When following this guide: https://wiki.winehq.org/Ubuntu
To install the development or staging versions of Wine, I get this when I try to update:
E: The repository 'https://dl.winehq.org/wine-builds/ubuntu flidas Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
Is it possible to enable such a feature through GUI?
