无法安装 Filezilla，找不到软件包 [重复]

我sudo apt-get install filezilla在 Lubuntu 上运行，但它回来说它找不到包。具体来说E: Unable to locate package filezilla3

我已经尝试过更新、清除和更新，但找不到它。找不到其他有这个问题的人。FileZilla 说尝试使用包管理器来获取 Filezilla。我尝试了他们的二进制文件，但它要求我选择一些东西来运行它。在 apt-get 更新期间，我确实收到几行说它无法启动连接。

哦，我用二进制文件尝试了 ./filezilla，它说找不到文件。

我使用的是 Lubuntu 19.04 版。

apt-get 更新的输出
