A regular reader of It’s FOSS, Chetan Jain contacted me today with this question: How can I fix **“Cannot add PPA” error in Ubuntu**. Chetan was trying to install [TLP (power management tool to reduce overheting)](https://itsfoss.com/reduce-overheating-laptops-linux/) and encountered this error:

**chetan@Inspiron-3521:\~$ sudo add-apt-repository ppa:linrunner/tlp**  
**Cannot add PPA: ‘ppa:linrunner/tlp’.** 
**Please check that the PPA name or format is correct.**

If you encounter similar error while adding a PPA in Ubuntu or Linux Mint, don’t worry. It’s one of the (less) common issue with PPA and can be solved easily.

Highly Recommended

I highly recommend reading this [detailed article on what is PPA](https://itsfoss.com/ppa-guide/), why is it used, how it works. This will give you a better understanding of PPA.

## Fix Cannot add PPA error in Ubuntu and Linux Mint

[![Cannot add PPA Ubuntu 14.04](https://itsfoss.com/content/images/wordpress/2014/05/PPA_Error_Ubuntu.jpeg)](https://itsfoss.com/content/images/wordpress/2014/05/PPA%5FError%5FUbuntu.jpeg)

There can be mainly two reasons behind this kind of error. Either the CA certificates on your system are broken or there is a proxy set up in your network.

Let’s first try to reinstall the CA certificates:

```
sudo apt-get install --reinstall ca-certificates
```

If the above command doesn’t work, perhaps there is proxy settings involved. To pass proxy settings to sudo, use it with E option in the following manner:

```
sudo -E add-apt-repository ppa:linrunner/tlp
```

This will get the PPA working. Chetan’s issue was solved with the second solution. I hope this quick tip help you as well to get rid of the PPA error. Any questions or suggestions are always welcomed.
