I am using Elementary OS 5.0 for a while. Today I just installed 5.1. In the appcenter the amount of the app is less than it should be. To give an example most common apps like Libreoffice, Octave, Spyder cannot be found in the appcenter. During whole day, I couldn't find any way to solve this. I am asking your help. Have a good day. Thank u for your interest. Here, the screenshot from the appcenter.
I just updated my home computer in Elementary OS 5.1 HERA
Looking for each of your application, on my laptop still under EOS 5.0 and my home computer under EOS 5.1
I find exactly the same result on the appcenter to know
checked the contents of your source list of the app center, now here is mine in my Elementary OS 5.1 HERA
$ cat /etc/apt/sources.list.d/appcenter.list deb http://packages.elementary.io/appcenter bionic main $ cat /etc/apt/sources.list.d/elementary.list deb http://ppa.launchpad.net/elementary-os/stable/ubuntu bionic main deb-src http://ppa.launchpad.net/elementary-os/stable/ubuntu bionic main $ cat /etc/apt/sources.list.d/patches.list deb http://ppa.launchpad.net/elementary-os/os-patches/ubuntu bionic main deb-src http://ppa.launchpad.net/elementary-os/os-patches/ubuntu bionic main
