為什麼無法在 Raspbian 中刪除使用者？
我在 Raspberry Pi 3b 的 Raspbian Jessie 中取得了成功

pi在刪除目前程序後，它總是為使用者創建一個新程序。你怎麼能防止這種情況發生？成功的嘗試$$ Stephen $$
做
masi@raspberrypi:~ $ sudo systemctl stop autologin@tty1 masi@raspberrypi:~ $ ps -fu pi UID PID PPID C STIME TTY TIME CMD masi@raspberrypi:~ $ sudo deluser pi ... masi@raspberrypi:~ & sudo vim /etc/passwd ... pi no longer here! masi@raspberrypi:~ & sudo deluser -remove-home pi問題的解決方案在這裡
locale的執行緒中。替換
autologin-user=pi為autologin-user=masiin/etc/lightdm/lightdm.conf。如何成功刪除pi使用者？
您的
pi使用者已登錄，在tty1; 您應該在刪除使用者之前將其註銷。（該menu-cached程序被 LXDE 桌面環境使用。可能還有其他程序正在為使用者執行pi。）如果您無權訪問 GUI 以將使用者註銷（即，您正在遠端訪問 Raspberry Pi），最安全的選擇可能是停止桌面管理器：
sudo service lightdm stop（假設您使用的是 LXDE 預設值）；這應該殺死所有
pi的程序。您還需要停用自動登錄 (
login -f)。如果你有一個 old-style
inittab，編輯你的/etc/inittab文件，並替換看起來像這樣的行1:2345:respawn:/bin/login -f pi tty1 </dev/tty1 >/dev/tty1 2>&1（重要的部分是
/bin/login -f pi tty1）1:2345:respawn:/sbin/getty 115200 tty1然後
init通過執行重新載入sudo telinit q使用用於自動登錄的 systemd 單元，例如您的
autologin服務，禁用該服務：sudo systemctl --now disable autologin@tty1這也將停止設備並重新載入 systemd 配置。
此時，如果
pi仍有任何正在執行的程序（如 所示ps -fu pi），則殺死它們——它們不應再重生。
