Is ~/dotdeb.gpg safe to delete?

Question

I have a file called dotdeb.gpg in my root user's home folder. Would removing this file break the system, is it required?

Answer 1

It's most likely safe to remove. If you take a look at root's bash history you might see that it was downloaded and imported so the Dotdeb repository could be used.

From the Dotdeb website:

3. Fetch and install the GnuPG key

wget https://www.dotdeb.org/dotdeb.gpg
sudo apt-key add dotdeb.gpg

If you want to be safe compare the md5sum of the local file to the one on their website to verify that is where it came from.
