I am trying to install Indicator Keylock for Ubuntu 17.10, but when adding the repository I get the following error:
E: The repository 'http://ppa.launchpad.net/tsbarnes/indicator-keylock/ubuntu/' 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.
Anyone could help me with this issue?
