• Status: RESOLVED FIXED
• Product: Portage Development

[Description Martin von Gagern 2009-09-26 14:18:08 UTC]

Running an "emerge @preserved-rebuild" crashed for me:

# emerge --version
Portage 2.2_rc41 (default/linux/x86/2008.0/desktop, gcc-4.3.4, glibc-2.10.1-r0, 2.6.30-gentoo-r5 i686)

It might be that the ebuild it was about to emerge went away due to a portage tree sync in the background while this emerge process was busy with some other ebuild. A proper error message would be better than this backtrace, though.

It's fixed in svn r14442 to produce a message like this:

  ebuild not found for 'media-video/mplayer-1.0_rc4_p20090919-r1'

[Comment 2 Zac Medico 2009-10-04 00:20:03 UTC]

This is fixed in 2.2_rc43.

[Comment 3 Zac Medico 2009-10-11 01:08:50 UTC]

This is fixed in 2.1.7.
