new ubuntu user here. I installed pdftk-java using sudo-apt, and it changed a lot of my root certificate authorities. Is this bad? I don't understand why this root certificate authority is needed by a PDF editing software/program. I'm not sure if I accidently installed malware, and how to get rid of it.

Here is my product release:

No LSB modules are available.
Distributor ID: Ubuntu

sudo apt install pdftk-java

You snipped out the single line that would have answered this. Immediately before Adding debian:ANF_Secure_Server_Root_CA.pem was probably the line Setting up ca-certificates-java (20190909) ....

This indicates that the output following (all the "Adding debian:") lines came from the processing of the ca-certificates-java package. Further up in the output you'll notice ca-certificates-java in the section of output "The following additional packages will be installed".

So, it's not pdftk-java specifically which added/replaced/updated the certificate files, but a dependency of it. As pdftk-java is a java application, the packagers determined that when installed, it should recommend a java runtime, which subsequently requires the certificates accessible to the java runtime in the java keystore.

So in summary, installing pdftk-java then pulled in default-jre-headless which pulled in ca-certificates-java which pulled in ca-certificates (which you already had).

So, no, not malware, not anything to be worried about. This is all working normally.
