cryptsetup open and see if you get a meaningful error.
cryptsetup --help to get information on the exact syntax you need to unlock it.
It seems You are on KDE DE ?
Otherwise you can use gnome-disks to open encryption and mount graphically encrypted partitions …
i can’t do it can you help with exact command
It is something like:
sudo cryptsetup open /dev/sdxn myluks
/dev/sdxn with the block device that has luks on it.
If you don’t know what that is then please share the output of
lsblk -o name,fstype,label,type,size
sda1 crypto_LUKS part 226.7G $ sudo cryptsetup open /dev/sda1 myluks [sudo] password for ararch: Enter passphrase for /dev/sda1:
So now it is unlocked. You can mount it now. It should have created a new block device
/dev/mapper/myluks. Mount that somewhere.
$ sudo cryptsetup open /dev/sda1 myluks [sudo] password for ararch: Enter passphrase for /dev/sda1: $ sudo mount /dev/mapper/myluks /mnt/myluks mount: /mnt/myluks: wrong fs type, bad option, bad superblock on /dev/mapper/myluks, missing codepage or helper program, or other error. dmesg(1) may have more information after failed mount system call.
Can we see
lsblk -o name,type,fstype,size,mountpoint
$ lsblk -o name,type,fstype,size,mountpoint NAME TYPE FSTYPE SIZE MOUNTPOINT sda disk 931.5G ├─sda1 part crypto_LUKS 226.7G │ └─myluks crypt 226.7G ├─sda3 part 1K ├─sda4 part ext4 390.1G ├─sda5 part btrfs 146.5G ├─sda6 part ext4 300M /boot └─sda7 part btrfs 166.9G / sr0 rom 1024M zram0 disk 1.7G [SWAP]
What filesystem was on that luks device?
It is either corrupt or it is something that lsblk can’t recognize.
Also, why do you have a 1k partition?
this was a /boot now it has no use
