I'm installing Waydroid on Ubuntu, when running:

export DISTRO="focal" && 

sudo curl -# --proto '=https' --tlsv1.2 -Sf https://repo.waydro.id/waydroid.gpg --output /usr/share/keyrings/waydroid.gpg && 

echo "deb [signed-by=/usr/share/keyrings/waydroid.gpg] https://repo.waydro.id/ $DISTRO main" > ~/waydroid.list && 

sudo mv ~/waydroid.list /etc/apt/sources.list.d/waydroid.list && 

sudo apt update

I get the error:

curl: (77) error setting certificate verify locations:                        

  CAfile: /etc/ssl/certs/ca-certificates.crt

  CApath: /etc/ssl/certs

I'm running Ubuntu 20.04.3 LTS (Focal Fossa) and have fully updated the system.

ca-certificates is already the newest version (20210119~20.04.2).
