ubuntu20.04镜像chroot之后无法apt-get update
需要再ubuntu20.04中安装gedit，file-roller，中文输入法等功能，尝试过用rsync的方法，吧所有安装好的板子上的rootfs用rsync的方法导出，但是导出后该文件系统无法自动挂载u盘，所以只能将原本的镜像mount出来之后chroot该文件系统，然后安装；但是再apt-get update的时候报错，报错信息如下：Err:1 http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports focal InRelease

可以在板子上部署好后，导出rootfs，再重新打包

您好现在还有个问题就是安装完中文后终端会有乱码，软码如下：
xinput

按照4.1导出镜像的时候直接瞬间结束，而且在对应的路径下没有产生img文件，打印信息如下：

就是插上u盘，想导出到u盘里面；只改了rootfs，就是多安装一部分功能，gedit，中文输入法，仅此而已 lional 发表于 2024-4-17 09:07

我们测试过是没问题，建议烧写默认固件再验证看下
