Problems setting up a real time clock on pi 3 b+ retropie 4.4

[edmaul69]

so i used to use my ds3231 rtc with no issues on 4.3. i have been through several guides and cant get it working. it sees it when i type:

sudo i2cdetect -y 1

after all the setup stuff i type:

sudo update-rc.d hwclock.sh enable

and i get this error and i dont know how to fix it:

insserv: Service mountdevsubfs has to be enabled to start service hwclock

any help would be greatly appreciated. if you need further details of all steps done in setting this up please let me know

i also get this error when i run hwclock commands:

pi@retropie:~ $ sudo hwclock -w
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --debug option to see the details of our search for an access method.

i also get this error:

pi@retropie:~ $ sudo modprobe rtc-ds1307
pi@retropie:~ $ sudo bash
root@retropie:/home/pi# echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
bash: echo: write error: Invalid argument
root@retropie:/home/pi#

@edmaul69 did you try echo "ds1307 0x68" > /sys/class/i2c-adapter/i2c-1/new_device

Assuming h68 is correct adress for this device?

@cyperghost with or without the parentheses its the same. One other thing I noticed is when i run “sudo i2c-detect -y 1” it says 68. It never changed to UU even though i put the info in my /boot/config.txt
