各位哥哥姐姐帮帮忙看一下是什么原因，感谢！

你标题我就没看懂“ubuntu18.04.5安装xubuntu”是个什么操作
你贴出来的第一行就是报错的直接原因，安装时无法写入日志。具体是执行posix_openpt函数失败，错误代码是无法找到设备。疑似/dev/pts没有被挂载。
另外同一个帖子不要在不同的版重复发，并不会增加你帖子的曝光度

不仅仅是apt upgrade会错，apt-get install任何软件都会报一下错误，软件源换过了，也一样。实在没办法了

恭喜，系统已经被你搞坏了，重装去

[莫运镇]

现在不是修复系统的东西，现在是制作ubuntu18.04.5的rootfs.img镜像文件，然后在安装桌面系统的时候报这个错误。软件源我已经更改过阿里云的，也是没有作用的

我就奇怪了，上面那么几行报错内容，你从哪里看出来是和软件源有关了？我上面都跟你说了是什么错，还在那里瞎猜瞎蒙瞎碰是吧？

现在不是修复系统的东西，现在是制作ubuntu18.04.5的rootfs.img镜像文件，然后在安装桌面系统的时候报这个错误。

我不知道你是从那里看到的制作方法，如果是用了chroot，那大概率是你没有将/dev/pts挂载到chroot环境里去

还有，以后提问把前因后果描述清楚，别只扔一段报错文本，减少彼此时间的浪费

[莫运镇]

好的，下次不发了
