All these years, I've used the old FM files monitor
https://www.mobileread.com/forums/sh...2&postcount=76 a 5 kb file named KoboRoot.tgz
When updating to koreader-kobo-arm-kobo-linux-gnueabihf-v2015.11-1735 I tried to follow the instructions and install the legacy FM
https://github.com/baskerville/fmon in combination with the new icon, but since there was no tgz launcher file and no installation instructions a newbie could understand, I returned to the old 5 kb FM KoboRoot.tgz, the old icon, the launcher from v2015.11-1654 (which wasn't included in the 1735 zip). Now it works as usual. I'm still on firmware kobo-update-3.19.5761 since a further firmware update messed up my koreader I cannot live without (I know Start Menu is recommended but the instructions were beyond me and I'm used to Nickel - ".hidden" folder names)
