Linux Crash Course - The apt Command

- เผยแพร่เมื่อ 10 ก.พ. 2021
- In my "Linux Crash Course" series, I go over a very specific command to give you an overview of how it works. In today's episode, I go over the basics of the apt command, which is the official package manager for Debian, Ubuntu, and others.

Probably the best apt tutorial I've seen so far
Good lesson.don’t underestimate how less people know. Please keep on over explaining. I did not knowcapital is default. It takes 5 secs to explain. Tmux enables to run multiple terminal command windows. Thank you.
Thank you, Jay. I love APT. As soon as I started to use APT it had me learning the terminal, bash, reading man pages etc etc. And I spent quite a while on Debian itself simply out of love for APT.
Already gave the video a like before I even finish watching because I know it’ll be great! Was looking to learn more about this. I’ve been using Centos for school and my love for Linux is ever growing
Excellent content. The t-shirt is brilliant.
Thanks Jay :-D it's nice to follow along as you teach :-D you make learning Linux fun. Thanks for catering for beginners.
Add "apt show " to show more info about a package and that would cover all apt commands that I normally use.
Great instructional video. I generally use package managers, such as Synaptic or distro-specific PMs, but it's cool to know what is actually going on behind the GUI. I sometimes use the terminal as well. I didn't know about using search in the terminal. Excellent tutorial.
What a coincidence! I started using Linode due to one of your earlier videos (and I'm glad I did.
Appreciate these essential videos!
Really enlightening. Many thanks.
Great explanations! Many thanks
This is fantastic! Thank you very much.
Thank you man i pretty much knew the most of that but some stuff was rly usefull for example i didnt know it was possible to install multiple packages at once or that package name search where you just tipe a keyword in that was veeeeeeeery usefull thanks alot man
Spot on explanations.
Jay's new book on Ubuntu Server is really good and helps me understand much more about this system
this is going to be my apt manual
thank you 🙏
I dont mean to be offtopic but does any of you know of a way to log back into an Instagram account??
I stupidly forgot my password. I would love any tips you can offer me
I love it!
Thanks for the video
Great video!
Well explained, I thought I knew all I needed to know about apt, but I didn't!
I use tmux on a Debian machine at home, really useful for running user-initiated background programs while not logged in.
Excellent tutorial. Can you also explain the difference between apt and aptitude command? I've seen a lot (really a lot) of discussion in the internet between users using one of the other command. Can you explain which one do you think is better and why?
Thank you Sir
As always, very nice. Might want to next time also mention, sudo apt autoremove AND sudo apt autoclean. I use those pretty regularly as well.
What does each do?
Thanks!
Nice tutorial
Very nice.
Very informative.
✅✅✅✅✅
the entire concept of apt commands blow my mind. Like it seem so easy and yet so easy to mess up and install the wrong thing. it seem ssuper wierd.
Thank you
I would be interested in seeing the differences between apt 1.9 and 2.0 and 2.1 and 2.2
along with a brief comparison of dnf 3.0
nice video
We need advance tutorial for apt
This might be a recent thing, but according to the manual `apt upgrade` now actually does the upgrades that require new packages, so the difference from `full-upgrade` would be that it doesn't do upgrades requiring the _removal_ of currently installed packages. Meanwhile, `apt-get` maintains the behavior described in the video.
I laughed soooo hard at your t-shirt!
8:00 would alt+f10 work?
Is ZFS a better idea or option over LVM.
"Non-free" doesn't mean the source isn't available. Debian is quite persnickety about licenses. Anything which does not meet their narrow "open source/free software" criteria gets dumped into the "non-free" repo. Source may well be available for the package, but it's not licensed in a GPL2 type way. Matter of fact, years ago Debian dumped the RFCs because you couldn't modify RFCs and pass them on. This violated their GPLish licensing criteria (user must be able to modify the source). I've used Debian solely fo decades, but they're a little nutty sometimes.
Love the shirt! Lol
I clicked for the tutorial but the thumbs-up comes for that T-Shirt
how to install blender 4.02 with this method?
Cool
why and what is the purpose of apt-get?
i'm curious how deb packages work as in what is actually happening when it is "installing"
I think deb packages are compressed binaries of files. A script program decompresses hese binaries and copies them into the right directories or folders. Not just binaries. Including config files.
@@catayloprince4772 hmmm make me wonder how can inspect which right directories a particular deb package will extract to
Have a comment to feed the algorithm. Ty for this series.
So would
$ sudo apt-get update && apt-get upgrade -y && apt dist-upgrade -y
be a sufficient command?
I don't think so. If you are going to run that you might as well just do `apt dist-upgrade` rightaway, because the point would be to more easily evaluate the cases where new packages and, crucially, the removal of packages would be required, so you can decide whether they're worth it. It's how you avoid removing packages you need or use.
Running the `-y` option would also be unsafe for that reason.
@@fbritorufino thank you for that explanation
This was great but my sources.list file does not look like yours.
#deb cdrom:[Linux Mint 21.3 _Virginia_ - Release amd64 20240109]/ jammy contrib main
# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.
Also, when running the dist-upgrade command, I got about 50 errors `error: invalid volume.` interspersed throughout. (When i installed mint, I asked it to set up dual boot and shrink my windows partition. Seemed to go well but I can no longer boot to windows, windows install media can't even see the drive (but mint can browse it just fine).)
But why do I need to download packages all the time. Isn't that a wast of free space?
The 'q' key will quit from htop as well.
What's the difference between 'apt' and 'apt-get' ?
BTW thanks for the video
Apt combines the functionality of the apt-get and apt-cache commands and has a cleaner output. Apt-get primarily installs, removes, and upgrades packages, while apt-cache searches for and queries package information. All of these are layered over a more basic tool called dpkg that installs/removes deb package files - it doesn't know how to resolve package dependencies, nor how to pull packages from a remote repositories. The apt commands fix these limitations.
Hilarious Shirt.
What is your view about Kali-Linux
I haven’t had a use-case yet so I don’t have much of an opinion (yet).
@@LearnLinuxTV Would be great to follow you in a complete linux course. I follow you a little there a little here but would be great if you create for us a complete linux course.
minute 2.20 is where it actually starts.
nice shirt! I like it! do you consider yourself beeing one of them?
Nice basic overview of apt. You could make a follow up video about PPA, apt pinning and pre/post installation hooks.
Just for comparison i find apt rather slow and often need to add a PPA for additional software. Therefore i prefer Arch Linux with pacman, which is much faster. The AUR helper yay gives me access to pacman and nearly all software i ever wanted from the AUR. Also pacman has much better handling of pre/post installation hooks which is really handy to i.e. patch evdev after an upgrade with my custom keyboard configuration.
And even the fast pacman is really slow when compared to apk from Alpine Linux, but don't mix it up with the .apk files from android, that's something completely different.
If there only were a package manager with the speed of apk and huge package diversity of pacman+AUR... dreaming of it while setting up a ubuntu vm...
apt is absolutely not essential. Greetings from my Manjaro system. :)
ले लील्लल्ल
Great. He clears the screen instead of explaining what any of the lines of the output mean. What a waste of time
Way of explaining is too poor first explain and show practical, I watched this video on 2x eventho it's too slow 😕
