I encountered some errors when installing the Parrot sec OS 5.2. This is the error message provided by the installer: ![](https://i.sstatic.net/dNs91.png) My computer supports UEFI mode and BIOS mode, and I have tried to use Rufus and BalenaEtcher USB flash disk burning software, and I have also tried MBR mode and UEFI mode, and I have also tried to install USB flash disk in GPT format and MBR format. However, these operations have no effect. The error prompt still pops up. This makes it impossible for me to install this system. After this error prompt pops up, I can't mount this partition in Ubuntu system. If this is due to the problem of python code in this installation program, please tell me how to solve it (I am able to write python code, not a novice). If this problem has nothing to do with python code, please tell me how to handle it correctly.
