WSL2（Ubuntu）sudo snap install--classic 代码不起作用

Question

我两年前就已经安装了 vscode，但今天大约 10 天后我打开了 wsl2，代码出现了以下错误（10 天前它还运行良好）

Command 'code' not found, did you mean:

  command 'cde' from deb cde (0.1+git9-g551e54d-1.1build1)
  command 'cdde' from deb cdde (0.3.1-1build1)
  command 'node' from deb nodejs (10.19.0~dfsg-3ubuntu1)
  command 'ode' from deb plotutils (2.6-10build1)
  command 'tcode' from deb emboss (6.6.0+dfsg-7ubuntu2)

Try: sudo apt install <deb name>

所以我想重新安装 VScode。但是当我输入时，sudo snap install --classic code它显示error: access denied (see 'snap help login')

systemctl status snapd.service返回以下内容：-

● snapd.service - Snap Daemon
     Loaded: loaded (/lib/systemd/system/snapd.service; enabled; vendor preset: enabled)

             └─689 /usr/lib/snapd/snapd

（是的，systemctl 在 WSL2 中默认不起作用，但我找到了一种启用它的方法）

snap version返回以下内容

snap    2.48+20.04
snapd   2.48+20.04
series  16
ubuntu  20.04
kernel  5.10.102.1-microsoft-standard-WSL2

sudo snap refresh snapd也不起作用。给出与snap install

请帮忙！
