Hi,
I don't think that I am the only one which has this issue.
When I try to install mod_spdy, I've got some dependencies issues.

Here is the output :

$ dpkg -i mod-spdy-beta_current_amd64.deb 
Selecting previously unselected package mod-spdy-beta.
(Reading database ... 111842 files and directories currently installed.)
Preparing to unpack mod-spdy-beta_current_amd64.deb ...
Unpacking mod-spdy-beta (0.9.4.3-r420) ...
dpkg: dependency problems prevent configuration of mod-spdy-beta:
 mod-spdy-beta depends on apache2.2-common; however:
  Package apache2.2-common is not installed.

dpkg: error processing package mod-spdy-beta (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 mod-spdy-beta

I even tried to downgrade apache to 2.2 but the digital ocean mirrors doesn't provide that version unfortunately.

If anyone has a clue how to fix this issue, please let me know,
Thanks
