/etc/ufw/applications.d has wrong syntax

Marking confirmed as I have seen this myself. I am not sure what is causing this as the version of ufw is the same in both Lucid and Maverick, and afaik lucid is not affected by this. Any help is appreciated.

Hm, could it be that the script tries to open "/etc/ufw/applications.d" as a file while it is a directory?
reinstalling ith with apt-get install --reinstall does NOT show the error again.

This is caused by this line in /var/lib/dpkg/info/ufw.config:
if dpkg --compare-versions "$2" lt 0.28-1 ; then

Apparently something changed between in dpkg between maverick and lucid and the 'config' file is being passed different arguments.

This bug was fixed in the package ufw - 0.30.0-1ubuntu1

what's the fix for this problem? I'd like to try your fix for my problem. thanks.

I got an error "dpkg: version 'uname -r' has bad syntax: version string has embedded spaces

when I tried to uninstall bootchart in ubuntu 10.10.

I found /var/lib/dpkg/info/bootchart.preinst has a similar line

if dpkg --compare-versions "$2" lt "0.90.2-1"; then
...

zebratt, from the changelog:
  * debian/postinst: don't source /usr/share/debconf/confmodule when $1 =
    triggered. Fix thanks to Colin Watson. (LP: #618410)

Looking at debian/postinst, ufw now has:
# Only source /usr/share/debconf/confmodule when not called with 'triggered'
# to avoid LP: #618410.
if [ "$1" != "triggered" ]; then
    . /usr/share/debconf/confmodule
fi

Thanks, Jamie.

I finally figured out a solution for my problen,=, although I still think the bug is still there, likely in bootchart. for some reason, `uname -r` may be written or executed as 'uname -r'.

the solution is delete the following garbage, then execute reinstall bootchart.

sudo rm /boot/initrd.img-uname
sudo rm /boot/initrd.img-uname -r
sudo rm /var/lib/initramfs-tools/uname
sudo rm /var/lib/initramfs-tools/uname -r
then, reinstall bootchart and pybootchartgui

at least, my apt-get works normal now.
