我有这样的问题 尽管配置是读/写的，但磁盘如何突然变得写保护？

我使用这些命令来解决这个问题 umount /dev/sdb1 e2fsck /dev/sdb1 mount /dev/sdb1

但

~# e2fsck /dev/sdb1
e2fsck 1.44.5 (15-Dec-2018)
ext2fs_open2: Bad magic number in super-block
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdb1

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

/dev/sdb1 contains a ufs file system

其他命令可帮助您了解其他详细信息

~#nano /etc/fstab
UUID=###951671### /DATA ufs defaults 1 2

mkdir /DATA

mount /DATA

~# umount /DATA

The superblock could not be read or does not describe a valid ext2/ext3/ext4

filesystem (and not swap or ufs or something else), then the superblock

 or
    e2fsck -b 32768 <device>

~# mount /DATA
mount: /DATA: WARNING: device write-protected, mounted read-only.

根本，我想访问 /DATA 文件夹中的这个硬 /dev/sdb1

我该如何解决这个问题？

在我从 freebsd 11 升级到 FreeBSD 12 时，我收到一条错误消息 ld-elf.so.1: /bin/sh: Undefined symbol "stat@FBSD_1.5" 我重新启动了我的操作系统，现在错误继续 ld-elf.so.1: /bin/sh: Undefined symbol "stat@FBSD_1.5" enter full pathname of shell or return for /bin/sh: ，当我想输入任何命令时，我看到了这条消息 cannot execute COMMAND for single user: no such file or directory 当然，我以多用户模式启动了我的 FreeBSD，但出现了这条消息当我想对任何书面命令使用 Enter 键时，我该如何解决这个问题？

我想创建一个文件：名称：

Hyper

命令运行：

"/opt/Hyper/hyper" %U

或名称：

Google Chrome

命令运行：

/usr/bin/google-chrome-stable --no-sandbox

（当我们点击这个图标时，它会打开谷歌浏览器）

或名称：

FileZilla

命令运行：

filezilla

“touch”命令可以帮助我们创建文件，但我不知道如何定义命令为每个创建的文件运行

这个文件就像桌面图标，或者菜单栏（或应用程序栏）中的图标，当我们使用 ln -s 在桌面创建图标时，我们创建了一个符号链接，但这基本上不是我们的程序链接。

当然，我们可以将任何程序图标复制到另一个路径，但我们基本上不知道我们的程序在哪里。

我想为我安装的程序创建图标到其他路径，例如，当我们打开应用程序菜单时，我们可以看到 Leafpad 图标，这个图标名称是：

Leafpad 和运行 Leafpad 的命令是：leafpad %f

我想在我需要的任何文件夹中创建任何程序图标，例如应用程序菜单中的图标。

我希望我的解释已经足够了。

提前谢谢

当我想安装像 gedit 这样的任何包时：

sudo apt-get clean
sudo apt-get autoclean
apt install gedit

输出是：

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 gedit : Depends: libgspell-1-1 (>= 1.0.0) but it is not going to be installed

         Depends: libpeas-1.0-0 (>= 1.14.1) but it is not going to be installed

         Depends: gir1.2-gtksource-3.0 but it is not going to be installed
         Depends: gedit-common (>= 3.22) but it is not going to be installed

当我们使用：

**apt --fix-broken install**

我们看：

dpkg: error processing archive /var/cache/apt/archives/libwinpr2-2_2.0.0~git20170725.1.1648deb+dfsg1-7~bpo9+1_amd64.deb (--unpack):

或者当我使用这个命令时：

aptitude install

我看到此错误消息：
