Hi,

Im using Ubuntu 20.04 with ARM64 on amazon AWS platform to host a shiny app. I couldn't install Shiny server directly using the pre-built installers. It gave me this error

>sudo gdebi shiny-server-1.5.16.958-amd64.deb
Reading package lists... Done
Building dependency tree        
Reading state information... Done
Reading state information... Done
This package is uninstallable
Dependency is not satisfiable: libc6 (>= 2.7)

So i tried to install it from the source and ended up getting this error

(cd .. && ./bin/npm install)
./bin/npm: 4: exec: ./bin/../ext/node/bin/node: Exec format error

I followed the discussion in #347 and here and tried both

RUN sed -i '8s/.*/NODE_SHA256=abef7d431d6d0e067fe5797d4fe44039a5577f01ed9e40d7a3496cbb22502f55/' shiny-server/external/node/install-node.sh
RUN sed -i 's/linux-x64.tar.xz/linux-armv7l.tar.xz/' /shiny-server/external/node/install-node.sh

and

sed -i '8s/.*/NODE_SHA256=7a2bb6e37615fa45926ac0ad4e5ecda4a98e2956e468dedc337117bfbae0ac68/' ../external/node/install-node.sh
sed -i 's/linux-x64.tar.xz/linux-armv7l.tar.xz/' ../external/node/install-node.sh

and got this error

So i figured the SHA checksums here were outdated and i'd to use the ones here. Edited the install-node.sh file and changed download link and then got checksum failed.

Checksum failed!

Running out of ways to get this to work now. Any ideas how to solve this ?

Thanks

I think I figured out what the problem is. The default nvm was set to 12.20.0 and the SHA checksum was for 12.20.1. So this is what I did. I followed the instructions here to lock the project's node version. Edited the .nvmrc file to the right node version (in my case 12.20.1) and then edited the ../external/node/install-node.sh script to use the right SHA256 from here by giving 

NODE_SHA256=3c1dff2a7070214fa3947f8b7331c592e2d7c7347693da927b56cfd51ed70917
local NODE_URL="https://nodejs.org/dist/${NODE_VERSION}/${NODE_FILENAME}"

This fixed the issue for me
