手邊一台ubuntu server升級,

login都會出現提示升級的訊息.看久了就只好升級看看會不會出事.

升級前驗明正身

orion@orion-B33E:~$ lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:    trusty
 

依提示執行sudo do-release-upgrade

一會兒就報錯....

The required dependency 'apt (>= 1.0.1ubuntu2.13)' is not installed.

------------------------------------------

搜尋一下才找到要先跑這兩個升級....

sudo apt update
sudo apt dist-upgrade

BUT, 這裡有個小插曲....

其中apt update跑到一半還會出現找不到public key的錯誤

There is no public key available for the following key IDs: 1397BC53640DB551

解方如下

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1397BC53640DB551

------------------------------------------

等到apt update/dist-upgrade都正常跑完後,

再跑sudo do-release-upgrade

就可以泡咖啡吃個販再來看結果了!!!!!
