Hi,

I keep getting a dialog box pop up saying 'Failed to initialize packaging backend'. When I click on more details I get the following,

Traceback (most recent call last):
File "/usr/share/PackageKit/helpers/yum/yumBackend.py", line 3078, in __init__
self.repos.confirm_func = self._repo_gpg_confirm

startupconf = config.readStartupConfig(fn, root)

startupconf.releasever = _getsysver(startupconf.installroot, startupconf.distroverpkg)
File "/usr/lib/python2.6/site-packages/yum/config.py", line 953, in _getsysver
raise Errors.YumBaseError("Error: " + str(e))
YumBaseError: Error: rpmdb open failed

Does anyone have any suggestions to resolve this please?

Thanks.

Looks like you have lost connectivity to the internet. What type of install did you do i.e. full DVD, Express CD, etc?

I used the full DVD install. Its been working fine for about 3 months and has only started giving me this error in the last few days. When I boot the machine I sometimes get the message above with a message to try yum-complete-transaction.

I still have access to the internet from the machine.

Maybe a YUM Database error/corruption

Found the following at Fedora

It seems like the rpm database is hosed I would do this as root from a terminal

Code: Select all
Code: rm -f /var/lib/rpm/__db* rpm -vv --rebuilddb yum clean all

try that and report back on if it worked.

A little bit late, but yes it worked! Thanks.
