如何再次从sudo apt update命令中获得干净的输出？

感谢您的提前帮助和感谢。

Answer 1

如果你不需要sbt，你可以移除它

在Settings>Software&Updates中选择第二个选项卡ie其他软件

选择条目https://dl.bintray.com/sbt/debian并单击remove

如果你只想消除错误

使用sudo apt update --allow-insecure-repositories

Answer 2

必须首先为存储库添加公钥。

下载此链接的密钥

https://bintray.com/user/downloadSubjectPublicKey?username=sbt

然后将其添加到apt使用

sudo apt-key add sbt-public.key.asc

然后更新

sudo apt update
