I have pointed apt to the said mountpoint but now it tells me W:The repository 'cdrom://[Debian GNU/Linux testing_Stretch_-Official Snapshot amd64 DVD Binary-1 [[date/time]] stretch Release' does not have a Release file. W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use. W:See apt-secure(8) manpage for repository creation and user configuration details. I guess I have to look for such a release file in the repositories and download it. Or is there any other solution you'd consider? By the way, there isn't any Stretch related key in the /etc/apt/trusted.gpg.d file invoked by apt-key list. Maybe I have to search manually for that key. But the DVD.iso should have any form of Release file, shouldn't it? Have a sunny nice saturday Stephan
