Answer 1

[Игорь Махов]

[Василий]

В моем случае это решение не подходит так как это виртуальная машина созданная не мной и не факт что ее можно обновить.

sudo mv /etc/apt/sources.list /etc/apt/sources.list-bak

sudo nano /etc/apt/sources.list
Shift-Ins, Ctrl-W
sudo apt update
Но это помогло бы, если бы обновления все еще существовали.
