In that lesson, there is a mix among apt, apt-get and apt-cache that is a mess up. You don't teach which is the difference, you just write that some command are with apt, and some other with apt-get

Reading man apt page:
apt provides a high-level commandline interface for the package management system. It is intended as an end user interface and enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get(8) and apt-cache(8).

Why don't you write this?

Appart of this, some commands are wrong:

  • sudo apt --purge remove [package] -> not exists, should be sudo apt-get --purge remove [package] or sudo apt purge [package]
  • sudo apt dist-upgrade -> not exists, should be sudo apt-get dist-upgrade or sudo apt full-update

This is supposed a serious Linux course, but any beginner blog explain better the apt commad than this expensive course

Please, review this lesson

    Hi @faramayo,

    I went through the material and I didn't find notorious issues;

    In that lesson, there is a mix among apt, apt-get and apt-cache that is a mess up. You don't teach >which is the difference, you just write that some command are with apt, and some other with apt-get

    Oh, I see explanations in subsections What Is APT?, apt, apt-get, apt-cache, etc. and Queries.

    Also, you should be able to search for basic stuff like that and do 'man' and the commands you want to find information about.

    sudo apt --purge remove [package] -> not exists, should be sudo apt-get --purge remove [package] >or sudo apt purge [package]

    Oh, well, that forn is working on my system:

    luis@ubuntuserver:~$ sudo apt --purge remove apt-file
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    The following packages were automatically installed and are no longer required:
    libapt-pkg-perl libexporter-tiny-perl liblist-moreutils-perl liblist-moreutils-xs-perl
    libregexp-assemble-perl
    Use 'sudo apt autoremove' to remove them.
    The following packages will be REMOVED:
    apt-file*
    0 upgraded, 0 newly installed, 1 to remove and 6 not upgraded.
    After this operation, 92,2 kB disk space will be freed.
    Do you want to continue? [Y/n]

    And purge alone:

    luis@ubuntuserver:~$ sudo apt purge apt-file
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    The following packages were automatically installed and are no longer required:
    libapt-pkg-perl libexporter-tiny-perl liblist-moreutils-perl liblist-moreutils-xs-perl
    libregexp-assemble-perl
    Use 'sudo apt autoremove' to remove them.
    The following packages will be REMOVED:
    apt-file*
    0 upgraded, 0 newly installed, 1 to remove and 6 not upgraded.
    After this operation, 92,2 kB disk space will be freed.
    Do you want to continue? [Y/n]

    What version are you running?

    sudo apt dist-upgrade -> not exists, should be sudo apt-get dist-upgrade or sudo apt full-update

    That's also working on my system running Ubuntu 22.04.3 LTS:

    luis@ubuntuserver:~$ sudo apt dist-upgrade
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    Calculating upgrade... Done
    The following NEW packages will be installed:
    linux-headers-6.5.0-14-generic linux-hwe-6.5-headers-6.5.0-14 linux-image-6.5.0-14-generic
    linux-modules-6.5.0-14-generic linux-modules-extra-6.5.0-14-generic
    The following packages have been kept back:
    dnsmasq-base gjs libgjs0g
    The following packages will be upgraded:
    linux-generic-hwe-22.04 linux-headers-generic-hwe-22.04 linux-image-generic-hwe-22.04
    3 upgraded, 5 newly installed, 0 to remove and 3 not upgraded.
    3 standard LTS security updates
    Need to get 133 MB of archives.
    After this operation, 721 MB of additional disk space will be used.
    Do you want to continue? [Y/n]

    Regards,
    Luis.

    Hi

    Yes, you are right, these commands works. Search for this command in man, as you say, and try to find dist-upgrade in apt man. Not exists. The command workis just for compatibility, but apt came for replace apt-get and apt-cache, thus I think that a leading course should use up-to-date commands, that's all.

    apt is not only a replacement for apt-get and apt-cache. There are low level commands that work with apt-get differently than apt. This is also distribution dependent. Note the comments you will find about apt-get being for use with scripts. You cannot "fix" all this discussion as only experience will tell you the quirks on different distributions and different versions within them.
