# Light upgrade

Always begin with creating/attaching screen/tmux
```bash
tmux a
tmux
sudo su
```


On metered Internet connection, light upgrade scenario

Do not do update, as it will update minor version for repos, which will force bigger update
```bash
#! DO NOT DO IT (unless want to update minor version)

apt update
```
This will automatically lead to minor version upgrade (version variable will be substituted)
