I have 500 GB ssd. Used space shows 113 GB but free space only 50 GB

Question

I have ubuntu 22.04. I have 500 GB SSD. Used space shows 113 gb but free space only 25 gb. There should be atleast 250 GB of free space.

500 GB hard disk. (Available: 468 GB - Ubuntu: 25 GB - My data 113 gb - other 50 gb) = 280 GB. But only 25-50 GB free. Here is command df -h

apoorva@apoorva:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           1.6G  3.6M  1.6G   1% /run
/dev/sda2       468G  421G   25G  95% /
tmpfs           7.8G  313M  7.5G   4% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
efivarfs        160K   45K  111K  29% /sys/firmware/efi/efivars
/dev/sda1       511M  6.1M  505M   2% /boot/efi
tmpfs           1.6G   76K  1.6G   1% /run/user/128
tmpfs           1.6G  3.7M  1.6G   1% /run/user/1000

Try cleaning your system.

Open a terminal and run:

exec sudo -i
apt update
apt install --reinstall deborphan
apt autoremove
deborphan
apt --purge remove $(deborphan)
deborphan --libdevel
apt --purge remove $(deborphan --libdevel)
deborphan --find-config
dpkg --purge $(deborphan --find-config)
OLDCONF=$(dpkg -l|grep '^rc'|awk '{print $2}')
apt clean
apt purge $OLDCONF
rm -rf /home/*/.local/share/Trash/*/** &> /dev/null
rm -rf /root/.local/share/Trash/*/** &> /dev/null

Check if space has been freed with:

df -h
