E: Sub-process /usr/bin/dpkg returned an error code (1)

The culprit seems to be the avg2013flx which apparently is in a strange state - installed and not yet configured, but the files are not there.

Try

sudo dpkg --purge avg2013flx

and copy/paste all output.

This is the output when i try dpkg --purge avg2013flx

Thanks

Here is the output of file /etc/init.d/avgd

Please try the last remark by John0278 (jjg6908) here:

https://answers.launchpad.net/ubuntu/+question/4392

So run this Terminal command instead:

sudo dpkg --remove --force-all avg2013flx

sudo dpkg --remove --force-all avg2013flx didn't work
