Hello there!
I have some problems with my Endless OS 3.3.16 and I was hoping someone could help me out…
My App Center won’t allow me to install aps like “Encyclopedia” or “Farming” and it keeps giving me an error( Can’t pull from untrusted non-gpg verified remote, and all my apps are grey
I think I might have uninstalled the most important programs from Endless
Can someone tell me what are the most important applications I need for Endless to function properly ?
Thank you <3
@dan could help 
@Andrea_Berekmeri Can you show the contents of the file /ostree/repo/config? Go to the search, enter terminal, and start the Terminal app. From there enter the command cat /ostree/repo/config. Then please copy and paste the output here. Note that copy is Control-Shift-C in Terminal. Thanks!
Actually, can you run all the same commands from Flatpack untrusted error (VLC, Transmission install)?
ls -l /etc/ostree/remotes.d
ls -l /etc/flatpak/remotes.d
ls -l /var/lib/flatpak/repo
grep -r . /etc/ostree/remotes.d /etc/flatpak/remotes.d /var/lib/flatpak/repo/config
Helllo Dan!
I entered the comand you sent and this is the “output” :

andrea@endless:~$
Also in terminal, my user name seems to be andrea@endless:~$ ( Do I have to pay for these aplications? )
Thank You 
Dan are you still here? 
Endless OS is designed around OSTree which makes it virtually impossible for a user to delete essential files. If you feel you have preformed actions that are preventing you system from behaving properly, you might wish to give yourself a fresh start, by simply creating a new user. This can be done using the settings application.
After creating a new user, you can logout or restart and log in as the new user. This should open Endless in its factory default configuration. With the new configuration you can try the update or software installs. If this works, you can just migrate your old user data over to your new account. And if it does not work, I am sorry to say that fixing the problem is beyond my knowledge.

Thank you very much for your answer and for trying to help me.
I did make a new user(administrator) … But unfortunately the problem persisted.
I think I will take my laptop to a repair shop,maybe they can help
Thank you very much again! ^.^
Hi @Andrea_Berekmeri. Sorry for the slow reply.
Everything looks normal from the response you sent. I don’t think there are any problems with your laptop, but you’re hitting an odd issue with our software. Can you try running the following command and then trying to update the system again?
sudo rm -rf /ostree/repo/tmp/cache/summaries
If you’re still having problems, can you show the output from the following commands:
flatpak remote-list -d
sudo flatpak remote-list -d
Thanks.
