currently my sda1 partition is set to Linux, but it is only using 15GB out of the total 20GB from the sda disk. I want to resize the sda1 partition without losing any data. Can anyone help me with this? Thank you.enter image description here

I have tried methods such as creating a new sda2 partition using the lvm file system from 5G that is available on the sda ​​disk but it also failed.
