Installation tips

To share some tips for some annoying errors when installing or running some programs.......

NOTE: guidelines here are based on M1.

So far, Multipass seems to be the best (and perhaps only) option for running Ubuntu 18.04 on M1

Multipass

• GUI Dekstop Environment

  Use Microsoft Remote Desktop app
  sudo apt update
sudo apt upgrade
sudo apt install ubuntu-desktop xrdp

  After installation, you need to set a password.

  Then when you run the app,
  
  click '+' and 'Add PC'

  Copy the IP address (on multipass terminal) or IPv4 (if you run multipass info <'name of the linux'>)

  

  and paste it in the PC name of the 'Add PC' screen.

  

  A new PC is now added.

UTM

• Ubuntu 18.04

  Problem: "Stuck in black screen with flashing cursor when booting to install Ubuntu"

  Solution: Change the display setting from "Graphics interface" to "Console interface" when running installation codes.

• Ubuntu 20.04

  Error: "EFI stub: Exiting boot services and installing virtual address map…"

  Cause: Sometimes UTM becomes frozen, and when you forcibly shut down the virtual machine, this error will occur when rebooting it.

  Solution:
  1) In the VM setting, switch display setting from full graphics to console mode.
  2) Restart the VM and go into “Ubuntu”
  3) Run fsck -y /dev/mapper/ubuntu--vg-root (Read the code, and if it’s fsck.ext4, type it instead of “fsck”. If the directory is a bit different from the code, use the one written in the code)
  4) Run exit. Close the VM and switch display setting back to full graphics.

MoveIt 2 (Foxy)

1. Problem: "Cannot locate rosdep definition for [python-lxml] and [python3]"

• When running rosdep install -r --from-paths . --ignore-src --rosdistro $ROS_DISTRO -y,
  error code is ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: moveit_kinematics: Cannot locate rosdep definition for [python-lxml] moveit_ros_planning_interface: Cannot locate rosdep definition for [python3]

• Solution:

  1. Run echo $ROS_DISTRO to make sure ROS_DISTRO environment variable is set
  2. Run rosdep resolve python-lxml -v. But ERROR: no rosdep rule for 'python-lxml'
  3. Run sudo apt update, sudo apt dist-upgrade.

2. Problem: "fatal error: linux/errno.h: No such file or directory"

• When running colcon build --mixin release
  error code is /usr/include/aarch64-linux-gnu/bits/errno.h:26:11

• Solution:

  1. install the missing file linux.errno.h by installing “linux-libc-dev-arm64-cross” package by running sudo apt-get install linux-libc-dev-arm64-cross
  • Note to check which package you’re missing (https://packages.debian.org/search?searchon=contents&keywords=errno.h&mode=exactfilename&suite=bullseye&arch=any)
