Eu tenho um problema como esta pergunta Como o disco se tornou subitamente protegido contra gravação apesar da configuração ser de leitura/gravação?

E eu usei esses comandos para resolver isso umount /dev/sdb1 e2fsck /dev/sdb1 mount /dev/sdb1

mas

~# 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

comandos adicionais para ajudá-lo a conhecer detalhes adicionais

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

mkdir /DATA

mount /DATA

~# ls -lat | grep DATA

~# umount /DATA
~# e2fsck /DATA

e2fsck: Is a directory while trying to open /DATA

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>

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

Enfim, gostaria de acessar este hard /dev/sdb1 na pasta /DATA

Como posso resolver este problema?

Na minha atualização do freebsd 11 para o FreeBSD 12 recebi uma mensagem de erro ld-elf.so.1: /bin/sh: Undefined symbol "stat@FBSD_1.5" reiniciei meu SO e agora o erro continuou ld-elf.so.1: /bin/sh: Undefined symbol "stat@FBSD_1.5" enter full pathname of shell or return for /bin/sh: e quando quero digitar qualquer comando vejo esta mensagem cannot execute COMMAND for single user: no such file or directory Claro, iniciei meu FreeBSD com modo de usuário múltiplo, mas aparece essa mensagem quando quero usar a tecla Enter para qualquer comando escrito, como posso resolver esse problema?

Eu gostaria de criar um arquivo com: nome:

Hyper

comando executar:

"/opt/Hyper/hyper" %U

ou nome:

Google Chrome

comando executar:

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

(quando clicamos neste ícone, ele abre o Google Chrome)

ou nome:

FileZilla

comando executar:

filezilla

O comando "touch" pode nos ajudar a criar um arquivo, mas não sei como posso definir o comando a ser executado para todos os arquivos criados

este arquivo é como o ícone da área de trabalho, ou ícones na barra de menus (ou barra de aplicativos) quando criamos um ícone na área de trabalho com ln -s, criamos um Link Simbólico, mas este não é basicamente o link do nosso programa.

Claro, podemos copiar qualquer ícone de programa para outro caminho, mas basicamente não sabemos onde estão nossos programas.

Eu gostaria de criar um ícone para meus programas instalados para outro caminho, por exemplo, quando abrimos o menu do aplicativo, podemos ver o ícone do leafpad e o nome do ícone é:

leafpad e o comando para executar o leafpad é: leafpad %f

Eu gostaria de criar qualquer ícone de programa, como ícones no menu do aplicativo, para qualquer pasta que eu precise.

Espero que minha explicação tenha sido suficiente.

obrigado à frente

Quando eu quero instalar qualquer pacote como o gedit:

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

A saída é:

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: libgtksourceview-3.0-1 (>= 3.21.5) 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

E quando usamos:

**apt --fix-broken install**

Nós vemos:
