Я новичок в ОС Ubuntu. Я пытаюсь обновить версию с 14.04 до 16.04. Но не удалось обновить последнюю версию.
Ниже я получил сообщение при обновлении, поэтому я внес изменения в sources.list, используя http://repogen.simplylinux.ch.
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
Но файл sources.list не обновляется должным образом. Файл показывает как:
###### Ubuntu Main Repos
deb http://in.archive.ubuntu.com/ubuntu/ xenial main
deb-src http://in.archive.ubuntu.com/ubuntu/ xenial main
###### Ubuntu Update Repos
deb http://in.archive.ubuntu.com/ubuntu/ xenial-updates main
deb-src http://in.archive.ubuntu.com/ubuntu/ xenial-updates main
:wq
:wq!
:wq
И мой оригинальный файл sources.list был таким:
