- repository - How to search for an official PPA? - Ask Ubuntu

- security - Are PPAs safe to add to my system and what are some red . . .
Dev PPAs are the safest route and also need to see the contributor's duration at Launchpad These factors guarantee a safe, stable system using PPAs for latest programs

Are PPA's safe to add to my system and what are some "red flags" to watch out for? ( thanks @LostInBrittany ) Is there any guarantee that software from Launchpad PPAs is free from viruses and backdoor threats?
- How can I get a list of all repositories and PPAs from the command line . . .
I know how to list all packages installed on my system But how could I get a list of all repositories and PPA's into a script that I can run on a new machine to replicate the repository setup inc
- apt - State of PPAs after a distribution upgrade - Ask Ubuntu
Revisit these PPAs in a few months to see if the new release is supported 6) Edit and re-add the PPAs that you want to keep, and that have compatible packages for your new release Re-add each PPA one at a time, including separate update upgrades for each PPA Watch your apt output carefully for errors and warnings
- Is it safer to purge PPAs before upgrading to a new Ubuntu release?
Yes it safer to remove PPAs and their packages Ubuntu upgrades are tested for default installations, not installation in which everything is changed by PPAs By removing extra repositories (not just PPAs, but also third party repositories) and their associated packages, you return the system to their original state After the upgrade, you're free to install your preferred PPAs of course
- apt - How can PPAs be removed? - Ask Ubuntu
The PPAs (repositories) themselves will be listed under the 'Other Software' tab of the Settings->Repositories menu They can be removed just like any other source
