LC_TIME. The program crashes if LC_TIME is set to any locale except C:

### CRASHES ###
LC_TIME=it_IT.UTF-8 /usr/lib/command-not-found -- traceroute

### works ###
LC_TIME=C /usr/lib/command-not-found -- traceroute

### works ###
LC_TIME= /usr/lib/command-not-found -- traceroute

Thus the bug can be avoided adding the following code to /usr/lib/command-not-found:

try:
    import os
    del os.environ["LC_TIME"]
except:
    pass

Obviously this is only a workaround until the bug is fixed.

Thanks a lot for taking the time to workaround this. I wonder where to put it exactly? I recognize the file is written in python but it is a long one to try to figure out while having to complete another project.

Thanks in advance.

Interesting! Please, anyone may telll me:

Has there been changes in the locale environment with Ubuntu 12.04? Because I found several programs NOT working on 12.04 beta as long as the locale settings are set to something else than default, especially display of numbers and currencies etc. - not language wich is set to English.

Some of those programs always crash at start just like command-not-found, but they give some error messages when started from shell which lead me to the locale setting.

So, there seems to be a huge problem with the locale, and I am not sure if it's the best way to a solution to find all programs which now fail instead of fixing the locale thing?!?

[Mike (7dlqb2n4t)]

It appears the locale (or some locale files?) are missing (I started Ubuntu 12.04 LTS on Amazon EC2).

I fixed it by generating my locale:
sudo localedef -v -c -i en_US -f UTF-8 en_US.UTF-8

command-not-found could probably handle this more gracefully.

Did not help me, but I stumbled on this and it is working now:

[Nonox (nbulian)]

This worked for me too, thanks!

[Sergey Ponomarev (stokito)]

I fixed it by changing one string in /usr/lib/command-not-found
Was:
 locale.setlocale(locale.LC_ALL, '')
I made
 locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

But it also just workaround

Hey, I wrote command-not-found. No the patch from comment 8 is not valid.

The real solution is more complex. If there is anyone that wans to step up I will gladly discuss this and help them implement it. I have no time to devote to this program sadly so that's why I need someone that can help
