I'm testing the beautiful installable Plasma ISO.
I have tried to run Mailspring after installing it through snap and also through eopkg, but in both cases Mailspring refuses to start with this message:
Mailspring could not store your password securely. Make sure you have 'libsecret' installed and a keyring is present. For more information, visit http://support.getmailspring.com/hc/en-us/articles/115001875571
The package libsecret is intalled, but this makes no effect. I went to the support link, and also says that the cause could be gnome-keyring not being installed (which makes sense).
