- start the upgrade

apt-get updateapt-get dist-upgrade

Because the wheezy 7.8 version of my machine was upgraded from Squeeze 6. Daily life, work, development and so on use a lot of software. So take the upgrade package down near the 2G.

Long download ...

During the upgrade, you will be asked if you need to disable root SSH password, keyboard mapping, server configuration (Apache, PHP, Nginx, MySQL), etc., SYSCTL,PPTPD configuration, Certdata, etc., reset the language environment, Choose whether to keep or use the latest configuration on demand.

Vim has been upgraded from 73 to 74. So if there is a custom configuration or a soft link, then the relevant configuration and soft links also need to be modified.

After the upgrade is complete.
