'New Firmware' notification causes Mission Planner to crash when using Mono

[j-chen-opteran]

Issue details

When running Mission Planner on Linux using mono MissionPlanner.exe, if the vehicle firmware is not the latest version, Mission Planner crashes as soon as a UDP connection is established.

I am running Copter 4.1.1. After establishing a connection over UDP, I get a popup saying that Copter 4.1.2 is available. As soon as this happens, Mission Planner crashes. This was not an issue when 4.1.1 was the latest firmware version.

Version

Mission Planner 1.3.75 build 1.3.7883.26333 Mono JIT compiler version 6.12.0.122

Platform

[ ] All [ ] AntennaTracker [x] Copter [ ] Plane [ ] Rover [ ] Sub

I have the same issue. Mission planner crashes with notification "New Firmware Update Copter 4.1.3"

[RoboViz]

Same issue, 4.1.5 on copter 4.2.1 current stable version

[Xploror]

Did anyone solve this problem, even Im facing it too

[Jazhi]

I faced the same issue. By the way, the README.md mentioned that Linux requirements include "libmono-winforms4.0-cil" which is not available for Ubuntu 20.04. Not sure if it's related or not.

[TheLoki2020]

I'm getting the same issue. Any news ?

[rtalans]

I'm burnt out looking for an answer to this. Is anyone checking this thread?

I haven't posted my workaround yet as I was hoping this would get fixed instead. But, as that doesn't seem to be happening, here's my workaround:

Because the crash is due to something around checking if there is new firmware available, all you need is to disable mission planners ability to perform this check. I've done this by disabling internet access to mission planner. This does have some downsides though. One is that you can't upgrade the firmware without internet access for some reason.

Using some information from here.

1. Create a new linux user group groupadd no-internet
2. Add your user to the group useradd -g no-internet <your-username>
3. Run command sudo iptables -I OUTPUT 1 -m owner --gid-owner no-internet -j DROP
4. Run mission planner with the command sg no-internet "mono /your-path-to-mission-planner/Missionplanner.exe"
5. (Optional) Create a script / bash alias to run the command, for example my bash_aliases has alias mp='sg no-internet "mono ~/Documents/mission_planner/MissionPlanner.exe"'

If you need to update the firmware on your vehicle then you will need to run mission planner with internet access for some reason. But, as you don't have to connect to the board mission planner won't run the new firmware check, so this isn't an issue.

Alternatively, you could disable internet access to your machine to use mission planner, but this doesn't work well for me as turning internet on and off to use mission planner is a huge nuisance.

This appears to be fixed in version 1.3.79 build 1.3.8375.24878.
