I'm getting: [ERROR] Exception occured: ISPConfigOSException -> Installing packages failed. (/ispconfig.ai.php:15) It failed after attempting to install Installing packages: software-properties-common, dnsutils, resolvconf, clamav, clamav-daemon, clamav-docs, zip, unzip, bzip2, xz-utils, lzip, rar, arj, nomarch, lzop, cabextract, apt-listchanges, libnet-ldap-perl, libauthen-sasl-perl, daemon, libio-string-perl, libio-socket-ssl-perl, libnet-ident-perl, libn et-dns-perl, libdbd-mysql-perl, bind9, spamassassin, rspamd, redis-server, postgrey, p7zip, p7zip-full, unrar-free, lrzip I suspect this is because rar is not available on Debian 11/arm64. I had that problem with a manual installation on Debian 10. I also had an issue with rspamd but there is a directive to not tinstall. Hence I'm looking for a way to modify the script to not install rar or anything else that may cause a hiccup. I've had a look in the /tmp/ispconfig-ai directory but can't find the apt install commands. What do you suggest?
