Bug 405505 – sys-fs/udev-init-scripts-8 collides with sys-fs/udev-175-r1

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alec Meyers 2012-02-24 04:08:09 UTC]

sys-fs/udev-init-scripts-8 (a dependency of udev-181) collides with the currently-installed sys-fs/udev-175-r1

>>> Installing (2 of 3) sys-fs/udev-init-scripts-8
 * checking 10 files for package collisions
 * 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). Once again, please do NOT file
 * a bug report unless you have completely understood the above message.

Sorry, but how do I up to >=udev-180 if >=udev-180 depends on udev-init-scripts-8, which collides with the currently installed version?

To be clear:
- sys-fs/udev-175-r1 is installed.
- I try to update udev to 181
- portage tries to install udev-init-scripts <-- collision
- sys-fs/udev-181 fails to install due to failed dependency

So there needs to be a blocker, or post-dependency, or something else to ensure that old udev gets unmerged before udev-init-scripts gets installed.

I'm reopening this.

emerge --unmerge (-C) forcefully uninstalls a package, disregarding dependencies. So you could use:

emerge -C udev
emerge '=udev-181'

Another possibility is to disable "protect-owned" and "collision-protect" in FEATURES temporarily when installing sys-fs/udev-init-scripts.

But I guess there indeed should be a blocker in sys-fs/udev-init-scripts.

Fixed in version 10 and 9999 by setting some more blockers
