参考此link,我将ROS2 Eloquent安装到我的Ubuntu 18.04.4 LTS中。
我的系统信息如下(通过 uname -a )
Linux myname 5.3.0-28-generic #30~18.04.1-Ubuntu SMP Fri Jan 17 06:14:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
我可以设置区域设置和设置源,没有问题。然后,是安装ROS 2软件包。
运行 sudo apt更新后,我运行 sudo apt install ros-eloquent-desktop ,它返回:

我截断了答复,只保留了我认为可以帮助您了解问题的最后一部分。我用谷歌搜索,但找不到解决方案。我也没有安装任何防火墙和防病毒软件。
请帮助。非常感谢。

我实际上已经解决了我的问题,但是我认为您的方式更合适。如果将来我遇到类似的问题,它可以作为我的补救措施。无论如何,我所做的是:
我最终直接从http://security.ubuntu.com/ubuntu/pool/main/g/gcc-7/gcc-7_7.5.0-3ubuntu1~18.04_amd64.deb下载了deb软件包,然后通过命令进行安装(参考:https://unix.stackexchange.com/questions/159094/how-to-install-a-deb-file-by-dpkg-i-or-by-apt)
let timed = "10s"
const tests = new Discord.RichEmbed()
.setTitle("tets")
.setColor('#000000');
var testMsg = message.channel.send(tests).then(
setTimeout(function(){
tests.setColor('#5e4242');
testMsg.edit(tests); // edit the message with the same object but different color
}, ms(timed));
)
break;
然后,我能够安装ros-eloquent-desktop。
