Package synaptic 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 'synaptic' has no installation candidate

Answer 1

Synaptic 在存储库中可用universe。如果您收到此错误，则意味着您尚未启用它。

要启用它，请打开Software & Updates，
然后选中旁边的复选框Community-maintained free and open-source software (universe)

然后
sudo apt-get update
sudo apt-get install synaptic
