Feature changed by: John Thomas (john_tomas) Feature #305305, revision 5 Title: 1-click uninstall
openSUSE-11.2: Evaluation Priority Requester: Important
Requested by: Michael Loeffler (sprudel24) + Interested: John Thomas (john_tomas) Partner organization: openSUSE.org
Description: An easy way to remove Software! For example: you installed an application with "1-click install" (which will install all the packages that you need), there should be an easy way (also with 1 click) to remove what you have installed with that 1-click operation... in another words: an "1-click Uninstall" to remove installed software (dependencies and packages included).
Discussion: #1: Marek Stopka (m4r3k) (2008-09-16 17:56:55) This need support in libzypp... First needed feature is history of installation... should be ready before 11.1 release, but fully support will not be done before release, as far as I know... Imagine.. why we need history of installation You will install package fooA which need libfooA and libfooB. With installation of fooA, libfooA will be installed and libfooB will not be installed because it is already installed because user type zypper install libfooB before (he is a developer and libfooB is needed for his program which is not handled via package management). Now when you want remove all packages which was installed with fooA you can't tell if you should remove fooA, libfooA and libfooB or only fooA, libfooA, because you don't know (at this point) if libfooB was installed as fooA dependency or not.. So we need history of installation, after that it is just about solving dependency graph with sat solver. But 11.2 sounds realistic, I guess... This should not be only a 1-click install/uninstall feature, this should be implemented in libzypp as "remove_unneeded_dependency" and here should be possibility to do this clean up by 1-click uninstall, zypper and yast. It also should be configurable in /etc/zypp/zypp.conf so zypper, 1-click uninstall and YaST can remove all unneeded dependency automaticky. But when it is forbidden in configuration file user still can click on button in YaST (1-click uninstall can ask user during every uninstallation, if not configured as "remove every unneeded dependency automatically"), or just type zypper clean-my-mess : -) (maybe more smart name for this action :-) )
#2: Jan-Simon Möller (dl9pf) (2008-09-17 09:58:22) Good point, Marek! This is the way to go. Just a note/question: * can we already detect what 1-click-packages are installed? * if yes: we could for now show a list of the 1-click-packages itself and remove them (for now without the dependencies - I know, this is windoze-like)
