Should I increase my partition size when the volume “Filesystem Root” has only few disk space remaining? [duplicate]

  • 772

My question differs from The volume "Filesystem Root" has only 533.9 MB disk space remaining, for mine is specific about managing disk space on multiboot devices

From time to time, the system shows this warning message:

I have a dual-boot with Windows 10 and Ubuntu 16.04. Here's what fdisk shows:

    Yes, you should definitely increase the size of root from 39GB. Suggest you

    A) Make two backups of each partition with data

    B) Do 

    sudo apt-get autoclean && sudo apt-get autoremove && sudo apt-get clean

    C) Use gparted after booting from a Live USB and adjust partition sizes to increase the space available to root.
