How to get recursively dependencies for package with versions? [on hold]


How to get recursively dependencies for package with versions? [on hold]



I need to install a package on a system without internet access (the package contains a driver for network card).



System A has internet connection and runs Ubuntu 14; System B has no internet connection and runs Ubuntu 16.



How can I download all dependencies recursively with the correct version on system A, that could be next installed on system B?

I would suggest that you run a docker container (or some type of virtualization) with Ubuntu 16.04 on System A. After that, you can update the packages index (apt update) then install the desired packages on that system. Finally, you may copy the packages index from /var/lib/apt, and the packages themselves from /var/cache/apt/archives to System B.


apt update


/var/lib/apt


/var/cache/apt/archives





Yet better, he may simply save the whole Docker container as an image file and run that image on the offline host. Containers have been found exactly for such cases to avoid dependency hell.

@MohammedNoureldin but he needs to install docker on System B in the first place.

@Abdullatif Eymash I used apt-get --download-only inside virtualbox with image of system B, then i copied apt cache to real system B and installed packages by dpkg. Problem solved THX

It's a good practice to restrict hosts from internet access. However, as a patch management solution, you should setup a local mirror - this will centralize your patching needs for the entire organization. It's not just limited to ubuntu but you could host multiple linux distro mirrors. The only thing you really need is a large capacity disk, maybe mirror it for some non-critical resiliency. This will also cut-back on a multi-server environment using bandwidth, limiting the bandwidth to a single host pulling updates to it's mirror one-time. Just make sure you have a process or script to run to regularly check for updates. That way your hosts are ready for patching when you need it, assuming you stay on top of emerging threats and vulnerability management for various *Nix platforms.



I'm not a huge fan of reinventing the wheel so.. here's a couple how-to references.



What you're going to have to do afterwards is change your /etc/apt/sources.list to point to your new internal repository for aptitude repos. You can just copy the lines existing there, change the server domain name to your local server. Then you don't need any of your linux hosts to communicate to any hosts outside of your network, the one server pulling from the mirrors can. It will definitely help you refine your security needs.



For RHEL based or yum, it's configured in /etc/yum.repos.d/{reponame}.repo

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".
