As you have configured the apt-cacher-ng server, Now you have to change the directory where the packages will be downloaded. This is to ensure that you will provide a directory which has large space to store files or packages. To change the current directory to a new directory you have to the following steps.
To change the path you have to edit the following configuration file
sudo nano /etc/apt-cacher-ng/acng.conf
Now change the value of CacheDir and also create a folder with owner ng-cacher-ng:ng-cacher-ng and the permissions for this folder as 2755. For this
sudo chown -R apt-cacher-ng:apt-cacher-ng /path/to/the/cachedirectory sudo chmod -R 2755 /path/to/the/cachedirectory
To import already downloaded packages, We have to create a folder inside the cachedirectory and copy all the contents from /var/cache/apt/archieves to /path/to/cachedirectory
sudo cp /var/cache/apt/archieves* /path/to/cachedirectory
Now you can open a browser and type this address on the address bar
And click the “Start import” button on this page.
Hope this Helps.
