I have a fresh install of Ubuntu 12.04.3 LTS

Ruinning cat /etc/apt/sources.list

shows:

deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse

but if I run sudo apt-get update && sudo apt-get install mlocate locate
I get

Package locate is a virtual package provided by:
  locate:i386 4.4.2-4ubuntu1 [Not candidate version]

E: Package 'mlocate' has no installation candidate
E: Package 'locate' has no installation candidate

Please help! I never realised how much I depend on the find command..

Cheers, Paul

Have you used sudo apt-get install mlocate:amd64? –  Braiam Nov 24 '13 at 17:02

2 Answers 2

Create the /var/lib/dpkg/arch file with the following text:

amd64
i386

Then do, sudo apt-get update and now you can start installing things again.

After further investigation it turns out this has been disabled by the hosting company.

By default mlocate is not installed, and disabled if it is installed by default. The reason for this is due to the cron tasks and IO load it puts on the servers which can impact other servers on the same host. IO is the biggest cause for slow down on hosts which is why we are fairly strict. We prefer to encourage people to use the find command to find things eg find / -iname "somename"

When trying to figure this out the first place I turned to was google, I was unable to find anything useful on this problem.

I have added this as an answer so that hopefully people Googleing "unable to install locate" in the future can know to ask their hosting company first!
