升级到 ubuntu 19.10 后删除桌面并且不安装 xfce4

在我安装 xfce4 之后

sudo apt-get install xfce4

中途我的网络断开了,我尝试再次安装,但出现了如下错误:

W: Not using locking for read only lock file /var/lib/dpkg/lock-fronted
W: Not using locking for read only lock file /var/lib/dpkg/lock
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

我跑完后dpkg --configure -a出现这个错误:

dpkg: error: unable to access the dpkg database directory /var/lib/dpkg: Read-only file system

我登录 Linux 后重新安装了 Linux,但仍然无法在操作系统上安装任何应用程序。我上传了 dmesg.txt 文件,您可以在以下链接中下载

当我使用该sudo mount / -o remount,rw 命令时,我得到了:

mount: /: cannot remount /dev/sda7 read-write, is write-protected.
