이 패키지(pdfc-gui)가 Ubuntu 16.04에서 내 CA 인증서를 업데이트하는 이유는 무엇입니까?

다음 결과를 바탕으로 내가 설치한 애플리케이션이 신뢰할 수 있는지 확인하려고 합니다. 이것이 이 문제에 대한 조언을 얻을 수 있는 올바른 플랫폼이기를 바랍니다!

이 패키지를 설치했습니다(pdfc - 그래픽 사용자 인터페이스) 에서여기그리고:

sudo dpkg -i pdfc-gui-21.4.225.deb

설치하는 동안 SSL 인증서가 추가/업데이트된 것을 확인했습니다(아래 설치 출력 참조).
불행하게도 나는 이것이 내가 걱정해야 할 문제인지 알 만큼 리눅스를 잘 알지 못합니다.

누구든지 이 결과를 나에게 설명할 수 있나요?

이 패키지를 제거해야 하나요? 그렇다면 모든 변경 사항이 실제로 되돌려지도록 어떻게 보장할 수 있나요?
