Auto partition /home /var /tmp separated on 150Gb no space for finalise installation

What have you tried:
install with netinstall
auto partition lvm crypted with options /home /var /tmp separated on disk sata-sas 146Gb

partition /home 117gb
partition /root 13gb
partition /swap 7gb
partition /tmp 2gb
partition /var 4.7gb

i try auto partition all-in-one and i come back to you
What is the error:
installa
tion stopped because no space for ~2600 packets
what device is this on:
dell poweredge 2950 bi-xeon ram 64gb

/ with only 13 GB is very tight for a full Linux install with a graphical environment and extras.

/var at 4.7 GB is also too small for large package extraction and logs.

Some distros (especially Debian/Red Hat-based) need 10-15 GB for just /var during installation of many packages.
