mkdir: /mnt: Read-only file system

这个错误是由于你尝试在只读文件系统上创建目录而引起的。只读文件系统是指你只能读取文件，而不能对文件进行写入或修改操作。

要解决这个问题，你可以尝试以下几种方法：

1. 确保你具有足够的权限来进行写入操作。可以尝试使用管理员权限或者使用 sudo 命令来运行该命令。

2. 检查文件系统是否已被挂载为只读模式。可以使用 mount 命令来查看文件系统的挂载状态，并确保其没有以只读模式挂载。

3. 如果文件系统是在引导过程中挂载的，那么可能需要重新启动系统以使其重新挂载为可写模式。

mount: mounting /dev/udisk on /mnt/usb failed: No such device

As an AI language model, I do not have access to your system's specific details. However, the error message indicates that the device "/dev/udisk" could not be mounted on the directory "/mnt/usb" because it does not exist.

Possible solutions are:

1. Check if the USB device is properly connected to your computer and turned on.

2. Check if the USB device is detected by your system by running the command "lsblk" or "fdisk -l".

3. Create the directory "/mnt/usb" if it does not exist by running the command "sudo mkdir /mnt/usb".

4. Try mounting the USB device using a different mount point, such as "/media/usb" or "/mnt/flash".

5. If the USB device is not recognized by your system, try using a different USB port or a different USB device.

6. Make sure that the file system of the USB device is supported by your system. For example, if the USB device is formatted as NTFS, you may need to install the ntfs-3g package to enable read and write access to the device.
