I wanted to install Debian Linux after a weird journey with Gentoo Linux. My partition layout is this:
- Boot Partition (512 MiB, mount at /boot)
- Swap Partition (4 GiB)
- Root Partition (~80 GiB, mount at /)
- Home Partition (~170 GiB, mount at /home, LUKS encrypted)
While trying to preserve the home partition, I think I clicked 'Configure encrypted partitions' on the Debian installer and then set a password for it (the same that it had before).
Now, I can unlock it like before, but after it is unlocked, no utility recognizes the filesystem (ext4) and the file
command reports it as being data
:
# file -s -L /dev/mapper/home
/dev/mapper/home: data
file
on the encrypted partition returns the following:
# file -s /dev/nvme0n1p4
/dev/nvme0n1p4: LUKS encrypted file, ver 2, header size 16384, ID 3, algo sha256, salt 0x590d84c0e8397ad0..., UUID: c5ff37db-11f7-4ccf-8869-c4bc22648202, crc 0x345f75d85c9f444a..., at 0x1000 {"keyslots":{"0":{"type":"luks2","key_size":64,"af":{"type":"luks1","stripes":4000,"hash":"sha256"},"area":{"type":"raw","offse
(This is the complete output, it cuts at offset
for some reason)
My luksDump output is this:
# cryptsetup luksDump /dev/nvme0n1p4

My guess is that I re-encrypted the already encrypted partition. Also, I noticed that the UUID changed.
Can anyone help me recover it? Thanks in advance.
If you need more logs, I will happily provide them to you.
Is there any declarative OS that is not immutable?
I tried Fedora Silverblue once and it was all fun and games until I wanted to build a driver.
But I really like the concept of declarative systems.
