 Hello I have an Onion Omega and Arduino dock original from kickstarter times. It has been working as an old project and wanted to update the Arduino code via wireless. it was working fine before, a few months ago, but now I get processing.app.debug.RunnerException

 ... 5 moreI am using - Ubuntu 20.04, with all its latest updated- arduino ide 1.8.13- onion omega board link
 https://github.com/OnionIoT/Onion-Arduino-Boards/raw/master/IDE_Board_Manager/package_onion.io_index.json
 my .ssh/config has
 Host Omega-0B95
 StrictHostKeyChecking no
 User root
 Ciphers 3des-cbc,aes128-ctr,aes256-ctr
 KexAlgorithms +diffie-hellman-group1-sha1
 worst case I can upload the code manually via ssh and updated it via "sh /usr/bin/arduino-dock i2c_liquid_sensor.ino.with_bootloader.hex", but just curious as to why it started failing Any ideas/suggestions would be appreciated? 
 cheers,
 Pasquale

 @Pasquale-Riccio my guess is there is an issue/incompatibility with your ssh saved configuration on your Ubuntu machine, try clearing out ~/.ssh ,
