Bug 70989 – portage-2.0.51-r3 traceback with dangling symlink

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Aron Griffis (RETIRED) 2004-11-12 11:37:57 UTC]

portage blows up when it tries to overwrite a dangling symlink on installation.  Here's an easy way to demonstrate on a small package:

# ln -sfn bogus /usr/libexec/mozilla-launcher
# emerge mozilla-launcher
...
>>> Merging net-www/mozilla-launcher-1.22 to /
--- /usr/
--- /usr/libexec/
Traceback (most recent call last):

    elif stat.S_ISREG(mydmode) or (stat.S_ISLNK(mydmode) and stat.S_ISREG(os.stat(mydest)[stat.ST_MODE])):
OSError: [Errno 2] No such file or directory: '/usr/libexec/mozilla-launcher'

Be sure to fix it afterward, otherwise you'll next file a bug against me about mozilla-launcher. ;-)

# rm -f /usr/libexec/mozilla-launcher
# emerge mozilla-launcher

Fixed a while ago, but there was no bug. I'll attach the fix in a minute.

Hi Jason. Thanks for pointing me this way. I'll try the patch and report on my experiences with it.

[Comment 6 Lars Bröcker 2004-11-26 04:50:07 UTC]

Hi, the patch worked, xorg installed okay. Thanks :)

[Comment 8 Nicolas Vilz 2004-12-02 14:39:36 UTC]

thx. fixed my texi2html-problem on ~ppc

[Comment 9 Maik Danstedt 2004-12-03 02:58:18 UTC]

This worked fine for my problem with xorg. :-)

[Comment 10 Sascha Silbe 2005-01-11 01:19:57 UTC]

I'm having the same problem while installing lapack after unmerging lapack-atlas. Will file a separate bug about lapack-atlas leaving this link behind. Any idea when the fix will get into mainstream Portage?  

[Comment 11 Whit Blauvelt 2005-01-13 19:50:38 UTC]

Yes, patch necessary. Please mainstream. (This for openssl on a system that went some months between updates.)

[Comment 12 Aron Griffis (RETIRED) 2005-03-13 20:10:06 UTC]

Saw this again today, running portage-2.0.51.19 this time.  This instance was on a file /etc/._cfg*, so there might be some CONFIG_PROTECT magic mixed in.

[Comment 13 Jason Stubbs (RETIRED) 2005-04-14 06:52:48 UTC]

I sincerely doubt that it was the same bug. Please open a new one with the error if it happens again.
