我收到关于不安全所有权的警告~/.gnupg：

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo gpg --dearmor -o /usr/share/keyrings/githubcli-archive-keyring.gpg
  gpg: WARNING: unsafe ownership on homedir '/home/USER/.gnupg'
  • 我尝试了以下方法，但没有任何效果： 
    chown -R $(USER) ~/.gnupg/

    find ~/.gnupg -type f -exec chmod 600 {} \;
find ~/.gnupg -type d -exec chmod 700 {} \;

    sudo gpgconf --kill dirmngr
sudo chown -R USER:USER /home/USER/.gnupg
chmod 700 /home/USER/.gnupg
chmod 600 ~/.gnupg/*

  • ls -al /home/elias/.gnupg

根据我的理解，rsync没有-oand-g选项意味着在不更改目标所有者和组的情况下进行复制。但是，我发现了一种rsync我无法解释的非常奇怪的行为。一个例子总是比冗长的解释好：

设file1和file2为 2 个文件，其组和所有者分别为 user1:user1 和 user2:user2。

运行以下指令（在 2 行中）user1是一个 sudoer：

touch file1

然后

touch file2 && sudo chown user2:user2 file2 && rsync file1 file2 && ls -l

结果是：

-rw-r--r-- 1 user1 user1 0 Jan 16 19:51 file1
-rw-r--r-- 1 user1 user1 0 Jan 16 19:53 file2

在运行以下指令时，仍然使用user1，一次（1 行）：

touch file1 && touch file2 && sudo chown user2:user2 file2 && rsync file1 file2 && ls -l

结果是：

-rw-r--r-- 1 user1 user1 0 Jan 16 19:51 file1
-rw-r--r-- 1 user2 user2 0 Jan 16 19:53 file2

总而言之，在第一种情况下，所有权file2已被修改，而在第二种情况下，它还没有被修改，它仍然是 user2:user2，这是预期的行为（除非我误解了）rsync。

也许我错过了什么，但我找不到什么。请问您有什么解释吗？

先感谢您。
