Upgrading from Debian Wheezy to Jessie

Upgrading from Wheezy to Jessie on my Linode was fairly simple. I followed the upgrade
guide on linode.com. I had a few surprises..mostly due to my dotdeb updates (which I disabled
during the upgrade). I like to do all this as root. You can add sudo to commands if you
do not like to use root.

To summarize, here are the steps:
1) stop all services.
2) comment out any extra repositories in /etc/apt/sources.list.
3) Edit /etc/apt/sources.list and change all “wheezy” to “jessie”
with vi %s/wheezy/jessie/g
4)update packages list: apt-get update
5)apt-get install apt dpkg aptitude
6)update apache2 sites-available to add .conf extension to all sites.
7)apt-get dist-upgrade
8)Watch the process so you can answer any update questions that occur.

After completion, reboot the system using the Linode manager and login to test.

Debian 8 Jessie is a nice upgrade. I was worried about systemd however, Debian made it
pretty much transparent.

I will update the problems I had and fixes in a future post.
