Bug 19741 – Emerge crashes while trying to unmerge gentoo-sources

• Product: Portage Development
• Status: RESOLVED WORKSFORME

[Description Joshua J. Berry (CondorDes) (RETIRED) 2003-04-21 21:36:17 UTC]

Attempting to unmerge gentoo-sources-2.4.20-r3 causes emerge to die with a
Python IOError.

Things on my system are prelinked, although it's been a while since I've run the
command to make sure everything is prelinked properly/up-to-date.  (I just did
an 'emerge -u' today, but it's been well over a month since my last prelinking.)

Here's the output from my "emerge info":

Reproducible: Always
Steps to Reproduce:
1. emerge gentoo-sources
2. emerge unmerge gentoo-sources
Actual Results:  
Here's the Python backtrace:

Traceback (most recent call last):
  File "/usr/bin/emerge", line 1699, in ?
    if 1==unmerge(myaction, myfiles):

    retval = fchksum.fmd5t(prelink_tmpfile)
IOError: [Errno 2] No such file or directory: '/tmp/portage-prelink.tmp'


Expected Results:  
Unmerged gentoo-sources properly...

To work around this, I deleted /usr/src/linux-2.4.20-gentoo-r3, and unmerged
gentoo-sources.  It couldn't find any of the files to delete (obviously), but it
did unmerge successfully.

I am not able to duplicate this. It looks to be the result of
a failed copy, but I can't verify this. 

[Comment 2 Marius Mauch (RETIRED) 2003-09-30 12:16:39 UTC]

still a problem ?

[Comment 3 Joshua J. Berry (CondorDes) (RETIRED) 2003-09-30 13:02:33 UTC]

AFAIK, no.  I didn't even know this bug was still open...it was from a long
time ago.  Resolving as WORKSFORME, because, well, it does. ;)
