Debian Stretch: Distribution Upgrade to Debian Buster (10)

Prepare apt /etc/apt/sources.list, change stretch to buster
my apt source list:

# Debian 10

deb buster/updates main

# Main
deb buster main

deb buster main contrib non-free

deb buster-backports main

Note on error when running apt-get update:
E: Release file for is expired (invalid since 265d 4h 18min 17s). Updates for this repository will not be applied.
use other sources e.q change "deb buster main contrib
" to "deb buster main contrib"

If you used oracle mysql or oracle virtualbox, you need to modify to "buster" these files:

Restart your computer

# cat /etc/debian_version
# uname -an
Linux fujitsu01 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5 (2019-06-19) x86_64 GNU/Linux

You can clean and remove unused temporary to make your system "tidy"
# apt-get autoclean && apt-get autoremove

By default, Debian 10 use kernel 4.19, you mau remove your old kernel.
# apt-get remove linux-image-4.9.0-9-amd64

DO NOT DELETE linux-image-4.19!


Intel(R) Atom(TM) CPU N455   @ 1.66GHz (Fujitsu) takes 3 hours to completed. Don't worry, It's much faster then windows 10 update or windows update clean up LOL.
