I installed fedora last night and just left it alone, and then you come out with this. The stars just lined up

[hiram]

‘dnf history’ is very useful to understand what has been install, in what order and also to undo package installations, . Would be something good to talk about in a subsequent dnf video. Thanks for the guide.

[seanvucich]

I love the crash course series. A good middle ground between man and tldr.

[Laszlo]

Hi! I'm new to your vids and I'm glad you pronounce it soo-doo, as in "super user do" and NOT "soo-dough" which makes no sense at all and makes me grind my teeth. Thanks for the videos!

[yt_reborngameplays]

The most important *dnf history* command is not discussed. This command is what elevates dnf from apt and it allows users to rollback the updates. Actually I am happy that you haven't discussed this command in this video. I urge you to make a video about *dnf history* discretely.

Would love to see a more deep dive into dnf command.

After updating to Fedora 36 I had to use dnf modules to switch back to postgres 13 and that was a very interesting feature I wasn't aware of

[gilgarma]

So you have always good information over commands, OS's your crash courses are very good I learned a lot with, Thanks Jay!!!!

[yogeshchaudhari]

Really appreciate your work..
I am beginner for linux, this video clear some concept and helpful to how to utilize command nicely.

Waiting for next useful video like this..

[mindsoffire]

willing to learn. Unless you already understand setups, then I gues sit's gonna be easier, but as a classically trained pianist I was blown

[KeyserTheRedBeard]

wonderful content Learn Linux TV. I crushed that thumbs up on your video. Keep up the awesome work.

[StrikerEureka]

as someone who recently switched to fedora, THANKS!

[skullmammon]

hi
this is want I want to do
sudo dnf install lutris

this is the error I get
sudo: dnf: command not found

Its the same error with chmode


I would like to make these two commands to work
Im using fedora

Could you help me please

[ThisGuyFrritz]

"dandified yum." I gotta remember that when I type "dnf."

[alexaleks]

thanks for this very informative video on the best server in the universe, keep up the good work ..

/etc/dnf.conf may need also some tweaking. example:
fastestmirror=True
defaultyes=True
max_parallel_downloads=10
The defaultyes option let you just press enter instead of y+enter. Max_parallel_downloads is for fast internet connections. fastestmirror is obvious. And then you have dnf group list and then you can do sudo dnf groupinstal 'choosen group'

[binbashbuddy]

DNF is strictly for .rpm (as far as I know) packages so it only works in distros where yum is used. It's a bit like aptitude on systems that use apt (which is already really a frontend for dpkg). My understanding is that you could build and use it on other systems, but it would require converting your package managers files to .rpm before installing them which would not be worth the work.

[muzikermammoth]

How do you pin the repo to only download rpms using https? The fedora mirror redirects to usually http repos. Also the repo_gpgcheck is usually set to 0, which i take to mean files from these repos are not gpg checked.

[NoEggu]

Does "dnf" know only about the packages that it installed?

In other words, if you were previously using some other package manager, and now you want to upgrade a package, will "dnf" see that package (that was installed by a different package manager) and perform the upgrade?

And the same question for any reputable package manager. Do they all keep a common database to know what is on your system? Or do they all check, when you run your request?
Will you have conflicts or any issues if you use more than one package manager?

[Snowwolfow]

If you do the command sudo dnf install htop -y you didn't need to type the y to accept since you already did it in the command you typed

Wow Wow Wonderful Explanation....God Bless you for guiding us to learning Linux Distros.
