Pirut is broken

Help. For some reason which I do not know I am no longer able to add remove software. After I have entered the root password I get the following:

An unhandled exception has occurred. This is most likely a bug. Please save the crash dump and file a detailed bug report against pirut at https://bugzilla.redhat.com/bugzilla

If possible I would like to fix this without doing a full system restore.

Thanks in advance Stewart

 

I've found a refernce to this error here: that discussion of the issue seems to indicate that doing

Code:

cd /var/lib/rpm/__db.00x
sudo rm __db.*
sudo rpm --rebuilddb 

may well sort it out.

 

Hi Daldred, thanks for you response. I copy and pasted that info in to the treminal and got the following

[user@localhost ~]$ cd /var/lib/rpm/__db.00x
bash: cd: /var/lib/rpm/__db.00x: No such file or directory
[user@localhost ~]$ sudo rm __db.*
rm: cannot remove `__db.*': No such file or directory
[user@localhost ~]$ sudo rpm --rebuilddb
rpmdb: Locker is not valid
rpmdb: Unknown locker ID: 565e
error: db4 error(22) from db->close: Invalid argument
error: cannot open Packages index using db3 - Invalid argument (22)
[user@localhost ~]$

Does this mean any thing to you?

Stewart

 

It means I got it wrong! Try again:

Code:

cd /var/lib/rpm
sudo rm __db.*
sudo rpm --rebuilddb 

(I'd put the filename in the first line where it only wants the directory).

 

Daldred thank you very much, That did the trick.

Thanks very much Stewart

 

Oh dear spoke to soon. Just tried downloading Amorak and this cropped up

Local variables in innermost frame:
url: http://www.mirrorservice.org/sites/down ... 8.i386.rpm
self: <urlgrabber.grabber.URLGrabber instance at 0x99761ec>
filename: //var/cache/yum/fedora/packages/fftw-3.1.2-5.fc8.i386.rpm
opts: <urlgrabber.grabber.URLGrabberOptions instance at 0x864e50c>
fo: <urlgrabber.grabber.URLGrabberFileObject instance at 0xce2c66c>

 

I'm guessing here, to be honest, but without digging into the Python code the clue there is that one filename it mentions. On this system, after a pirut run, there should be nothing left in the cache directory, so if there are files left in there it may be causing a problem, though I'm not sure why it should, really.

Let's try clearing the cache directory it's complaining about: we may also need to clear others later, but if dealing with that one clears up this specific error then it's a start!

Code:

 cd /var/cache/yum/fedora/packages
pwd
(see note below at this point)
sudo rm -Rf *

One caution: after the 'pwd' make sure the response is "/var/cache/yum/fedora/packages" before doing the next line. That last line removes all files and directories starting wherever you are, and since you're using sudo it will get everything - start in the wrong place and you could wipe your entire machine!

 

Hi Daldred, once again thanks a lot. I did what you said and I now have Amorak up and running.

Many thanks Stewart
