一个网友安装Ubuntu碰到这个问题卡住了
昨天参考的掘金网的贴文进行安装，碰到问题是Illegal instruction (core dumped),初步怀疑是显卡问题， 尝试了很久没有解决问题。也试了安装tensorflow。
今天重装了一下系统， 然后选择了官网的源代码开始安装
https://conflux-chain.github.io/conflux-doc/install/
其中碰到了2个问题值得注意：
1.碰到db错误， 我们开始用的是官网的0.1.7， 后来查询到该版本有这个问题，随后切换到0.2.1
总结， 其实安装过程还是比较消耗时间的， 如果有一些工具能让下载速度快一点会比较好， 整个安装差不多花了2个小时， 如果注意到上面的几点， 应该能再40分钟内搞定。
大家如果碰到Ubunt安装的问题可以在该贴文下面留言，如果解决不了，可以按照Teamviewer， 我们远程登录你电脑帮助解决。

好文
Ubuntu系统运行conflux(先chmod 777 conflux过),执行./conflux --config default.toml --full 2>stderr.txt时，请问这是什么问题？!
执行这个，看看报什么错误
./conflux --config default.toml --full 2
一样的报错，权限不够。我在属性中沟上"可执行程序"但那个对沟被迅速撤销
后来我发现以上图片中出现的问题，运行的文件放在了Windows分区（我是双系统）。。。虽然Linux下看得到但权限是没有
于是把conflux文件夹移动到Ubuntu分区，但由于我系统版本是20.04版本，报错：核心已转储
于是我下载源代码编译启动的挖矿
我这个就是描述在0.5.1-alpha-4（友好版）这个版本发生的情况：后来我发现以上图片中出现的问题，运行的文件放在了Windows分区（我是双系统）。。。虽然Linux下看得到但权限是没有

你可以安装一个teamviewer， 加我微信 1725325128， 我远处到你电脑看看。
