Please include your question in the body as well. The subject should be
a summary of the email, not part of it.

df shows mounted filesystems. So your sda5 is not mounted.

Since it seems to be a LUKS encrypted volume, it cannot be mounted, but
rather it's contents can be decrypted and mounted (sda5_crypt).

... Except that sda5_crypt seems to be a LVM physical volume, so you
don't mount that directly either, you mount the logical volumes.
/dev/mapper/lbrtchx--vg-root seems to be one of those volumes.

Try running lsblk, it should show the device tree.
