Well, you could NFS share the download directory. You don't want that cleaned out when one machine does an install so use the "zypper --keep-packages" option for the repositories you want to share (see the "zypper modifyrepo" command for how to do this). -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Would be nice to have some option "zypper --keep-newer-packages", which removed older versions of a package whenever a new version of the same packages is downloaded. +1

I also like to have this also for repositories, which in rare case cause problems, such as Kernel:stable. Currently I use keeppackages=1 for Kernel_stable. If for instance my Nvidia driver does not compile against the latest Kernel I can manually downgrade the kernel from /var/cache/zypp/packages/Kernel_stable. Unfortunately there no function to cleanup the cache directories so, that only new packages are kept.

You probably need to explain what functionality you expect. I do not know what apt-offline does and my first reaction to this question was "boot off DVD". One use case is described in the blog article linked from my initial post:

"Let’s imagine the scenario: You have a Ubuntu machine at home that doesn’t come with any Internet connection (probably because home networking is /very/ expensive), and your office (or school) PC is connected to a broadband connection with blazingly fast speed. With apt-offline, you can now make use of the office or school PC (regardless it is running Linux or Windows) to download the necessary packages to your USB drive, and then bring it home to update your home computer." Source: https://www.maketecheasier.com/update-upgrade-ubuntu-without-internet-connec... A slightly different use case I saw in a German Linux group: One user has Internet access, but only with a low amount of data per month, let's say 500 MB per month. He downloads the Ubuntu (or openSUSE) DVD from his office computer with a good Internet connection and takes this DVD to his home computer to install Ubuntu. The question of this user was: How I can get the online updates in this scenario? Someone suggested apt-offline. And my question is, what someone can do, if I want to have something similar for openSUSE? One advantage of apt-offline is, that the office computer doesn't necessarily need Linux. A windows computer can download the packages too. Another use case is the following. I had this often as a Linux trainer: At the beginning of a Linux course, all participants, let's say 20 people, have to learn to install openSUSE on their PCs. The initial media can be delivered as DVDs, USB devices or as a network drive. (Network drive was usually faster than DVDs, but more difficult to set-up for beginners.) But how they get the online updates? Often this takes many hours or days, if everyone downloads and installs his own online updates. At least in the past openSUSE had an issue with libZypp/libCURL so that using a caching proxy to accelerate the downloads for many machines was useless. libZypp had configured libCURL so, that caching was disabled. With some tricks (I remember adding 'header "Pragma:"' to ~root/.curlrc) this issue could be worked around. I don't know, if this issue still exists. Another problem with the caching proxy solution was, that libZypp used mirrors, which makes caching ineffective too. So we have 2,5 use cases at the beginning.

I think apt-offline was developed after the success of APTonCD, http://aptoncd.sourceforge.net/ (you can use it on a flash drive, not only a CD). It was a Brazilian project at 2006, and was very useful because some regions in Brazil don't have a high speed connection. The problem is not only updating, but installing new software. It's very hard to do it without a internet connection (you need satisfy a lot of dependencies!). Atenciosamente / Best regards, Marcelo Atie. 2016-06-22 0:27 GMT-03:00 Andrei Borzenkov :

My second reaction remains - use DVD with next version and do either online or offline update with it.

Although ability to download updates only for a given package list is nice, and this is not the first time I see it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
