I recently updated to firefox 17 during a system upgrade.
$ sudo apt-get update && sudo apt-get upgrade.
How do I revert back to a previous package version? I'd like to get back to firefox 16.0.2.
I'm experiencing what appears to be a name resolution issue in Ubuntu 12.04 Server edition when configuring my computer to use static ip.
In /etc/network/interfaces:
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.28
netmask 255.255.255.0
gateway 192.168.1.1
Running $ sudo apt-get upgrade, results in a 'Failed to fetch...':
. . . W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en_US Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
[...]
When I change my /etc/network/interfaces to:
auto eth0
iface eth0 inet dhcp
Everything works fine.
Looking into /etc/resolv.conf provides some more hints.
In cases where I was getting the resolving issue, resolv.conf was empty; no nameservers were specified. Then I changed to DHCP from static and restarted networking; /etc/resolv.conf got changed to: 'nameserver 192.168.1.1'.
Switching back from DHCP to static and restarting doesn't remove the nameserver entry. But when I restarted the system with static set, resolv.conf was empty. When I restart the system with DHCP set, resolv.conf has nameserver 192.168.1.1. So, it appears that the issue is that resolve.conf is not getting written to correctly? Which package/code is responsible for writing to resolv.conf? Is there a particular package that I can take a look at open issues?
UPDATE: istream posted a good article discussing changes to resolve.conf in 12.04. http://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libboost-python-dev : Depends: libboost-python1.46-dev but it is not installed
E: Unmet dependencies. Try using -f.

Any idea on how to remedy this?
I'm trying to add a command to be executed after logging into ubuntu. Specifically, xinput set-prop 11 "Device Enabled" 0.
What is the file that is sourced/executed when logging into a user session?
