我试图在我拥有python3.9.2的系统上安装“锡拉”，但收到以下错误。

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 scylla-tools-core : Depends: python-yaml but it is not installable
E: Unable to correct problems, you have held broken packages.

我在编写以下命令后收到此错误。

sudo apt install scylla
