fsck.ext4 -n exited with status code 8 e2fsck 1.47.0 (5-Feb-2023) fsck.ext4: Filesystem revision too high while trying to open /tmp/1078222752.img The filesystem revision is apparently too high for this version of e2fsck. (Or the filesystem superblock is corrupt) 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 or e2fsck -b 32768
