#wsl #debian #bookworm #bullseye

Aku nok pakai php 8.2, jadi kena upgrade bullseye ke bookworm. step untuk upgrade adalah sebagaimana di bawah:-

root@local:/# lsb_release -a

Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)

root@local:/# uname -a
Linux 5.15.90.1-microsoft-standard-WSL2 #1 SMP Fri Jan 27 02:56:13 UTC 2023 x86_64 GNU/Linux

root@local:/# cat /etc/apt/source.list

deb http://deb.debian.org/debian bullseye main
deb http://deb.debian.org/debian bullseye-updates main
deb http://security.debian.org/debian-security bullseye-security main
deb http://ftp.debian.org/debian bullseye-backports main

Change source.list from bullseye to bookworm with vi/nano/pico

deb http://deb.debian.org/debian bookworm main

deb http://security.debian.org/debian-security bookworm-security main
deb http://ftp.debian.org/debian bookworm-backports main

root@local:/# apt update

root@local:/# apt upgrade --without-new-pkgs

Perform full-upgrade will replace php 8.1 to new php 8.2 ( if previous wsl2 installed with linux bullseye has php 8.1 )

root@local:/# apt full-upgrade

After that, validate php version
