Want to install specific version of a package, or package from a certain software source? Here’s how to do the trick in Ubuntu & Debian via APT command.
There’s a few powerful graphical tools such as Synaptic package manager allow to specify which package version to install. However, for those familiar with Linux commands or Ubuntu / Debian Server without GUI, here’s how with APT command.
1. Refresh Package Cache:
After adding / removing software sources or changing the apt preferences, you have to update the system package cache before installing any package. To do so, simply run command:
sudo apt update
Depends on your system and software sources, it outputs something like this:
[email protected]:~$ sudo apt update [sudo] password for merilyn: Hit:1 http://deb.debian.org/debian bullseye-security InRelease Hit:2 http://ftp.us.debian.org/debian bullseye InRelease Hit:3 http://ftp.us.debian.org/debian bullseye-updates InRelease Hit:4 https://deb.opera.com/opera-stable stable InRelease Reading package lists... Done
2. Install Specific Version of a Package via APT:
Some software have different package versions available in the system, from either same or different sources. Usually, apt will install the package with higher version number. To install an old one, user may either change the package priority, or use the command below:
sudo apt install <package_name>=<version_number>
For instance, the command below will install the
phpmyadmin with version “4:4.9.5+dfsg1-2”.
sudo apt install phpmyadmin=4:4.9.5+dfsg1-2
Some app has packages for different CPU architectures. For example, you may try installing 32-bit VLC with version 22.214.171.124-1 on 64-bit machine via command:
sudo apt install vlc:i386=126.96.36.199-1
So, how do you know which versions are available? This command will tell you:
apt list --all-versions <package_name>
As it outputs below, I have two phpmyadmin package versions: “4:5.1.1+dfsg1-3+focal1” and “4:4.9.5+dfsg1-2”.
[email protected]:~$ apt list --all-versions phpmyadmin Listing... Done phpmyadmin/focal,focal,now 4:5.1.1+dfsg1-3+focal1 all [installed,local] phpmyadmin/focal,focal 4:4.9.5+dfsg1-2 all
3. Install Package from Certain Software Source:
It’s possible to specify which software source to install the package from. The command will be:
sudo apt install -t <software_source> <package_name>
Firstly, you need to find out the “<software_source>” to use in command. After running
sudo apt update to refresh package cache, check software sources via command:
apt-cache policy |more
This command tells all the software sources in system. Here I’m going to check the Phpmyadmin PPA, and the line below define the source in the picture:
“release v=20.04,o=LP-PPA-phpmyadmin,a=focal,n=focal,l=PPA for phpMyAdmin,c=main,b=amd64″
To be unique, I can use either “o=LP-PPA-phpmyadmin” or “l=PPA for phpMyAdmin” to specify the PPA source in apt command. So, to install phpmyadmin from the PPA using command:
sudo apt install -t "o=LP-PPA-phpmyadmin" phpmyadmin
sudo apt install -t "l=PPA for phpMyAdmin" phpmyadmin
That’s all. Enjoy!
