uWSGI

Doesn't seem to work with PHP 8.2 and Ubuntu 20.04

With Ubuntu 20.04, ondrej ppa and PHP 8.2 installed, the following dependencies are wrongly installed: php7.4-cli php7.4-common php7.4-json php7.4-opcache php7.4-phpdbg php7.4-readline

!!! UNABLE to load uWSGI plugin: libphp7.so: cannot open shared object file: No such file or directory !!!

# better use --plugin option instead of the following workaround sudo ln -s /usr/lib/libphp8.so /usr/lib/libphp7.so
