当我尝试在ec2上连接ubuntu时,出现以下消息
New release 'natty' available.
Run 'do-release-upgrade' to upgrade to it.
但是当我尝试运行此命令时,我收到以下消息:
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?
它说:“不建议通过ssh进行升级”。如果我不能在ssh上运行它,还有什么其他方法可以更新我的Ubuntu。另外,我真的不想丢失有关ec2的数据。
