virtual storage

http://derekmolloy.ie/resize-a-virtualbox-disk/

For the naming of the .vdi file:

I assume that you originally created a VM named "Ubuntu 18.04". Virtualbox suggests naming the related virtual disk "Ubuntu18.04.vdi". If you later do an in-place upgrade of Ubuntu (e.g. to 19.04), then these names will not change, creating an inconsistency between the VM name (and the disk name) and the contents.

This is answer for my second question (thanks), the firs one (how to enlarge storage) is still actual.

For the first part of your question actionparsnip has already provided a link in comment #1.

What is the problem with your system?
Are you running out of space with the current 20 GB?

what is the output of the commands

uname -a
lsb_release -crid
df -h | grep -v snap

Actually I have no problems, but every internal update consumes some space.
Last ubuntu base update increased used space by 3% and I anticipate future problems.
I have 2TB disk so I have plenty space I can dedicate for virtual machine, actually 20GB is just 1% of 2TB.
Is there utility cleaning /dev/sda1 ?

What is the output of the commands

uname -a
df -h | grep -v snap

You still have more than 6 GB free on the main file system in your Ubuntu VM.
Eventually you can free up some more space by deleting obsolete files, e.g. with the commands

sudo apt --purge autoremove
sudo apt autoclean

If you really want to allocate more space to it, then you have to follow the procedure in the link that actionparsnip gave in hist first comment.

It was good 1 and 1/2 year.
I enlarge the disk size to 40 GB using Virtual Media Manager
Virtual Size: 41.93 GB
Actual Size: 18.85
I expected to see more or less 35%, however actually I see:
/dev/sda1 20090472 15993444 3056700 84% /
What is wrong ?

If you reboot then run:

sudo fdisk -l

What is the output?

I enlarge the disk size to 40 GB using Virtual Media Manager
Virtual Size: 41.93 GB
Actual Size: 18.85

I assume that you only enlarged the virtual disk, but you did not expand the file system on it (That can be done e.g. by gparted.)

After the reboot, unmount the file system after stopping any services that access it. Then you can use fdisk to delete the partition and make a new partition at the larger size. Write the changes to the disk then fsck the file system and you can then resize the file system with resize2fs to make the file system the new size

Once again back to the old problem:
Is the possibility to expand virtual disk in virtual machine? or make the clone with larger virtual storage?
It is a critical problem for me, 96% is used, no update can be performed, I have planty free space in my HD.
Please help!

You have to distinguish between the site of the container file (*.vdi) and the partitions inside (/dev/sda1) and the file system on the partition. After increasing the size of the container you also have to enlarge the partition and then you have to modify the file system on the partition to use all space.
