报错信息很直观，大概率是因为 vscode-server.tar.gz 下载后通过gzip解压失败导致的，初步怀疑是网络原因，进行了多次下载且搜索了microsoft/WSL · Issue #4461 后排除了网络原因，并确定是当前版本安装的 gzip 的问题：

gzip/jammy,now 1.10-4ubuntu4 amd64 [installed]

索性开源社区已经给出了解决方案，安装一个旧版本的 gzip-1.9-3：

$ wget http://launchpadlibrarian.net/406169458/gzip_1.9-3_amd64.deb
$ sudo dpkg -i ./gzip_1.9-3_amd64.deb
$ sudo apt-mark hold gzip	# 取消更新
$ sudo apt-mark unhold gzip # 恢复更新
