Apparmor Init Gagal, Kode Keluar 123

Apparmor gagal menjalankan boot dan perintah mulai dengan hasil yang sama seperti di bawah ini

x@x-NICEPUTER:~$ systemctl --failed
  UNIT             LOAD   ACTIVE SUB    DESCRIPTION
● apparmor.service loaded failed failed LSB: AppArmor initialization

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

x@x-NICEPUTER:~$ systemctl status apparmor.service
● apparmor.service - LSB: AppArmor initialization
   Loaded: loaded (/etc/init.d/apparmor; bad; vendor preset: enabled)

Direktori apparmor/hardware/dan file graphics.dtidak ada di dalam /usr/share/ Jadi #include /usr/share/apparmor/hardware/graphics.dpada baris 26 dari /etc/apparmor.d/usr.bin.webbrowser-apppengembalian nol dan menyebabkan kegagalan.

Bagaimana saya bisa memperbaiki ini dengan benar atau setidaknya membuat solusi yang memungkinkan apparmor.serviceuntuk menginternalisasi tanpa kegagalan?

Tampaknya menjadi bug yang dilaporkan ( # 1554803 )

Ini dapat diselesaikan dengan menginstal apparmor-easyprof-ubuntuatau membuat folder dengan tangan.

sudo apt-get install apparmor-easyprof-ubuntu

Bagi saya, saya tidak dapat menginstal paket apa pun karena keduanya ifconfigdan network-managertidak dapat menemukan / memulai dongle wifi USB saya.

Jadi komentar @ xtrchessreal adalah yang bekerja untuk saya :

Dalam shell mode pemulihan, buat direktori berikut:

mkdir -p /usr/share/apparmor/hardware/graphics.d
mkdir -p /usr/share/apparmor/hardware/audio.d
mkdir -p /usr/share/apparmor/hardware/video.d

Lalu reboot

Dalam kasus saya, masalah muncul ketika saya menghapus paket snapd dengan apt-get remove snapd. Memeriksa syslog, tampaknya snapd uninstaller menghapus beberapa direktori tetapi bukan file konfigurasi apparmor yang merujuknya. Saya memangkas paket dengan apt-get purge snapddan me-restart apparmor tanpa kesalahan.
