I figured out i got no folder named dpkg. I must have deleted it. Dont know if this helps. I tried to do this https://askubuntu.com/questions/3833...dpkg-directory , but it doesnt work for me, because i get the following output

Code:

$ apt-get download dpkg
Err:1 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 dpkg amd64 1.18.4ubuntu1.2
Could not open file /usr/bin/dpkg_1.18.4ubuntu1.2_amd64.deb - open (13: Permission denied) [IP: 91.189.88.152 80]
E: Failed to fetch http://archive.ubuntu.com/ubuntu/poo...u1.2_amd64.deb Could not open file /usr/bin/dpkg_1.18.4ubuntu1.2_amd64.deb - open (13: Permission denied) [IP: 91.189.88.152 80]

your link is broken.
i don't know what you did.
anyhow, don't just link to some askubuntu article, but SHOW us what you did, step by step.

what you did show suggests that
- you downloaded the package without superuser privileges, which i think is correct in this situation
- you are in the /usr/bin directory, for some reason (why?), for which you con't have write permission.

so just try again, but this time enter
before you issue that command.
