Setelah instalasi baru Ubuntu 16.04, saya memiliki paket yang rusak dan tidak dapat menginstal sebagian besar aplikasi. Saya mencoba dari Synaptic "Perbaiki paket yang rusak" tetapi tidak berfungsi. Contoh;

sudo apt-get install steam

16.04 baru dan semua paket belum siap digunakan di semua server. Menggunakan Server Utama untuk mengunduh paket memecahkan masalah saya.

1. Setelan Sistem
2. Perangkat Lunak &Pembaruan
3. Pilih “Server Utama” dari bagian “Unduh dari”

Terkait:Banyak kesalahan otentikasi PAM pada log yang menargetkan server surat. Bagaimana cara menghentikannya?
