The Snap Store Proxy was originally released in beta form as the 'snapstore' snap. This has now been renamed to 'snap-store-proxy'.
Migrating the new snap is straightforward, but may involve a few seconds of downtime.
To migrate to the new snap, take the following steps:
First, install the new snap:
sudo snap install snap-store-proxy
Then, copy across the configuration to the new snap:
sudo snap get -d snapstore | sudo snap-store-proxy.migrate-from-beta
You can check the new snap's status:
In order to start the new snap, we must first stop the old one:
sudo snap stop snapstore # downtime here sudo snap restart snap-store-proxy
And finally, once you're happy with the migration:
sudo snap remove snapstore
