mib browser Zenapck install fails - and can't uninstall

Zenoss 2.5.2 on OpenSuSE 10.3.  Mib Browser ZenPack 1.08.  Brand new install so no history lying around.  Zenoss server is zen-01.skills-1st.co.uk.   Tried to install zenpack with:

 

zenoss@zen-01:/code/zenpacks> zenpack -v 10 --install ZenPacks.community.mib_utils-1.08-py2.4.egg
2010-06-21 21:49:25,265 INFO zen.ZPLoader: Loading /srv/zen-01-data/local/zenoss/zenoss/ZenPacks/ZenPacks.community.mib_utils-1.08-py2.4.egg/ZenPacks/community/mib_utils/objects/objects.xml

ERROR: zenpack command failed. Reason: KeyError: 'zen'

 

Bounced zenhub, zopectl and zentrap.  Don''t see broser icons from MIBs menu.

 

Command line thinks the zenpack is installed, as does Settings -> ZenPacks:

zenoss@zen-01:/code/zenpacks> zenpack --list
ZenPacks.community.mib_utils (/srv/zen-01-data/local/zenoss/zenoss/ZenPacks/ZenPacks.community.mib_utils-1.08-py2.4.egg)

 

 

But cannot de-install this broken zenpack:

zenoss@zen-01:/code/zenpacks> zenpack --remove ZenPacks.community.mib_utils
ERROR: zenpack command failed. Reason: NotImplementedError:

 

Tried all sorts but can't get rid.  Can't reinstall because it tries to remove it first...

 

Looking at the ERROR from the install, I am wondering if the problem is with the Zenoss server name of zen-01 - can't see where else it might have a KeyError of zen ?????

 

Anyone have any thoughts or fixes?

 

Cheers,

Jane

    Update....

    It's not just the MIB Browser ZenPack - get the same with ZenPacks.zenoss.HttpMonitor and I suspect with others.  Exactly the same error message about KeyError: 'zen'.  Makes me think something may have truncated my zen-01 hostname at the hyphen....

    Cheers,

    Jane

     

    PS. I have these same ZenPacks installed on other 2.5.2 implementations with no problem - but the Zenoss server doesn't have a hyphen in the hostname.

    Re: mib browser Zenapck install fails - and can't uninstall

    OK.  This isn't hostname and it isn't specific to the MIB Browser ZenPack.  If your $ZENHOME has a hyphen in it (I had /srv/zen-01-data/local/zenoss) then you get the:

     

    ERROR: zenpack command failed. Reason: KeyError: 'zen'

     

    message on install where the KeyError: 'zen' seems to be the bit before the hyphen.  Once you have done this, you cannot deinstall the zenpack (NotImplementedError) - I've tried with command line, GUI and using the Zope Interface directly - you still can't get rid of it and you can't reinstall because that does an uninstall.

     

    Most ZenPacks that I tried on the system with $ZENHOME having a hyphen, barfed.  If you reinstall Zenoss, ensuring ZENHOME has no hyphen (and no dot - that is already a know problem with ticket 5838) then all the ZenPacks (that I've tried) install sweetly and can be removed.  I have opened ticket 6915 - http://dev.zenoss.com/trac/ticket/6915 .

    Hi Jane,

     

    I also can't unistall the ZenPacks.community.mib_utils version 1.08 on my Zenoss 3.2.1. I get a simular output "NotImplementedError".

    I have the same issue with the same zenpack.  Kingpin, were you able to resolve this?

    Re: mib browser Zenapck install fails - and can't uninstall

    The answer is to hack the __init__.py file of the ZenPack - it is documented here - docs/DOC-3412

     

    I will quote the relevant bit here:

     

     

    With many thanks to Kells for the hint....

    If you have this ZenPack installed on 3.x system that has been upgraded from 2.5 system, the functionality doesn't work and you get the message shown above.  Drill down to $ZENHOME/ZenPacks/ZenPacks.community.mib_utils-1.08.egg/ZenPacks/community/mib_utils and edit the __init__.py to change leaveObjects=False to leaveObjects=True, bounce zenhub and zopectl and try again to remove the ZenPack - it worked for me!

     

    Cheers,

    Jane
