Ubuntu 24.04 LTS下挂载GPT分区的FAT格式USB设备，安装exfat工具包失败求助

大家好，我最近在Ubuntu 24.04 LTS上折腾我的USB设备挂载，遇到了点麻烦想请大家帮忙看看。

首先我用sudo fdisk -l命令查看了设备信息，结果如下：

Disk /dev/sdb: 241.87 GiB, 259710255104 bytes, 507246592 sectors
Disk model: SD Card Reader  
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 5F610759-0934-4674-96A8-0F49DB6C7B1A

Device      Start       End   Sectors   Size Type
/dev/sdb1      40    409639    409600   200M EFI System
/dev/sdb2  411648 507244543 506832896 241.7G Microsoft basic data

我之前参考了社区里的一个解决方案，尝试安装exfat相关工具来挂载这个设备，但执行sudo apt-get install exfat-fuse exfat-utils命令时失败了，报错信息如下：

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package exfat-utils is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only...

有没有大佬知道这是怎么回事，该怎么解决呢？
