# Debian 10

# SECURITY
deb http://security.debian.org/ buster/updates main

# Main
deb http://kartolo.sby.datautama.net.id/debian/ buster main

# NON FREE
deb http://httpredir.debian.org/debian buster main contrib non-free

# BACKPORT
deb http://ftp.debian.org/debian buster-backports main

Note on error when running apt-get update:
E: Release file for http://kambing.ui.ac.id/debian/dists/buster/InRelease is expired (invalid since 265d 4h 18min 17s). Updates for this repository will not be applied.
use other sources e.q change "deb http://kambing.ui.ac.id/debian/ buster main contrib
" to "deb http://mirrors.kernel.org/debian buster main contrib"
If you used oracle mysql or oracle virtualbox, you need to modify to "buster" these files:

defender locking bignox virtual disk

windows defender sometimes open file in background process, to scan for malicious code. If defender (or other antivirus) open bignox virtual disk it will lock it and cause your emulator crash. You need to exclude virtual disk that used by bignox. Here are the steps you need to do:

1. Open your windows defender (or your antivirus)
2. Go to setting "Virus & thread protection settings"
3. in "Exclusions" click "Add or remove exclusions"
4. Click "Add an exclusion" and choose "File type"
5. in "Enter extension" box type "vmdk"
6. repeat step 4 for file type "vbox" and "vdi"

You may want to increase your emulator by excluding these files:

1. C:\Program Files (x86)\Bignox\BigNoxVM\RT\NoxVMSVC.exe
2. C:\Program Files (x86)\Nox\bin\Nox.exe
