问题
I have this older package in this exact version that I want to install on Ubuntu.
https://launchpad.net/ubuntu/+source/php5/5.3.10-1ubuntu3.20
How can I install it using apt-get ? Thank you
回答1:
to find out what different versions of a package is available in the enabled repository
apt-cache policy <package-name>
in your case
apt-cache policy php5
select the version that you want to install and then type
sudo apt-get install pkgname=version
in your case
sudo apt-get install php5=5.3.10-1ubuntu3.20
before running any of the above commands, it is better to update the apt-cache first. To do it, run
sudo apt-get update
