Matter lost my fedora entries

[VasilyKrylov]

Hello! I've recently installed matter theme, played with it and remove it. Next I tryed to install in again, but it lost my fedora entries and GRUB looks default.

sudo ./matter.py

[sudo] password for vasily:
[I] [ Matter GRUB THEME ]
[I] Argument -i required. Which icons go to which grub entries?
[I] Your grub entries are:
1. Windows Boot Manager (on /dev/nvme0n1p1)
2. UEFI Firmware Settings
[I] Look for icons you like at https://materialdesignicons.com/
[I] Then install with:
[I] ./matter.py -i icon-for-entry-1 icon-for-entry-2 ...
[I] Example (with 8 entries, _ means ignore):
[I] ./matter.py -i ubuntu microsoft-windows folder _ _ _ _ cog

config.json

hi, did you ensure that you properly configured grub beforehand?
make sure that you set GRUB_ENABLE_BLSCFG="false" in /etc/default/grub and that you've updated your grub configuration so that your changes can be detected by matter.

check this if you want more information about updating grub on fedora.

I also recommend you checking #41 and the note for fedora user in the Quick Start section for more details
