After spending another day, finally I have solved the issue.

So for those who want to benefit it, here is the step by step updating Xdebug for Local by Flywheel on Debian systems.

  1. Download the version of Xdebug from here in my case it was 3.0.4 so I have changed the tgz’s filename to 3.0.4
  2. Unpack the tarball with tar -xzf xdebug-3.0.4.tgz
  3. Change directory with cd xdebug-3.0.4
  4. Run Local by Flywheel’s phpize binary. In my case it was located here sudo ~/.config/Local/lightning-services/php-8.0.0+3/bin/linux/bin/phpize this may change according to your setup.
  5. Edit Local by Flywheel’s php-config in my case it was located here ~/.config/Local/lightning-services/php-8.0.0+3/bin/linux/bin/php-config. Replace these values
SED="/usr/bin/sed"
prefix="~/.config/Local/lightning-services/php-8.0.0+3/bin/linux/"
datarootdir="/usr/share"
extension_dir='~/.config/Local/lightning-services/php-8.0.0+3/bin/linux/lib/php/extensions/no-debug-non-zts-20200930'
ini_path="/etc/php/8.0/cli"

Save the file
Note: Make sure you have installed php8.0 in your local machine
6. Run command sudo ./configure --with-php-config=~/.config/Local/lightning-services/php-8.0.0+3/bin/linux/bin/php-config --enable-xdebug
7. sudo make && sudo make install
8. Now you should be able to see xdebug 3.0.4 installed from the php -i or phpinfo page of your installation.
9. Add xdebug.mode=debug to your php.ini.hbs file
10. Restart your website. Now you should be able to debug with 3.0.4 and this will solve the Xdebug 3.0.0’s 502 bug.
