How can I get a version of Tails (Tails or TAILS?) without the desktop GUI environment installed? If I can't, then how can I manually uninstall the desktop?
Currently it seems not possible to do this. Tails is thought to be a live operating system for an end user. While you can remove all the GUI features (
apt purge …), they'll be present at the next reboot.
However at the moment you can't get such a version of tails.
