Installation stuck at "Creating ext4 file system"

Question

I would like to ask for assistance in the following installation problem.

Here I choose the option Erase disk and install Ubuntu and next Continue on Writing the changes to the disk? dialog.

The problem is that when the installation is in that status, there is no progress and the installation cannot be completed.

If there is another option I should follow, please let me know. I remain at your disposal for more details.

I would like to edit the question, adding two more photos to ask for more instructions.

In this photo is the initial screen when I run GParted.

When I click on Device, and then Create Partition table, I have the following message and I cannot continue.

Could you advice how much should be the size of the partitions? My disk capacity is 300 GB and the memory is 2 GB. When I try to create the new partitions I have the following error:

Thank you in advance,
Nikos

Answer 1

Boot from Ubuntu installation media.
Select 'Try Ubuntu without installing'.

Open GParted -> press the Windows key and type GParted.
Open GParted and delete all partitions you find on the disk.

Create a new partition - format it with ext4 - a size that fits your needs.
Create a new partition - format it with swap - a size matching the RAM.

On the desktop click Install Ubuntu, when asked choose Something else.
Select the ext4 partition you had created with GParted for Ubuntu before.
Select / as mount point and ext4 file system as format - start the installation.

Update addressing your comment that you receive errors and cannot create partitions :

Open GParted - click on Ignore.
Click on Device on the top menu.
Now click on Create Partition Table.
Select gpt when you have UEFI BIOS.
Select msdos when you have legacy BIOS.
Now you can create new partitions on the disk.

Update addressing your comment that you receive an error partition is currently active :

Screenshot shows that the swap partition is mounted.
Right-click the partition sda5 and click on Swapoff.
Right-click the partition sda2 and click Unmount.
In case it is not possible from Ubuntu media,
do it with the original GParted Live media.

Answer 2

Make USB bootable and open ubuntu in try ubuntu mode. Open -> Gparted select the partition in which you want to install ubuntu. if it is already unallocated right click on that partition to create a new partion.

-> select partition type as ext4
-> create partition

Now your problem where you were stuck.

-> while installing Ubuntu
    -> select something else
    -> select the partition in which you want to install Ubuntu double click it
    -> select mount point as /

and follow rest installation steps its done
