System not mounting swap partition

Even though the swap partition exists, and set to load in fstab, it's still not being mounted.

fdisk returns this for the swap partition:

file system: /dev/sda5
      start: 1
        end: 244
     blocks: 1951744
         id: 82
     system: Linux swap / Solaris

and in my fstab it says

file system: /dev/sda5
mount point: none
       type: swap
    options: sw
       dump: 0
       pass: 0

and I can load it fine with swapon /dev/sda5 but it just won't load at boot.

Is there more information that I can give to help troubleshoot? I dont know what other info could be useful

As requested, full fstab file:

# <file system> <mount point>   <type>  <options>            <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid  0       0
/dev/sda6       /               ext4    errors=remount-ro    0       1
/dev/sda5       none            swap    sw                   0       0
/dev/sr1        none            udf     rw,noauto            0       0

I was looking at the system log and I saw this, not sure what it means or if it's normal but:

Apr 29 17:57:24 caelan-ubuntu os-prober: debug: running /usr/lib/os-probes/50mounted-tests on /dev/sda5

output of mountall

mountall: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

swap finished
...
local 4/4 remote 0/0 virtual 12/12 swap 0/0

not sure, still not loading swap... still can be added in commandline, and my windows partition is being mounted on boot, and that is in the fstab too.
