update flow should handle `package is in a very bad inconsistent state;`

There are some cases in which our packages are in a bad state, and the update flow doesn't work. In particular, this command fails with

```
sudo dpkg --configure -a
```
```
dpkg: error processing package arduino-router (--configure):
 package is in a very bad inconsistent state; you should
 reinstall it before attempting configuration
Errors were encountered while processing:
 arduino-router
