    Good SNAP write up or how to

    I am looking for a good SNAP write up or how-to. Very new to Ubuntu and SNAP.

    Thank you

    man snap really is a good place to start. Whoever did the entry did a nice job and writes well. I'm quite impressed.
    regards

    snaps are new to everyone. They should be optional, but Canonical decided to force them and there have been lots of workflow breakage due to this choice.

    For 18.04 and earlier, it is still mostly possible to live snap free.

    snapcraft.io is the main website.
    There are a few different Ubuntu tutorials (those obnoxious step1, step2, step .... 15 wizard webpages. Google finds them easily.

    I haven't read the snapd manpage, because if it shows up on my systems, I purge it. When I can install VLC and have it work with all my other tools automatically on my desktop ,will read/play media files from anywhere on my network or on an external flash disk, then I'll know that the vlc snap is ready. They aren't there and don't seem to be headed in that direction.

    For now, sudo apt purge snapd is the easy answer. Don't know how well that will work for 19.10 and later. There have been statements made that Canonical will be only distributing some well-used packages as snaps going forward. If that is true, I'll miss Ubuntu.

    And when you've worked through the man page you can refer to the official snap documentation at Getting started which should answer any remaining questions that you may have.
    The Bug Squad needs your help.

    The snap link is what I needed, as you pointed out. I am reading the snap man today, so I am huddled down with my tea, lunch and Chrono Trigger OST playing.... LETS GO!!!

    Re: Good SNAP write up or how to

    Is there another version of Linux that does not use snaps? . I had to delete Firefox from Snap directory and reinstall in .mozilla to get flash to work. Tried to do a backup, but it could not access snap dir. So I will be looking elsewhere.

    all i saw was a reference document for a command. why that was in chapter 8 is unknown to me. i guess the web link is the next place to go.

    based on the contents list and not on reading straight through (because that much reading can take too much time so i want to optimize it an find the answers to my questions as directly as possible) this page is not the one to answer my main question.

    i went to the snapcraft.io website. i followed along "Learn how to snap an app in 30 minutes", selecting my language (one of them is missing) and OS (Windows is "coming soon" and BSD is not even there, at all. at least, Linux is there) but all i got were the steps to install some things. i get to learn what i should only need to do once?

    looks like i will need to learn to live with YAML. won't happen!

    my real questions are:

    why?

    what does snap give me (better) that other things do not give me (as good)?

    where is a document that can justify why we should use snap?
    What do you call someone who speaks three languages? Trilingual. Two languages? Bilingual. One language? American.

    Slackware was not in the list on the website.

    to me it gives the option to run the latest application on older version of the OS (the LTS). and a si understand you can also run an older version of the app on latest version of the OS. sometimes this is good to have especially with some games or if the features that changed you favourite app do not suite you.

    - can't crash the system
    - comes with its own package manager snapd
    - runs from a kind of read only virtual disk.
    - are updated automatically and only the modified parts of the virtual disk are sent.
    - you will have the newest version of the App, also if for deb files only an older version is supported,
    - full automatic and manual snapshot support and rollback to a previous version of that virtual disk
    - have a central storage for distribution, to avoid websites that distribute malware.

    Flatpack and Appimage are more vulnerable for attacks and both do not support snapshots. Flatpack only supports KDE, Gnome and FreeDesktop and their security is somewhat questionable. Appimage can be run on any distro by making the file executable, but then you have to add a link to the image in the menus or docks yourself. "Appimaged" should solve that, but than you have to install it like snapd. AppImage programs are not sandboxed.
