I recently installed Ubuntu 20.04. Considering the time that passed since its release I thought it would be stable. After installing it, I go to Snap Store (named Ubuntu Software) and I see that several new programs appear, but after a few moments, only the editor picks show, nothing else.
I try to install PyCharm through the command line with snap,
sudo snap install pycharm-community --classic but it gives me this error: x509: certificate signed by unknown authority.
Afterwards, I decide to purge snap store and reinstall it, and after running these 2 commands:
sudo apt-get update ,
sudo apt install snapd , I enter this one
sudo snap install snap-store and gives me again, the same error with the certificates.
I got no idea whats going on. I installed it from 0
Edit 1 :
snap list :
No snaps are installed yet. Try 'snap install hello-world'.
sudo snap install snap-store :
error: cannot install "snap-store": Post https://api.snapcraft.io/v2/snaps/refresh: x509: certificate signed by unknown authority
