Bug#25398: dpkg dies if /usr/local/bin is a symlink
Package: dpkg
Version: 1.4.0.23.2
This is a problem that I helped fix on the #debian irc channel,
while we got the user up and going, it is probably something that
shouldn't happen.
If /usr/local/bin is a symlink like
lrwxrwxrwx 1 root root 20 Aug 1 12:50 bin -> /usr/lib/oss/soundon
Then dpkg dies with "not a directory".
Like
dpkg (subprocess): failed to exec dpkg-split to see if it's part of a multiparter: Not a directory
dpkg: error processing apt_0.1.5.deb (--install):
subprocess dpkg-split returned error exit status 2
D000010: ensure_pathname_nonexisting `/var/lib/dpkg/reassemble.deb'
Errors were encountered while processing:
apt_0.1.5.deb
This happens with dpkg-split (which is called by dpkg -i blah.deb)
and dpkg-deb -I blah.deb
An strace (grepping for directory) of dpkg-deb -I gives:
open("/etc/ld.so.preload", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
stat("/tmp/00335aaa", 0xbffffbb0) = -1 ENOENT (No such file or directory)
[pid 336] execve("/usr/local/sbin/rm", ["rm", "-rf", "/tmp/00335aaa"], [/* 16 vars */]) = -1 ENOENT (No such file or directory)
[pid 336] execve("/usr/local/bin/rm", ["rm", "-rf", "/tmp/00335aaa"], [/* 16 vars */]) = -1 ENOTDIR (Not a directory)
OK, so the problem looks like you do your execve, if it ENOENT you
keep going, but if it is ENOTDIR then you die. I suspect this may
not be what you want to happen.
The user's path was
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin
The quick fix was to cd /usr/local ; rm bin ; mkdir bin, that worked.
