Ubuntu: Error Message while installing php5-intl


When I try to install php5-intl, I got this error message. What does mean of this message? Anybody can help me to explain this message? Should I remove php5-common first? or anything else?

There is something wrong in your APT sources.

You can see that because of the version of your php5-common packages which is 5.5.9+dfsg-1ubuntu4.4 whereas you php5-intl package version is only 5.5.9+dfsg-1ubuntu4.

Also, your current php5-common package version comes from /var/lib/dpkg/status indicating it can not be associated to any currently known APT source.

Therefore, it could mean that you used an APT source to install php5-common and removed it after then, or that your package lists are not up to date.

I recommend:

  • checking your /etc/apt/sources.list
  • running apt-get update (it should be done before installing any package)


According to the error message, it may be because you choose to hold some packages, forbidding them to get upgrades.

You can check for hold packages with these commands:

  • If you are using aptitude: aptitude search "~ahold"
  • If you are using apt-get: dpkg --get-selections | grep 'hold$'
