apcupsd help "Read-only file system error"

[fals3illusion]

I just upgraded my proxmox ve server to new hardware and I am having trouble getting my APC UPS's working on a debian lxc with apcupsd.

This is the main resource I followed along with a lot other research to finally get it working on the old system. Everything was working before I moved to a new pve server.
https://wiki.debian.org/apcupsd#Installation

in my lxc config I am passing through
lxc.mount.entry: /dev/usb dev/usb none bind,optional,create=dir

I have 6 UPS's that are all on 1 hub connected to one of my USB ports on the back of my pve server..
I have a rules file
nano /etc/udev/rules.d/ups.rules

# Back-UPS RS Middle 1500MS Shelf -- middleShelf
KERNEL=="hiddev*", ATTRS{manufacturer}=="American Power Conversion", ATTRS{serial}=="SerialXXX", OWNER="root", SYMLINK+="usb/ups-middleShelf"

# Smart-UPS Right 1000 Shelf -- rightShelf
KERNEL=="hiddev*", ATTRS{manufacturer}=="American Power Conversion", ATTRS{serial}=="SerialXXX", OWNER="root", SYMLINK+="usb/ups-rightShelf"

# Smart-UPS Left 1500 Shelf -- leftShelf

# Smart-UPS Bottom SRT Rack -- bottomSRTrack
KERNEL=="hiddev*", ATTRS{manufacturer}=="American Power Conversion", ATTRS{serial}=="SerialXXX", OWNER="root", SYMLINK+="usb/ups-bottomSRTrack"

then using this command udevadm trigger --verbose --sysname-match=hiddev*
I am trying to map /SYMLINK the ups's and I am getting this error.

Any idea how I can try and fix this?

Thanks!

I found a workaround, that makes it work.
Not sure if this is correct and not supposed to do it on the host level or if I it is best practice to only do it on the container level.

On the proxmox HOST, I created my ups.rules files after, then I ran the udevadm trigger --verbose --sysname-match=hiddev* and it linked all of the files and it started communicating!
