I am Ozan, a Computer Engineering student.
First of all, I was using Debian 9 as the operating system in a project I was working on. But I'm using it by running it with a vagrant from the Debian 9 box file. When I switch to Debian 10 operating system, when I update proxy settings in vagrant's automatic configuration, apt-get commands do not work. Debian 9 did not have this problem.
My vagrant proxy set code is as follows:
config.proxy.http = "my proxy adress"
config.proxy.https = "my proxy adress"
The error instance I get is:
Thank you for your understanding and I wish you the best of luck.
