Hello, i am using debian 11 with php 5.6 and php 7.4 versions. I would like to remove some packages for better orientation. I am using standard php apps - phpbb system, phpmyadmin and ispconfig with webmail, that is all. Only php website. I have installed and some package was preinstalled when i buy my vps from vps provider. List my installed package is here. For example there is a lot of times for python 3, not sure if i can remove it, a have disable it in ispconfig for domains. For example i will removed ruby because i dont need it. Is safety to remove for example python when i am using ispconfig? If somebody will have idea about any unnecessary which i can remove from this list, let me know please, thanks In Attached File you can see list of all installed packages Code:

I do not know if ISPConfig uses python, but may OS utilities do use python. So removing python completely breaks the system. Many packages can be removed by listing them all in one line. Advanced methods involve scripting collecting the names of packages and adding that collection to the command line. Code: apt remove ruby-minitest ruby-net-telnet ruby-power-assert and so on
Thank you. I tried to remove ruby via command Code: apt remove ruby-minitest ruby-net-telnet ruby-power-assert ruby-rack ruby-rubygems ruby-test-unit ruby-xmlrpc ruby2.1 ruby2.7 ruby but in remove list is wrote Code: The following packages will be REMOVED: libapache2-mod-passenger libruby libruby2.7 passenger rake ruby ruby-minitest ruby-net-telnet ruby-power-assert ruby-rack ruby-rubygems ruby-test-unit ruby-xmlrpc ruby2.1 ruby2.7 vim-nox Not sure why there is package libapache2-mod-passenger or passenger rake. Maybe because icnlude ruby? I guess thats not safety to remove this package. I tried to run Code: dpkg -l | grep ruby and get Code: root@xy:~# dpkg -l | grep ruby ii libruby 1:2.7+2 all Libraries necessary to run Ruby ii libruby2.1:amd64 2.1.5-2+deb8u9 amd64 Libraries necessary to run Ruby 2.1 ii libruby2.7:amd64 2.7.4-1 amd64 Libraries necessary to run Ruby 2.7 ii rake 13.0.3-1 all ruby make-like utility ii ruby 1:2.7+2 amd64 Interpreter of object-oriented scripting language Ruby (default version) ii ruby-minitest 5.13.0-1 all Ruby test tools supporting TDD, BDD, mocking, and benchmarking ii ruby-net-telnet 0.1.1-2 all telnet client library ii ruby-power-assert 1.1.7-2 all library showing values of variables and method calls in an expression ii ruby-rack 2.1.4-3 all modular Ruby webserver interface ii ruby-rubygems 3.2.5-2 all Package management framework for Ruby ii ruby-test-unit 3.3.9-1 all unit testing framework for Ruby ii ruby-xmlrpc 0.3.0-2 all XMLRPC library for Ruby ii ruby2.1 2.1.5-2+deb8u9 amd64 Interpreter of object-oriented scripting language Ruby ii ruby2.7 2.7.4-1 amd64 Interpreter of object-oriented scripting language Ruby ii rubygems-integration 1.18 all integration of Debian Ruby packages with Rubygems Can not see there about libapache2-mod-passenger so i guess this is not include ruby
If apt wants to remove libapache2-mod-passenger then likely some of those ruby packages depends on it (that is, when that ruby-something package was installed it installed libapache2-mod-passenger as a dependency. You can read about dependences in Debian and APT documentation). Now that ruby-something package is removed, and libapache2-mod-passenger is removed also. If something else still depended on that package, it would not get removed. So removing libapache2-mod-passenger should be safe. Although I do not undestand this desire to remove packages. It is possible to do but requires knowledge of the system and on how APT works. So maybe forget about this removing?
Thank you, Taleman. My only goal is that i would like to remove packages which i dont need for running of my VPS. Because when i listed all installed package, I get a lot of them and i would like to use just packages i really use. But you are right, maybe will be better forget about this removing.
