Installing on Ubuntu
PPA Purge is available in official Ubuntu repository, so you can install it by typing the following command:
How To Use PPA Purge
- sudo apt-get install ppa-purge
For example, you've upgraded Mozilla Thunderbird from PPA with this command:
To downgrade Mozilla Thunderbird from the above PPA, you should run this command:
- sudo add-apt-repository ppa:mozillateam/thunderbird-next
PPA Purge will automatically remove Mozilla Thunderbird which is installed from PPA and then install the "original" version of Mozilla Thunderbird from Ubuntu repository.
- sudo ppa-purge ppa:mozillateam/thunderbird-next
"Unfortunately, I forget what PPA I've used to install the app?" Well, you should make use of "history" command on Terminal combined with "grep" function. Here's the example:
The output of the above command is shown below
- history | grep add-apt-repository
Now you have a comprehensive list of "add-apt-repository" commands you've typed on Terminal. They can help you to remember what PPA you've used to install certain application.
