Bugzilla Bug 194081

While emerge depcleans unmerge action the following backtrace occurred:

 --- !empty   dir /var/www
 Traceback (most recent call last):
   File "/usr/bin/emerge", line 6529, in ?
     retval = emerge_main()

I get this only on the unmerge phase of an installed package, that is not
during  cleaning of an older version ( emerge: ... merge foo-1.1 -> clean
foo-1.0 )

*** Bug 194083 has been marked as a duplicate of this bug. ***

Exact same thing here (-C gentoo-sources) on ~x86, portage 2.1.3.10.

Created an attachment (id=132105) [details]
ignore EBUSY during unmerge

If this patch is saved as /tmp/ebusy.patch, then it can be applied as follows:

patch /usr/lib/portage/pym/portage.py < /tmp/ebusy.patch

I've masked portage-2.1.3.10 to prevent others from hitting this bug.

This has been released in 2.1.3.11.

FIXED?
