I wanted to add some themes from sudo add-apt-repository ppa:noobslab/themes
. How do I ensure these are safe repos? They are listed in many blogs and answers, however is there an official place I could check for the risk of malware?
I actually added them and then removed them using
sudo apt-get clean
sudo apt-get remove
Am I safe after that usually? I also scanned my system using clamav and its fine. Perhaps I need to see the files that might have gotten installed to make sure there are no harmful scripts or binaries.
Do I need to re-install system to make sure I don't risk security issues with my data?
