pacman -R usbmuxd error

I don't know if it's a bug in pacman or in usbmuxd packaging, so I'm posting here instead of filing a bug report...

> sudo pacman -Rns libimobiledevice
checking dependencies...

Remove (4): libimobiledevice-1.0.1-1  usbmuxd-1.0.4-2  libusb1-1.0.8-1
            libplist-1.3-1

Total Removed Size:   1.99 MB

Do you want to remove these packages? [Y/n]

I tried to add the 'v' option (verbose) to pacman but that didn't add any information about the error. pacman.log contains no more info either.

In fact, the problem seems to be with usbmuxd:

Re: pacman -R usbmuxd error

Seems like this package has an install script, which needs a package which is not installed. Here's the install script

post_install() {
    getent group usbmux >/dev/null 2>&1 || usr/sbin/groupadd -g 140 usbmux
    getent passwd usbmux >/dev/null 2>&1 || usr/sbin/useradd -c 'usbmux user' -u 140 -g usbmux -d / -s /sbin/nologin usbmux

    usr/bin/passwd -l usbmux &>/dev/null
}

pre_upgrade () {
    if [ $2 == "1.0.4-1" ]; then
        pre_remove $1
    fi
}

post_upgrade() {
    post_install $1
}

pre_remove() {
    getent passwd usbmux >/dev/null 2>&1 && userdel usbmux
    getent group usbmux >/dev/null 2>&1 && groupdel usbmux
}

Now it's  your turn to find out what's the culprit here.

Re: pacman -R usbmuxd error

pre_remove() {
    getent passwd usbmux >/dev/null 2>&1 && userdel usbmux
    getent group usbmux >/dev/null 2>&1 && groupdel usbmux
}

well... the error is happening pre removal of the package...  so pre_remove seems the place of the error!

I can not see anything standing out at me as being wrong there.

Give what you have. To someone, it may be better than you dare to think.

Re: pacman -R usbmuxd error

pre_remove() {
    getent passwd usbmux >/dev/null 2>&1 && userdel usbmux
    getent group usbmux >/dev/null 2>&1 && groupdel usbmux
}

The function is returning false.

fn() { getent group bogusgroup && groupdel bogusgroup; }
fn &>/dev/null
echo $?
2

Re: pacman -R usbmuxd error

This is still present  (and quite confusing)
