Description Michael Schwendt 2002-11-20 10:56:24 UTC

Description:
The portmap package fails to uninstall.

Version-Release number of selected component (if applicable):
4.0-46

How reproducible:
Always

Steps to Reproduce:
1. rpm -evv portmap


Actual Results:  D: fini      100755  1 (   0,   0)      1901
/etc/rc.d/init.d/portmap
D:     erase: %postun(portmap-4.0-46) asynchronous scriptlet start
D:     erase: %postun(portmap-4.0-46)   execv(/bin/sh) pid 3049
+ '[' 0 -ge 1 ']'
D:     erase: waitpid(3049) rc 3049 status 0
D:     erase: %postun(portmap-4.0-46) asynchronous scriptlet start
D:     erase: %trigger(portmap-4.0-46)  execv(/bin/sh) pid 3050
+ /sbin/chkconfig --add portmap
error reading information on service portmap: No such file or directory
D:     erase: waitpid(3050) rc 3050 status 100
error: %trigger(portmap-4.0-46) scriptlet failed, exit status 1


Expected Results:  No such error.


Despite the package version of 4.0-46, it activates its own postuninstall
trigger which of course no longer finds the "portmap" service script (afterall
this is postun) and hence fails.

%triggerpostun -- portmap <= portmap-4.0-22
/sbin/chkconfig --add portmap

Comment 1 Michael Schwendt 2002-11-20 12:21:52 UTC

[Cc'ing Jeff Johnson, because it looks like RPM is involved.]

On Valhalla the postuninstall trigger is not called upon erasing the package:

D:   NO     A portmap = 4.0-41  B portmap <= 4.0-22

Comment 2 Need Real Name 2002-11-21 01:26:32 UTC

These switches can be used to remove
portmap until the RPM is fixed

# rpm -e --notriggerpostun --nopreun portmap

Comment 3 Milan Kerslager 2002-11-24 11:56:21 UTC

Please change '=' to '-eq' inside trigger and preun script (at least). The test 
for numerical value should be like:

if [ $1 -eq 0 ]; then

The char '=' is intended to use for string comparing only.

The problem persist in beta1 (8.0.90).

Comment 4 Michael Schwendt 2004-03-13 05:51:15 UTC

Filed 2002-11-20, I cannot reproduce it with Fedora Core 1.
