Ubuntu23.04安装snapd失败：E: Package ‘snapd‘ has no installation candidate

Ubuntu23.04使用apt安装snapd时报错如下：

Package snapd is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'snapd' has no installation candidate

解决办法如下：

sudo rm /etc/apt/preferences.d/nosnap.pref
sudo apt update
sudo apt install -y snapd
snap version

按照上述步骤进行操作即可顺利安装snapd。
