Based on the info you provided, I would expect a *minimal* /etc/apt/sources.list file to contain something like: deb http://192.168.1.40:9999/debian/ stretch main deb http://security.debian.org/debian-security stretch/updates main if you want to use approx, assuming 192.168.1.40 is the IP address of your approx server. The actual file contents depends on choices made during installation. I have used approx for many releases. But I've never used Synaptic. I suggest to avoid using Synaptic until you have fixed command-line apt. Synaptic might be what caused the problem. So while troubleshooting this problem, I suggest running 'apt-get update' as root, and defer running Synaptic until that command completes without error. I don't think 'approx' is responsible for the error message you provided. It appears to be a permissions problem of apt-get failing to read a local file /etc/apt/trusted.gpg On stretch, I don't have that file. I had to go back two releases to wheezy to find an example. It is readable only by root. $ ls -l /mnt/p/B/etc/apt/trusted.gpg -rw------- 1 root root 1252 2013-07-03 21:49 /etc/apt/trusted.gpg So, I wonder what is going on? I'm not familiar with the contents of that file. That's why I suggest to remove Synaptic from the troubleshooting process, until apt-get is working. As a first step, I would create a /etc/apt/sources.list that does not use approx, and test it with 'apt-get update'. It would contain this: deb http://deb.debian.org/debian/ stretch main deb http://security.debian.org/debian-security stretch/updates main
