Hoping someone will be able to help me unpick this. I have a 250GB SSD drive with a 488MiB /boot partition that is at 100%. I would like to resize the lvm2 partition to allow me to allocate more space to /boot but this is not working via kubuntu live CD using the KDE partition manager. On my kubuntu install gparted reports that only 12MiB is available however this is incorrect as the results from df -h show. KDE partition manager on the installed kubuntu doesnt manage to report a number for used space.

df -h
Filesystem                    Size  Used Avail Use% Mounted on
udev                           16G     0   16G   0% /dev
tmpfs                         3.2G  9.5M  3.2G   1% /run
/dev/mapper/kubuntu--vg-root  203G   57G  136G  30% /
tmpfs                          16G   34M   16G   1% /dev/shm
tmpfs                         5.0M  4.0K  5.0M   1% /run/lock
tmpfs                          16G     0   16G   0% /sys/fs/cgroup

/dev/nvme0n1p1                511M  3.5M  508M   1% /boot/efi
tmpfs                         3.2G     0  3.2G   0% /run/user/118

You need to first shrink LVM logical volumes and only then you can shrink LVM physical volume.

For that you need at least KDE Partition Manager 3.0.x (available in Kububtu 17.04 or various other Live CDs). No version of gparted can resize LVM logical volumes.

P.S. 12 MiB free space is exactly the space not taken up by LVM logical volumes, it is not the free space inside LVM logical partitions.

I fixed the issue of available space by cleaning the boot partition up by following this answer. Much less painful than increasing its size..

For reference the actual command is: 

dpkg -l linux-{image,headers}-"[0-9]*" | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e '[0-9]' | xargs sudo apt-get -y purge
