debconf: unable to initialize frontend: Dialog – Saat saya akan melakukan pengecakan update package-package pada sistem operasi Ubuntu 20.04 milik saya melalui perintah apt update, ada notifikasi error yang cukup mengganggu mata saya pada saat akhir proses update yaitu :
debconf: unable to initialize frontend: Dialog debconf: (No usable dialog-like program is installed, so the dialog based fro ntend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76. ) debconf: falling back to frontend: Readline
Untuk mengatasi hal error seperti ini saya hanya perlu menginstall package dialog nya saja melalui perintah.
$ sudo apt install dialog -y

Selanjutnya saat menjalankan perintah apt update pun sudah tidak ada lagi notif error seperti diatas, selamat mencoba.
