When trying to install core20 on an armhf unit, there is error:
Download snap " core20" (633) from channel "stable" (received an unexpected http response code (404) when trying to download https://api.snapcraft.io/api/v1/snaps/download/DLqre5XGLbDqg9jPtiAhRRjDuPVa5X1q_633.snap)
So I tried to download the snap:
sudo snap download core20
And I can download it then install it, which is my workaround but maybe snap store still need some fix.
OS: Ubuntu server 20.04
