Hi,
I’ m new on Linux, ( spent a little of time on Ubuntu), completely new at Endeavour OS.
I’d like to ask how can I find apps that I’d like to install. On Ubuntu there was ‘app store’, can’t see it here. Can I install something like that on Endeavour ?
Hi and welcome!
In Arch based distros like Endeavour we use the Arch repository’s using terminal. There are the official Arch “repo”, and the AUR (Arch User’s Repository).
The ordinary Arch repo can be found and searched (under Package search) here:
The AUR can be found and searched here:
The command to install a package in terminal is:
sudo pacman -S “package name”
The command to install from AUR (and the ordinary repo) is:
yay -S “package name”
Then you’ll be prompted to type in your password, and the package will install. In yay there are further steps, but generally hitting “enter” does the trick.
Don’t hesitate to ask if there’s something you’re wondering about. 
PS. Endeavour has an excellent wiki that you might consider reading. DS
In addition there is always Arch’s own Wiki which is one of the most comprehensive Linux Wikis:
https://wiki.archlinux.org/index.php/Main_page
I forgot to post the wiki entries on the subject:
a very useful command is: yay -Ss "app name"
This lets you search all the repos.
You may also want to install Pamac.
That is my app-store.
You may try yay -S pamac-aur-git which installs pamac on your system. @FredBezies is the maintainer. Downside is that you currently need to downgrade as described here in order to browse the categories.
you can always install gnome-packagekit for kde/qt apper if you do pcurses in terminal you have also some things
It depends what you mean by “App Store”.
All the applications mentioned above are what I would call “Package Managers”. By that I mean that provide a way to manage packages which could be an application, like Firefox, or could be an underlying system library like libnss. For perspective, there are many thousands of packages available between the repos and AUR. For comparison, on Ubuntu, the package manager is apt and a common graphical package manager is Synaptic.
On the other hand, if you are talking about something like the Ubuntu Store, which lets you browse through a curated list of applications and doesn’t include any of the other system-related packages, I don’t think there is anything as comprehensive as what has been mentioned above. However, there are a couple of options available.
KDE Discover and Gnome Software are much more like an App Store. They support repo packages and flatpaks(if flatpak is installed) but not the AUR.
Keep in mind, if you aren’t running plasma or gnome installing those applications will probably pull in quite a few dependencies.
Ups…didn’t see that you were faster!
I added a patch found on manjaro gitlab which fixes appstream-data bug.
Added back in this commit on may 16.
Well, after this… 
You’re awesome, Fred! I’ll be switching back to your git version, then.
