在Ubuntu终端安装Xilinx时无法解决Java Sun图形环境错误

此前在Windows 11笔记本搭建RedPitaya生态系统时遇到问题，现换用Windows 10台式机尝试。通过微软商店安装Ubuntu 20.04.5 LTS，并将系统伪装为18.04.4以规避Xilinx安装程序兼容性问题，随后执行以下命令安装Xilinx Unified 2020.1：

chmod +x ./Xilinx_Unified_2020.1_0602_1208_Lin64.bin
sudo ./Xilinx_Unified_2020.1_0602_1208_Lin64.bin

但遇到如下错误：

ERROR: Installer could not be started.
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
java.awt.HeadlessException:

尝试设置DISPLAY变量为localhost:0.0、:0.0、:0或取消设置后，均出现新错误：

之前在笔记本安装Xilinx时，曾通过以下命令安装OpenJDK解决问题，但台式机上此方法无效：

sudo apt-get install openjdk-6-jdk
sudo apt-get install openjdk-6-jre

已尝试OpenJDK和Oracle的Java 8、17、19等版本，安装方式包括.tar.gz文件、软件仓库及终端命令，当前使用的Java版本为：

java version "17.0.1" 2021-10-19 LTS
Java(TM) SE Runtime Environment (build 17.0.1+12-LTS-39)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.1+12-LTS-39, mixed mode, sharing)

仍无法解决报错。当前系统为x64 Windows 10 Home 21H2（OS Build 19044.2251），无法升级至Windows 11（错误码0xc1900101），使用WSL安装Ubuntu后结果一致，恳请提供解决方法。
