Installed Percona-Toolkit, but no sign of xtrabackup I've installed Percona-Toolkit on my Debian (Wheezy) test Server, using 

dpkg -i percona-toolkit.deb
apt-get install --fix-missing -f
dpkg -i percona-toolkit.deb


However, there is no sign of Innobackupex in the /usr/bin folder. Trying to run it simply gives me Command Not Found

I can see all the pt-xxx applications in there suggesting the installation worked ok.

I then tried

apt-key adv --keyserver keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A


as per the documentation, but that resulted in:

. . .
gpgkeys: key 1C4CBDCDCD2EFD2A not found on keyserver    
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0


Followed by

apt-get install xtrabackup


But that gave me

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package xtrabackup


How can I get xtrabackup (Innobackupex) installed as well?
It turned out to be an issue with our Proxy Server, blocking downloads from percona.com

Running sudo apt-get update revealed that every connection to percona.com 'failed', and so I got that added to the approved list, and after that it installed fine.
