Ubuntu 22.04中~/.local/bin自动加入PATH的原因排查求助

各位好，我在新安装的Ubuntu 22.04上碰到了PATH配置的奇怪问题。最开始~/.local/bin在PATH里出现了两次，我通过注释掉~/.profile里的相关代码块把它改成了一次，但现在我彻底搞不懂~/.local/bin最初是怎么被加到PATH里的——默认路径里没有它，.profile里我已经注释掉了相关设置，.bashrc里也没找到对应的配置项。

我当前执行echo $PATH的输出结果是：

dave@local $ echo $PATH
/home/dave/.local/bin:/home/dave/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

下面是我的.profile文件内容：

dave@local $ cat .profile 
# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask
# for ssh logins...

有没有大佬能帮我分析下，到底是哪个环节在自动把~/.local/bin添加到PATH里的？
