I was trying to install MemCached using this command: sudo aptitude install memcached, but I got the following error: sudo: aptitude: command not found.

After researching, I found out that Aptitude is an utility program to manipulate files, install out uninstall programs. I found several web pages explaining what Aptitude. However, I don't have the impression that any of them explains how to get Aptitude in the first place.

Is Aptitude already in Ubuntu so that I just need to enable it. Or should I download and install it?

Thanks for helping

  • sudo: aptitude: command not found is not a command. Copy & paste error? Just use sudo apt-get install memecached. – Raptor Sep 18 '14 at 02:14

    Different? More like the instructions you are following are incomplete. I prefer aptitude too but the default tool is apt-get. – tripleee Sep 18 '14 at 03:00

    Building dependency tree Reading state information... Done Package aptitude is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'aptitude' has no installation candidate

    This doesn't work on Ubuntu 16

You may need to update your sources first:

sudo apt-get update
sudo apt-get -y install aptitude
