Bug 515564 – sys-kernel/aufs-sources-3.12.20 file collisions

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Dustin J. Mitchell 2014-06-27 23:58:26 UTC]

The message below basically says don't file a bug unless I understand the message.  I understand the message, so I'm filing a bug.  As far as I can tell, this package is conflicting with itself.  I can't simply ignore the collision since it causes the emerge to fail.

ERROR: preinst
This package will overwrite one or more files that may belong to other
packages (see list below). You can use a command such as `portageq
owners / <filename>` to identify the installed package that owns a
file. If portageq reports that only one package owns a file then do
NOT file a bug report. A bug report is only useful if it identifies at
least two or more packages that are known to install the same file(s).
If a collision occurs and you can not explain where the file came from
then you should simply ignore the collision since there is not enough
information to determine if a real problem exists. Please do NOT file
a bug report at http://bugs.gentoo.org unless you report exactly which
two packages install the same file(s). See
http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to
solve the problem. And once again, please do NOT file a bug report
unless you have completely understood the above message.

ugh, doesn't fit in a comment on its own, even.. maybe 16k is too small?

Don't use external paste sites. Just attach it.

No package claims those files, so there is no file collision between packages in the tree. How those files and directories got there is something only you know.

I guess you didn't understand the message after all.

[Comment 3 Dustin J. Mitchell 2014-06-28 12:57:37 UTC]

The ebuild itself installed them -- something must have failed to record that correctly.  Either a bug in the ebuild or in portage?

[Comment 4 Jeroen Roovers (RETIRED) 2014-06-28 13:00:35 UTC]

I doubt it. Also, you didn't provide a build log for either merge and you didn't post your `emerge --info' output either.

Well, you managed to pose an imposible challenge, since Gentoo doesn't actually keep logs of merges, and obviously I've closed my terminal session since the first merge on June 8 so it's not in scrollback.

Your kindness overwhelms me.
