I have a .crt certificate and I've tried installing it in .local/share/ca-certificates (I've created this last folder because It didn't exist) and put my ca.crt into it , then I executed this command :
And received this output :
Updating certificates in /etc/ssl/certs... 0 added, 0 removed; done. Running hooks in /etc/ca-certificates/update.d... done. done.
As I see 0 added 0 removed I think that the .crt didn't installed correctly . How should I install this .crt certificates ?
