Increase size of root partition after installing Ubuntu in Windows

rated 0 times [ 9] [ 0] / answers: 1 / hits: 22674 / 2 Years ago, sat, november 20, 2021, 5:26:48

Every time update manager prompts an update I get a message saying that there is not enough space available, however the partition with Ubuntu installed has over 10 GB of free space available.

I'm lost as to what needs to be done.

df -h returns:

Filesystem            Size  Used Avail Use%   Mounted on

/dev/loop0            5.6G  5.1G  237M  96% /

udev                  2.0G  4.0K  2.0G   1% /dev

tmpfs                 786M  792K  786M   1% /run

none                  5.0M     0  5.0M   0% /run/lock

none                  2.0G  332K  2.0G   1% /run/shm

/dev/sda6              20G  6.7G   13G  34% /host

/dev/sda5             175G  120G   56G  69% /media/DATA

It would be great if someone could help me out on how to solve this problem. I'm a newbie to Ubuntu.

Your / partition is full, 96% used, 237Mb free space. That is where your packages will be downloaded and installed.

From what I see this is a Wubi install. You can resize your Wubi partition using the method described on this post

How to increase the partition size of Ubuntu installed under Windows?

Basically you need to follow these to the letter:

Get root privileges

sudo -i

Check how much space you have in your Windows disk

df -h /host

Create a new virtual disk bigger than the one you have at the moment, lets say 10GB

(change the count= parameter as appropriate)
```
cd /host/ubuntu/disks

dd if=/dev/zero of=new.disk bs=1MB count=10000
```

Format the new disk

mkfs.ext4 -F new.disk

Mount and copy files to new virtual disk



mkdir -p /media/newdisk

mount -o loop new.disk /media/newdisk

rsync -av --exclude '/sys/*' --exclude '/proc/*' --exclude '/host/*' --exclude '/mnt/*' --exclude '/media/*/*' --exclude '/tmp/*' --exclude '/home/*/.gvfs' --exclude '/root/.gvfs' --exclude '/var/lib/lightdm/.gvfs' / /media/newdisk

umount /media/newdisk

exit

Reboot into Windows and rename the file ubuntudisks oot.disk to ubuntudisksold_root.disk.

Rename the file ubuntudisks ew.disk to ubuntudisks oot.disk.

Reboot back into Ubuntu and check if everything is working. When you are 100% sure that everything is on the right places you can login to Windows and delete the file old_root.disk to get those 5Gb back.
