Feedback and issue on Xubuntu 18.10

Dear developer,

Thank you for the wonderful tool I appreciate the effort you are putting into it to make it the best tool available so far.However let me give u my feedback

I am using latest version 5.1.8

Mitn19 worked well except for the grub image after installation never worked if u run the live u get the custom image but if u install u get ubuntu image which is not mint or mine !

I decided to move my distro and base it on xubuntu 18.10 XFCE when I tried to build the iso with 5.1.8 I got the following errors:

- xubuntu 18.10 becomes very very slow un responsive when u boot it!
- Grub not found on boot message
- few more errors
- while building you get cryptsetup error
- /etc/apt/sources/*not found

I thought maybe I try 5.1.7
- on building with this non of the errors showed up
- on the end pythong showed many errors!
- At the live iso boot up was same very very slow un responsive very difficult to move the mouse!

Note all images I tried of Xubuntu are fresh no any packages were installed except pinguy and its dependencies

Its very important for me to get it working on xubuntu 18.10 XFCE based am I using the wrong version or do you have something coming up ?

Again you did great job jeep it up
