Cara Memperbaiki Clearsigned file isn't valid, got 'NOSPLIT' Berdasarkan Pengalaman Pribadi

MATIKAN mirror.idcloudhost dengan cari dulu filenya:

grep -R "idcloudhost" /etc/apt/

Biasanya ketemu di:

/etc/apt/sources.list.d/*.list

Contoh:

 root@geralnb# grep -R "idcloudhost" /etc/apt/
/etc/apt/sources.list.d/ubuntu.sources:#URIs: http://mirror.idcloudhost.com/ubuntu

Nonaktifkan (AMAN) dengan command

mkdir -p /root/apt-backup
mv /etc/apt/sources.list.d/*idcloudhost* /root/apt-backup/ 2>/dev/null 

Disable sources.list

mv /etc/apt/sources.list /etc/apt/sources.list.disabled

Edit ubuntu.sources

nano /etc/apt/sources.list.d/ubuntu.sources

Pastikan isinya seperti ini (boleh full replace):

Types: deb
URIs: http://archive.ubuntu.com/ubuntu
Suites: noble noble-updates noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Types: deb
URIs: http://security.ubuntu.com/ubuntu
Suites: noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Save & exit.

Bersih dan Update

apt clean
rm -rf /var/lib/apt/lists/*
apt update
apt upgrade -y

Penyebab 1

mirror.idcloudhost MASIH AKTIF. Walaupun sudah edit /etc/apt/sources.list, APT masih membaca repo lain, yaitu:

http://mirror.idcloudhost.com/ubuntu

Itu BUKAN dari sources.list, tapi dari file lain. 

Penyebab 2

DUPLIKASI REPO (Ubuntu 22.04+ pakai format .sources). Error warning ini kuncinya: 

configured multiple times in:
- /etc/apt/sources.list
- /etc/apt/sources.list.d/ubuntu.sources 

Artinya masih pakai sources.list (lama) dan Ubuntu Noble juga pakai ubuntu.sources (format baru)
➡️ Jadi repo dobel + bentrok
