kde-plasma6主题安装失败

折腾主题的时候下载主题安装失败：

The new package has a different type from the old version already installed.

遂搜到下面的文章：

can’t install the new version of polonium on plasma 6 : r/kde

详情如下：

I faced the same issue. The error complains about already installed script even though it is not visible in the settings UI.

I was able to list the script by executing plasmapkg2 -t kwinscript -l.

Attempting to remove it using plasmapkg2 -t kwinscript -r polonium did not work though.

I ended up removing the script manually with rm -rf ~/.local/share/kwin/scripts/polonium and then reinstalling through the UI.

然后顺着~/.local/share/plasma找到底下的look-and-feel目录，把里面所有文件全删掉之后就解决了。
