dual boot - Can't shrink Ubuntu partition Gparted ERROR (238277632K 00:00:05)

I am using 'Gparted live USB' and I receive the error log (below) when I try and shrink my Ubuntu partition. I don't know what the error means or what is causing it.

I have Windows 10 and Ubuntu 16.04 installed on the same machine (Dell Inspiron 3521 specs). When I first installed, I formatted a black space of roughly 40GB on my internal HDD (Using Windows disk management) and installed Ubuntu on that. Ubuntu installer automatically divided that into roughly 36GB OS partition and 3.88GB SWAP space. Since then I have needed more space on Ubuntu so I shrank my Windows partition (dev/sda5) and extended my Ubuntu partition (dev/sda9) (See screen-shot link below). Did this using Gparted live USB boot and it all worked fine. Gparted version: gparted-live-0.26.0-2-i686.ios

Please see partitions here (Gparted screen-shot)

Now I want to create more SWAP space since I could actually do with about 8GB SWAP so I want to shrink Ubuntu (dev/sda9) and then expand SWAP (dev/sda10). There is definitely enough free space on dev/sda9 (I am only trying to shrink by 4.02GB and there is 208.93GB available). But when trying to shrink Ubuntu I get this ERROR:

shrink file system  00:00:05    ( ERROR )

Any help appreciated.

I am a bit of a new-be to Ubuntu (5 days now) so I may have easily overlooked something obvious.

Thanks!

This question was answered on the GParted Forum. See Can't shrink partition - ERROR 238277632K 00:00:05.

The TL;DR is to use live media with e2fsprogs < 1.43 such as GParted Live 0.25.0-3 in the meantime until the base issues can be addressed.
