dpkg前端锁被进程占用，无法彻底卸载yt-dlp的问题求助

我最近正尝试用Synaptic包管理器彻底卸载yt-dlp，试了网上的不少方案都没解决——重启系统没用，移除lock-frontend也不管用。

另外我发现系统里存在多个youtube-dl相关文件，用自定义脚本查找后得到以下结果：

~$ Find_File.sh youtube-dl
Searching for youtube-dl
/home/andy/Downloads/youtube-dl
/home/andy/.local/bin/youtube-dl
/home/andy/.local/share/pipx/venvs/youtube-dl
/home/andy/.local/share/pipx/venvs/youtube-dl/bin/youtube-dl

现在还碰到了dpkg锁占用的问题，具体报错信息如下：

dpkg: error: dpkg frontend lock was locked by another process with pid 8452
Note: removing the lock file is always wrong, can damage the locked area
and the entire system. See https://wiki.debian.org/Teams/Dpkg/FAQ#db-lock.
E: Sub-process dpkg --set-selections returned an error code (2)
E: Couldn't record the approved state changes as dpkg selection states
A package failed to install. Trying to recover:

想请教大家，我还能尝试哪些方法来解决这个问题？
