In order to log into the WLAN of my University i need to download an updated version of the CA Certificate i downloaded last semester.



The problem i now got is that when i try to download it from the provided link i get a the following errormessage from my OS:



This certificate is already installed as a certificate authority.


I've already tried to mark them as unused in the ca-certificates.crt file, also to delete the symbolic links and actual .pem files from the directories but i either didnt delete the right one or it didnt work.



Any help is highly appreciated!
