Thanks for reporting. The line that causes this error in the postinst script is: Code: adduser --system --disabled-password --disabled-login \ --home /usr/share/icecast2 --no-create-home --group icecast However, Maemo isn't shipped with adduser at all! Busybox-power does provide an adduser applet, but it takes different arguments than the postinst tries to use. The solution is rather simple though. Execute: Code: apt-get install adduser and icecast2 will install flawlessly . The postrm script also uses utilities from the adduser package (namely: deluser and groupdel), so you shouldn't uninstall the package right after installing icecast2. It seems like the package maintainer simply forgot to add a dependency on adduser to icecast2.
adduser --system --disabled-password --disabled-login \ --home /usr/share/icecast2 --no-create-home --group icecast
apt-get install adduser
