@AlexTalker, а-ля ему нужен debhelper, которому нужен dpkg-perl, а он уже в свою очередь ругается, что у меня perl не под deb собран, в целом, удаляется очень легко, просто в папке alien прописать make clean

Ну вот во имя защиты и разберётесь как сделать так чтобы из репы ставилось.

удаляется очень легко, просто в папке alien прописать make clean

И заодно в том, что делает цель clean (спойлер: не деинсталляцию)

@AlexTalker, я знаю, что clean не для этого, но модуль uninstall там deprecated, и я попробовал методом тыка clean использовать, нет, он и правда не сработал, скорее всего до этого я alien, значит, ручками удалил
