Ubuntu 17.10的指标Keylock

我正在尝试为Ubuntu 17.10安装Indicator Keylock,但在添加存储库时,我收到以下错误:

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. 

任何人都可以帮我解决这个问题?

这意味着, PPA没有巧妙的包装 。

只需删除此PPA并使用以下命令从官方存储库安装软件包:

 sudo apt-get install ppa-purge sudo ppa-purge ppa:tsbarnes/indicator-keylock sudo apt-get update sudo apt-get install indicator-keylock
