The problem is with the update-alternatives --remove-all op-panel line in /var/lib/dpkg/info/op-panel.prerm
"set -x" added to /var/lib/dpkg/info/op-panel.prerm: # aptitude remove op-panel [snip] The following packages will be REMOVED: op-panel 0 packages upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

Removing op-panel ... + case "$1" in + update-alternatives --remove-all op-panel No alternatives for op-panel. dpkg: error processing op-panel (--remove): subprocess pre-removal script returned error exit status 1 Commenting out "update-alternatives --remove-all op-panel" allowed package removal. Installing and subsequently removing op-panel is now ok. Possibly that line needs modification. Regards, Jim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
