From 484babb7d00f7550cbaa592b7cb0022d38217fad Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Mon, 28 May 2018 17:02:17 +0200 Subject: Don't show acquire warning for "hidden" components Commit d7c92411dc1f4c6be098d1425f9c1c075e0c2154 introduced a warning for non-existent files from components not mentioned in Components to hint users at a mispelling or the disappearance of a component. The debian-installer subcomponent isn't actively advertised in the Release file through, so if apt ends up in acquiring a file which doesn't exist for this component (like Translation files) apt would produce a warning: W: Skipping acquire of configured file 'main/debian-installer/i18n/Translation-en' as repository 'http://deb.debian.org/debian buster InRelease' doesn't have the component 'main/debian-installer' (component misspelt in sources.list?) We prevent this in the future by checking if any file exists from this component which results in the warning to be produced still for the intended cases and silence it on the d-i case. This could potentially cause the warning not to be produced in cases it should be if some marginal file remains, but as this message is just a hint and the setup a bit pathological lets ignore it for now. There is also the possibility of having no file present as they would all be 0-length files and being a "hidden" component, but that would be easy to workaround from the repository side and isn't really actively used at the moment in the wild.
