yumex error on start-up

[z99]

hi,
i installed yumex:yum -y install yumex,
when i start yumex it came with this error:
fatal error:backend-not-running
backend not running as expected (yumex will close)
how can i solve it?
thanks in advance

root cannot install yumex;
Generally under the user carries out yumex, inputs the root password confirmation again, may renew.

thanks chi0541
i install yumex with root,
yum is the back-end for yumex ,yum works well,and i don't know what the problem is!
i just can't start it

How do you start yumex? Do you go to Applications->System Tools->Yum Extender, or do you start it from a terminal?

[z99]

Applications->System Tools->Yum Extender,the yum gui won;t even start,
but from terminal it starts and after loading suddenly backend not running error will appear
is there any difference between the 2 ways of starting yumex?[COLOR="Silver"]

[sidebrnz]

AFAIK, the only difference is that the terminal allows you to see those error messages.

[z99]

any idea?
fatal error:backend-not-running
backend not running as expected (yumex will close)
how can i solve it?

Hi z99,
If it helps, I run yumex on the command line in Fedora 11 and it works. I ran a command that might help you:

root@bmicek ~]# ps -ef | grep yum
brian    24018 21928  0 21:21 pts/5    00:00:00 /bin/bash /usr/bin/yumex
brian    24019 24018 24 21:21 pts/5    00:00:02 /usr/bin/python /usr/share/yumex/yumex.pyc
brian    24020 24019  0 21:21 pts/7    00:00:00 /usr/bin/yumex-yum-backend 2 True False
root     24021 24020  0 21:21 pts/7    00:00:00 /usr/sbin/userhelper -w yumex-yum-backend 2 True False
root     24025 24021 80 21:21 pts/7    00:00:08 /usr/bin/python -E /usr/share/yumex/yumex-yum-backend 2 True False

I am not familiar with how yumex works, but it sounds like /usr/bin/yumex-yum-backend is your problem. Can you see if you have it? Here is some more stuff that might help:

[root@bmicek ~]#  /usr/bin/yumex-yum-backend
Loaded plugins: fastestmirror, protectbase
:started
:ready

[root@bmicek ~]# /usr/bin/yumex-yum-backend --help

Usage: yumex-yum-backend [options]

Options:
  -h, --help  show this help message and exit
[root@bmicek ~]#

thanks BrianMicek ,
running /usr/bin/yumex-yum-backend:
that's what i got:
Loaded plugins: presto
Traceback (most recent call last):
File "/usr/share/yumex/yumex-yum-backend", line 61, in <module>
my = YumServer(debuglevel, plugins, offline, repos)
File "/usr/lib/python2.6/site-packages/yumexbackend/yum_server.py", line 208, in __init__
dscb = DepSolveProgressCallBack(ayum=self)
TypeError: __init__() got an unexpected keyword argument 'ayum'

should i edit yum_server.py for TypeError: __init__() got an unexpected keyword argument 'ayum'?
thanks

[sidebrnz]

Not unless you know exactly what you're doing. Do you know what type of argument __init__() is supposed to get or why 'ayum' is wrong? If not, you're likely to do far more harm than good.

[z99]

so what if i replace the file with someone who can run yumex correctly?

Hello,

what happened with this topic, it seems to be dying...
I have exactly the same problem, this is what happens when I try to start:

# yumex-yum-backend
Traceback (most recent call last):
File "/usr/share/yumex/yumex-yum-backend", line 61, in <module>
my = YumServer(debuglevel, plugins, offline, repos)
File "/usr/lib/python2.6/site-packages/yumexbackend/yum_server.py", line 208, in __init__
dscb = DepSolveProgressCallBack(ayum=self)
TypeError: __init__() got an unexpected keyword argument 'ayum'

PLEASE help to solve that really annoying issue!!

Thank you!!
