I'm running fsck and getting "ext2fs_open2: Bad magic number in super-block"
I'm running:
fsck -n /dev/sdb2
and I'm getting:
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb2
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>Any advice? What's wrong with the partition and what should I do about it??

You're doing the fsck on the wrong partition (sdb2).
sudo fdisk -l shows us that the following partitions are "Linux filesystem"...
/dev/sdb4 503808 4610047 4106240 2G Linux filesystem
/dev/sdb5 4610048 32335871 27725824 13.2G Linux filesystemHere are the commands that you should be using...
Boot to Ubuntu Live DVD/USB in "Try Ubuntu" mode.
Open the terminal application and type:
sudo fsck -f /dev/sdb4
sudo fsck -f /dev/sdb5
reboot
