Reset Google Colaboratory VM

Question

From https://research.google.com/colaboratory/faq.html we can see that:

The code runs in a virtual machine dedicated to your account. Virtual machines are processed in standby mode for a while and have the maximum service life provided by the system.

Installing additional packages, I kind of messed up the virtual machine in which I am now (playing with /etc/apt/sources.list ... for example).

Is there a way to make the machine reset or recycle? If not, do we know the life time or downtime before being recycled?

thanks

Answer 1

VM recycle after 90 m of inactivity.

You need to close any open browser tabs, since the connection to the virtual machine is considered active.
