Errors update after installing ubuntu 18.04 bionic beaver

Question

I have already upgrade my ubuntu artful to bionic beta. But i got this errors after using command sudo apt update && sudo apt upgrade here's the error message:

After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] y
Setting up i2p (0.9.34-1ubuntu3) ...
/var/lib/dpkg/info/i2p.config: 14: /etc/default/i2p: RUN_AS_ROOT: not found
dpkg: error processing package i2p (--configure):
 installed i2p package post-installation script subprocess returned error exit status 127
Errors were encountered while processing:
 i2p
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've been trying sudo apt install -f and sudo dpkg --configure -a it always come the same error.

Solution

try

sudo dpkg --configure --pending

This will show the problem packages, then you can just remove all the problem packages using

sudo apt remove sudo apt-get remove <package_name>

and then run

sudo apt-get update
sudo apt-get upgrade
