Masalahnya
Tidak dapat memulai layanan polkitd, yang selanjutnya memengaruhi layanan lain juga.

Masalah ini disebabkan oleh izin yang salah untuk file dan direktori terkait polkit. Polkit digunakan untuk mengontrol hak istimewa seluruh sistem. Ini menyediakan cara terorganisir untuk proses non-hak istimewa untuk berkomunikasi dengan yang istimewa. Berbeda dengan sistem seperti sudo, ini tidak memberikan izin root ke seluruh proses, melainkan memungkinkan tingkat kontrol kebijakan sistem terpusat yang lebih baik.
1. Pastikan user dan group polkitd ada, jika tidak coba install ulang RPM :
# getent passwd polkitd polkitd:x:999:997:User for polkitd:/:/sbin/nologin # getent group polkitd polkitd:x:997:
2. Setel ulang izin dan kepemilikan pengguna/grup untuk semua file yang disediakan oleh paket polkit dan polkit-pkla-compat:
# rpm -Va polkit # rpm --setugids polkit polkit-pkla-compat # rpm --setperms polkit polkit-pkla-compat
3. Periksa lagi jika masalah sedang dihadapi lagi. Jika demikian, Coba instal ulang/perbarui RPM ke versi terbaru:
# yum reinstall polkit ...

4. Verifikasi status layanan dbus, jika menonaktifkan restart layanan:
# systemctl status dbus

5. Jalankan layanan polkitd dengan opsi debug:
# /usr/lib/polkit-1/polkitd Error switcing to user polkitd: Error changing to home directory /: Permission denied <<< Exiting with code 1
Kesalahan yang terlihat adalah karena pengguna polkitd tidak dapat berpindah direktori home. Verifikasi direktori home:
# cat /etc/passwd |grep polkitd polkitd:x:999:998:User for polkitd:/:/sbin/nologin
Dapat melihat direktori home adalah "/", verifikasi izin dari /tmp, /home, /etc, /var, /bin, /run dan /

# ls -ld / drwx------. 17 root root 4096 Jan 2 20:17 /
6. Izin yang terlihat dari "/" adalah 700 bukannya 555, perbaiki dan mulai ulang layanan:
# ls -ld / drwx------. 17 root root 4096 Jan 2 20:17 /
# chmod 555 /
# ls -ld dr-xr-xr-x. 17 root root 4096 Jan 2 20:17 .
