云芯一号试用 - 升级ubuntu 18.04到20.04

默认云芯一号是ubuntu18.04的系统,都2020了,系统也可以升级一下啦。
首先,还是把当前版本升级到最新的

sudo apt udpate
sudo apt upgrade

升级非常方便,安装update-manager-core

sudo apt install update-manager-core
sudo do-release-upgrade -m server -d

将会看到如下log:

Checking package manager

Continue running under SSH? 

This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. 

If you continue, an additional ssh daemon will be started at port 
'1022'. 
Do you want to continue? 

Continue [yN] y
Starting additional sshd 

To make recovery in case of failure easier, an additional sshd will be started on port '1022'. If anything goes wrong with the running ssh you can still connect to the additional one. 
If you run a firewall, you may need to temporarily open this port. As this is potentially dangerous it's not done automatically. You can open the port with e.g.: 
'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT'

Updating repository information

No valid mirror found 

While scanning your repository information no mirror entry for the 
upgrade was found. This can happen if you run an internal mirror or 
if the mirror information is out of date. 

Do you want to rewrite your 'sources.list' file anyway? If you choose 
'Yes' here it will update all 'bionic' to 'focal' entries. 
If you select 'No' the upgrade will cancel. 

Continue [yN] y

Third party sources disabled 

Some third party entries in your sources.list were disabled. You can 
re-enable them after the upgrade with the 'software-properties' tool 
or your package manager. 

To continue please press [ENTER]
