Adding Debian 10.3 isos to APT sources.list with cert
by bruceam from LinuxQuestions.org on (#521A9)
In earlier versions of Debian, I would download the Debian isos, and mount them to specific directories on the hard drive. I would then add them to the "sources.list" file so the computer would not ask me to load the discs into the optical drive every time I ran 'apt'. I added them to sources.list in the following manner:
Code:deb file:/home/abc/isos/disc01 buster contrib mainWhen I upgraded to Debian 10.3, I did the same thing, but now it doesn't work. When I point "sources.list" to the directory where the isos are installed, an apt command returns the following:
Code:E: The repository 'file:/home/abc/isos/disc01 buster Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.I have been to the "apt-secure(8)" manpage, but I have no idea what to look for. It was like reading tax code.
Can anyone tell me what is going on, what I am doing incorrectly, and how do I fix it?
