Proffie first attempt to program failed!

I found the solution!!! I googled my error and found a post in this forum which describes the same error:

Linux IDE issue

having a slight problem with the IDE suite when compiling in Linux. i have installed all the drivers (i think) that is needed to upload to the proffie but i keep getting this strange error message. i’ve checked that the files are where it seems to be looking for them but for the life of me i just cant figure it out why it wont see them? (i’m sure it’s a simple fix) i can see the board in ports when plugged in and i can also see the SD card so doesn’t appear to be a issue with that part. Arduino: 1.8.19 (Linux), Board: "Proffieboard V2, Serial + Mass Storage + WebUSB, SDCARD (SPI), 80 MHz, Smallest Code" fork/exec /home/driftrotor/.arduino15/packages/proffieboard/hardware/stm32l4/3.6.0/tools/linux//dfu-suffix: no such file or directory Error compiling for board Proffieboard V2. any help is happily received.

I followed the steps which Driftrotor posted, and now, I can compile

Thanks for your help @NoSloppy. The answer was out there, I just needed to find it. And, it had to be some missing Linux commands
