AWS RoboMaker - Sample Application - Hello World - Stuck

Hi Amazonians, I am trying the tutorials in AWS RoboMaker Developer Guide, specifically this part: > **AWS RoboMaker Developer Guide** > Getting Started > Step 3: Configure Environment and Build Applications > Modify and Build Applications > 3. In the **HelloWorld** AWS Cloud9 development environment, choose Resources, then choose **Download samples**, and then select **1. Hello World.** Link: https://docs.aws.amazon.com/robomaker/latest/dg/gs-build.html Half way downloading the samples, the terminal prompted me for a decision: ``` debconf: falling back to frontend: Readline Configuring unattended-upgrades ------------------------------- A new version (/etc/apt/apt.conf.d/50unattended-upgrades.ucftmp) of configuration file /etc/apt/apt.conf.d/50unattended-upgrades is available, but the version installed currently has been locally modified. 1. install the package maintainer&#39;s version 2. keep the local version currently installed 3. show the differences between the versions 4. show a side-by-side difference between the versions 5. show a 3-way difference between available versions 6. do a 3-way merge between available versions 7. start a new shell to examine the situation What do you want to do about modified configuration file 50unattended-upgrades? 1 1 1. 1. 1. install 1. install the package maintainer&#39;s version 2 2. 2. 2. keep 2. keep the local version currently installed ^[[A ^[[B ^[[D^[[C ^C Process exited with code: 0 Pane is dead ``` I have been trying to get through the prompt by typing the numbers, the sentence, up and down, but everything fails. Finally, I ended the process using Ctrl + C. This seems like a very dumb question but I just can&#39;t continue the tutorial. I have been Googling as well but to no avail. Any help or guide from Amazonians would be much appreciated!! Thank you very much!! :)

Cannot select options to "GRUB install devices" prompt

Hi all, I was trying the tutorial in setting up an environment and building applications (https://docs.aws.amazon.com/robomaker/latest/dg/gs-build.html) when I encountered this problem. Specifically, after creating the environment, when I tried to download the &#39;Hello World&#39; sample, the following showed up after a while: ``` The GRUB boot loader was previously installed to a disk that is no longer present, or whose unique identifier has changed for some reason. It is important to make sure that the installed GRUB core image stays in sync with GRUB modules and grub.cfg. Please check again to make sure that GRUB is written to the appropriate boot devices. If you&#39;re unsure which drive is designated as boot drive by your BIOS, it is often a good idea to install GRUB to all of them. Note: it is possible to install GRUB to partition boot records as well, and some appropriate partitions are offered here. However, this forces GRUB to use the blocklist mechanism, which makes it less reliable, and therefore is not recommended. 1. /dev/nvme0n1 (51539 MB; ???) 3. none of the above 2. - /dev/nvme0n1p1 (51538 MB; /) (Enter the items you want to select, separated by spaces.) GRUB install devices: ``` Nothing I typed worked; all it does is go into a new line after I press the ENTER key every time without any sort of response. Things I&#39;ve tried: &#39;1&#39;, then ENTER key &#39;1. /dev/nvme0n1&#39;, then ENTER key &#39;1.&#39;, then ENTER key &#39;1 2&#39;, then ENTER key &#39;1. /dev/nvme0n1 (51539 MB; ???)&#39;, then ENTER key Does anyone else have this problem / encountered this? This sounds like a ridiculously simple problem to solve, but I can&#39;t seem to find out how.
