Mount Disk發生Not authorized to perform operation問題

突然發生這個問題，怪怪的，問了Bing Chat，原來是因為安裝了Chrome遠端桌面 ...

gnome-disks Not authorized to perform operation

Bing

您好，這是 Bing。我可以幫您解決 gnome-disks 無法執行操作的問題。

根據我從網路上搜尋到的資訊 ，這個錯誤可能是由以下原因造成的：

您沒有足夠的權限來格式化或掛載磁碟。您可能需要使用 sudo 或 gksudo 命令來執行 gnomedisks，或者使用 udisksctl 命令來解鎖和掛載磁碟。

您的系統缺少一個稱為 polkit 的驗證代理，它可以在您執行操作時要求您提供系統管理員

（root）的密碼。您可能需要安裝並啟動 polkit-gnome 或其他相關的套件。

您安裝了 Chrome 遠端桌面，它會干擾您對磁碟的存取權限。您可能需要卸載它，或者嘗試使用

其他的遠端桌面軟體。

我希望這些資訊對您有幫助。如果您還有其他問題，請隨時告訴我。

Ubuntu路徑

2. Ubuntu Updates
   https://www.ubuntuupdates.org/
3. gnu
   ftp://ftp.gnu.org/

新增Linux設備(mknod)

Usage: mknod [OPTION]... NAME TYPE [MAJOR MINOR]
Create the special file NAME of the given TYPE.

Mandatory arguments to long options are mandatory for short options too.
  -m, --mode=MODE    set file permission bits to MODE, not a=rw - umask
  -Z, --context=CTX  set the SELinux security context of NAME to CTX
      --help     display this help and exit
      --version  output version information and exit

Both MAJOR and MINOR must be specified when TYPE is b, c, or u, and they
must be omitted when TYPE is p.  If MAJOR or MINOR begins with 0x or 0X,
it is interpreted as hexadecimal; otherwise, if it begins with 0, as octal;
otherwise, as decimal.  TYPE may be:

  b      create a block (buffered) special file
  c, u   create a character (unbuffered) special file
  p      create a FIFO

NOTE: your shell may have its own version of mknod, which usually supersedes
the version described here.  Please refer to your shell's documentation
for details about the options it supports.
