Ubuntu 22.04执行snap refresh时出现签名验证错误求助

大家好，我在Ubuntu 22.04系统上执行sudo snap refresh命令时碰到了一个签名验证的错误，折腾了半天在网上也没找到相关的解决办法，想请各位大佬帮忙看看！

执行sudo snap refresh后的报错信息如下：

sudo snap refresh
error: cannot perform the following tasks:
- Fetch and check assertions for snap "snapd" (21759) (cannot verify snap "snapd", no matching signatures found)

我的snap版本信息：

snap version
snap    2.62+22.04
snapd   2.62+22.04
series  16
ubuntu  22.04
kernel  6.5.0-35-generic

snap list --all的输出内容：

snap list --all
