Yume script broken on admin node of cluster
Hi I am running a ICE cluster which uses OSCAR.
I need to update various nodes and the update is failing for the lack of updated meta data information for the RPMS.
I tried running yume --prepare --repos which usually refreshed the metadata information.
But now it just gives out this 'dumb' output
***********************************************************************************************
pepper:/var/lock/systemimager # yume
Unexpected error detected (255) while distro-query. Exiting.
*****************************************************************************************************************************
I did some debugging using the perl debugger and reading through the perl script.
I could isolate the problem code snippet. Now I am new to both perl and to Cluster on Linux.
So correct me if you guys find anything wrong.
so the code snippet is here
*****************************************************************************************************************************
449 sub get_default_repos {
450 # if OSCAR_HOME is defined, we're on an OSCAR cluster
451 if (&on_oscar_master()) {
452 my $dquery = "$ENV{OSCAR_HOME}/scripts/distro-query";
453 if (-x $dquery) {
454 if ($installroot && (-x "$installroot/bin/bash")) {
455 $dquery = $dquery . " --image $installroot";
456 }
457 print STDERR "Executing: $dquery\n" if ($verbose);
458 local *CMD;
459 open CMD, "$dquery |" or die "Could not run $dquery: $!";
460 while (<CMD>) {
461 chomp;
462 if (/Distro package url : (\S+)$/) {
463 push <at> repos, split(",",$1);
464 } elsif (/OSCAR package pool : (\S+)$/) {
465 push <at> repos, split(",",$1);
466 }
467 }
I think that highlighted IF condition is failing

I could not establish the value of $installroot and $dquery. When I tried to print the value out, Perl complained that they are not initialized yet.
I checked the syntax of the script and it looks correct
I ran perl -c yume and it came out fine.
so I am stuck and need to get this script working. I believe the problem is with the call it is trying to make.
In short I want to get
yume --prepare --repos working.
