<Solved> Fritzbox certificate how to install

Hello all,
I have a Fritzbox router which can generate a certificate for use on my system.
My question: how do I install that box.cer file?
My system is a Linux Mint 18.1 MATE 64bit.
I'ld like that certificate installed so when I ftp to the Frithbox via filezilla it doesn't complain about the missing certificate anymore.
Hope someone knows and can help.

Here is the URL regarding Fritzbox certificates for the 7390:
https://en.avm.de/service/fritzbox/frit ... -computer/
If you have a different model you will have to ask the manufacturer AVM or access the knowledge base at the URL above.
Addendum: The instructions to install "boxcert.cer" given in the URL above were most probably written for an older version of Firefox. To install boxcert.cer in Firefox 58.0.2 access the "Privacy & Security" setting via Edit, Preferences.

Thanks for your answer.
In the article you linked it says:
Import the certificate to the computer's certificate administration. ... The manufacturer of the Linux distribution ... can provide you with information on importing certificates.
That's what I need ... only I don't know how to do that.
Firefox is not the problem. it's filezilla that complains about the missing certificate. So each time I want to ftp to or from my Fritzbox I have to click that warning away ... which is annoying.
Maybe someone here knows and can help.
Cheers O-rion

Certificates are added to the system as superuser.
Move the file boxcert.cer to /usr/local/share/ca-certificates and then run sudo update-ca-certificates
Firefox has its own ca-certificates separate from the operating system.

Turned out today that it didn't help :-(. Just worked for one day ( probably because filezilla has a cookie for that somewhere)
When running
the output is:
Code: Select all
Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.
done.
Reads to me that nothing is added.
Tried those locations as well ... still it said nothing was added.
What else could I try?

You could try adding the boxcert.cer file to /etc/ssl/certs/ca-certificates.crt
Follow with sudo update-ca-certificates

no luck up to now ...
So I'll probably give up on that one.

The information in the following URL may explain it better:
https://superuser.com/questions/437330/ ... -to-ubuntu
There is quite a lot of information available on-line on this subject.

Finally managed to get the certificate imported.
Had to rename it to boxcert.crt.
Still Filezilla only accepts it for the day. Next day it asks again. So there must be a problem with Filezilla still. I'll investigate that further in their forum.
Thanks kyphi for your help ... and patience.

Two thoughts:
1. Have you checked and adjusted the permissions of boxcert.crt - right click on the file and look in properties.
2. Have you considered using another ftp programme ? As I understand it Filezilla is not being maintained.
