8.0 is probably a better option for now.

The root cause is explained here:

https://www.inex.ie/pipermail/ixpmanager/2021-November/003340.html

To fix it:

1. remove the package aliases for the packages most likely to cause the 
problems:

# dpkg -r php-ds php-igbinary php-memcache php-memcached php-msgpack 
php-rrd php-yaml

2. get a list of php8.1 packages:

# dpkg -l | grep php8.1

and carefully deinstall them.

3. install the correct list of IXP Manager dependencies:

# apt install -qy php8.0 php8.0-intl php8.0-rrd \
php8.0-cgi php8.0-cli php8.0-snmp php8.0-curl \
php8.0-memcached libapache2-mod-php8.0 php8.0-mbstring \
php8.0-xml php8.0-gd php8.0-bcmath php8.0-memcache \
php8.0-zip php8.0-yaml php8.0-ds php8.0-mysql \
libapache2-mod-php8.0 composer apache2 memcached \
mysql-server mysql-client snmp curl bgpq3 git unzip \
libnetaddr-ip-perl libconfig-general-perl libconfig-general-perl \
libnetaddr-ip-perl librrds-perl mrtg rrdtool
