Ubuntu partition
Note
If your hard drive size is less than 60GB, just ignore partitioning and use entire drive to install Ubuntu.
EFI System Partition
This partition is mandatory if your laptop/computer is booting using UEFI instead of Legacy. It is usually allocated 200 MB of space.
Mount point: Not required
Type: efi
Size: 200 MB
Swap Partition
This partition is used when the RAM is insufficient to run applications. Its function is similar to paging in Windows. You should allocate at least as much space for this partition as your RAM.
Mount point: Not required
Type: swap
Size: 8 GB (if RAM is 8 GB)
Root Partition
This is a mandatory partition. It will be mounted at
/. I usually allocate 30 GB to it, but you can assign more if you wish.Mount point: /
Type: ext4
Size: 30 GB
Home Partition
This partition stores personal files. Each user will have a folder here. I create a separate partition for it so that if Ubuntu is reinstalled or upgraded, all user files will be preserved.
Mount point: /home
Type: ext4
Size: 100 GB (can be more if needed for extensive use)
Data Partition
This partition is used to store data shared with Windows. That’s why it has the NTFS file system. Later, if I plan to return to Windows, I won’t format or delete this partition. Since it uses NTFS, Windows can easily read it.
Mount point: Not required
Type: ntfs
Size: The remaining space on the hard drive

Solution: Check for Software Updates
what is the “~/.local” and can I delete it?
~/.local - or more precisely, ~/.local/share - ``is where XDG-compliant programs store user data (e.g., fonts, mail messages) according to the XDG Base Directory specification.
The ~/.local folder also contains share/Trash, which is your trash bin. Everything you put in there of course takes up space. I assume this is the most likely cause of disk usage.
Check how much space it takes up with:
du -hs ~/.local/share/Trash
If you don’t need to keep items in the trash, empty it through your file manager or just delete everything in share/Trash with:
rm -rf ~/.local/share/Trash
Commands

sudo rm -r -f /path/
