It is not about the common download & install thing, what apt (aptitude, etc) does, it is a scripted download a package file.
I found the
dget tool for this task, which works quite well. But, unfortunately, it doesn't have any option to specify a different repository URL as it is given in the
Is it somehow possible? Actually, a
dget-like functionality would be the best, but where I can also specify the repo URL.
P.s. thank you very much the scripts, but I would like to prefer a debian tool for this very simple task. It will be part of a buildscript, for external usage, and any unneeded complexity has intolerable collateral costs. It must be done by a debian tool.
P.s.2. Finally I solved this with updating the system-wide repos, and downloading the packages with
dget. Thank you very much the scripts!
