What is the GUI manager for LVM in 17.10? There is no system-config-lvm that I can see.
You can install KVPM, but you have to install some KDE dependencies it has; they're not many as they said in their page. If you use some QT software it is very probable you already have the dependencies already on the system.
sudo apt-get install kvpm
system-config-lvm is outdated and can't manage some new features of LVM (as reported by itself) so don't bother trying to install it.
You can use KDE Partition Manager
sudo apt install partitionmanager
At the moment it does not work under Gnome Wayland session. So you have to use either X11 or Plasma Wayland. In the near future, KDE Partition Manager will be able to run without using root privileges (I already have most of the functionality working), then it will work much better under Wayland.
You can also allow running XWayland root GUI apps if you first run "xhost +".
EDIT: Ubuntu 20.04 has KDE Partition 4.0 which works well on Wayland.
This answer is based on comments above.
I installed an old version of
system-config-lvm from reposcope. Then i had to make sure to run on Xorg, not Wayland -- log out and choose "Ubuntu on Xorg" from the gear menu, then log in. After that i could start it just fine from the dash or command line.
If you try it on Wayland (the default), it will crash and not open.
