DOWNGRADE Zoneminder

Post by zemerdon »

How to know the version of installed package?
apt-cache policy <package name>

The above command will shows installed package version and also all the available versions in the repository according to the version of Ubuntu in which you are running.It doesn't display the package version which was intended for another version of Ubuntu(not your's).

Example:
$ apt-cache policy gparted

gparted:
Installed: 0.16.1-1
Candidate: 0.16.1-1
Version table:
*** 0.16.1-1 0
500 http://ubuntu.inode.at/ubuntu/ saucy/main amd64 Packages
100 /var/lib/dpkg/status

So the installed gparted version is 0.16.1-1.

How to install a specific package version?
sudo apt-get install <package name>=<version>

Example:
$ sudo apt-get install gparted=0.16.1-1
