安装 sqlite3 时出现未满足依赖关系的问题

Question

在 ubuntu 16.04 LTS 中安装 sqlite3 时，由于未满足依赖关系，我看到以下错误，请帮我解决这个问题。

sudo apt install sqlite3
[sudo] password for dharani:

Package sqlite3 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 'sqlite3' has no installation candidate

如果执行 apt-search，它会给出以下结果。

dharani@chikki:~$ apt search sqlite3
