Upgrade to 13.04 Crashes on Blueman, or Bug #1016942

Setting up blueman (1.23-1) ...

So I was upgrading my machine a few days ago after neglecting dist-upgrades for a while and realized that there was a new release out, 13.04 to be exact. I was running on Lubuntu 12.04 and enjoying it, but I was willing to take the plunge. My first mistake was I had left my system set for long term releases, so when I ran

$ sudo do-release-upgrade

my response was simply

Checking for a new ubuntu release  

No new release found  

after checking my /etc/update-manager/release-upgrades and finding that it had Prompt=lts all I had to do was change Prompt=lts to Prompt=normal and all was well.

For awhile.

During my update, I may or may not have pressed "ctrl-c" to break out of what I thought was a text editor, but was really something else that sent my break command to my release upgrade in progress. I had to reboot to come back to life. When I did, I was thankfully greeted with a login prompt, but no networking. I followed the commands from the previous post to get back on my feet, and then ran into this new issue. Upgrade crashes on blueman. So I run

$ sudo apt-get remove blueman

and

$ sudo dpkg --configure -a

$ sudo apt-get install -f

until I have everything installed and configured besides blueman and lubuntu-desktop . From here I was racking my head for days, until I came upon a nice little IRC log here. I had been going through the bug logs here and found the same error earlier, but nothing new. The IRC log recommended quite a few options, but the only one that did anything for me (and the only one I even tried for that matter) was

$ sudo service dbus restart

and then it worked like a charm! Whoever it was in that IRC chat, thanks!

Enabling Networking from Terminal in Lubuntu 12.04

I was running a "sudo do-release-upgrade" on my Lubuntu 12.01 laptop when durring a series of unfortunate events, I broke it. It rebooted and I was able to login, but no X session. Here is what I did to come back. I typed:

1. sudo ifconfig eth0 up (in order to logically enable the interface)
2. sudo ifconfig eth0 192.168.0.4 (to set the ip since dhcp wasn't working)
3. sudo ifup eth0 (this should have turned dhcp on for eth0)
4. vi dns.txt
5. enter "nameserver 4.2.2.2" and save and quit
6. cat dns.txt | sudo resolvconf -a eth0
7. And you should be live!
