Я намагався, sudo apt-get update && sudo apt-get upgradeале ефекту немає, та сама проблема.

Я щойно встановив Ubuntu. vim працює, але ABCD друкується при натисканні клавіш зі стрілками.

Хорхе Кастро запропонував: "Ви можете використовувати дзеркало деб, щоб автоматично було вибрано найкраще дзеркало.

apt-get now supports a 'mirror' method that will automatically select a good mirror based on your location. Putting:

deb mirror://mirrors.ubuntu.com/mirrors.txt precise main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt precise-updates main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt precise-backports main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt precise-security main restricted universe multiverse

ВІН ПРАЦЮЄ МНЕ! Я додав вищевказані рядки в

/etc/apt/sources.list

вгорі, а потім я

sudo apt-get update

і потім

sudo apt-get install vim

РОБОТИ!

З огляду на http://pk.archive.ubuntu.com/ubuntu/ здається, що дзеркало, яке ви використовуєте, застаріло. Спробуйте змінити дзеркало на щось інше, щоб потім виправити помилку:

• Як я можу погодитися використовувати дзеркало поруч зі мною або вибрати більш швидке дзеркало?
• Як у командному рядку вибрати найшвидше дзеркало?

Вам потрібно додати репорта deb-src до свого source.list.

sudo nano /etc/apt/sources.list

Видаліть #з рядка , яка починається з #deb-srcпотім Ctrl+ o, Enter, Ctrl+ xдля збереження і виходу з нано.

sudo apt-get update
sudo install vim

І буде встановлено vim.
