Ubuntu 16.04 and later with systemd
You do an fsck at every boot with some kernel parameters…
sudo nano /etc/default/grub
find the line that says
GRUB_CMDLINE_LINUX_DEFAULT
and add
fsck.mode=force fsck.repair=yes
to the existing things there.

Ubuntu 16.04 and earlier without systemd
The answer to your question is here [How can I make fsck run non-interactively at boot time?1
File System Check (fsck) isn’t run every boot so your “once in a while” could mean errors are always there but fsck isn’t run when no errors are reported.
Finding the source of file system errors is important. I would take a look at the error messages in /var/log/boot.log and post a new question of what errors there you need help with. Fsck error messages can be in other locations depending on whether upstart or systemd is used for init at boot time.
To force Ubuntu to fix all disk errors at boot you need to add FSCKFIX=yes to the file /etc/default/rcS. This tells fsck to run with the -y flag. 1
