How to install Nuget on Amazon Linux - amazon-ec2

Question

I'm trying to get Nuget installed on an Amazon Linux image. My goal is to do some research with the AWS .NET SDK that has some support for .netcore.
I have tried three (On a fresh instance each attempt) primary installation methods.
1 - Install .netcore then compile Nuget from source.
I installed .netcore successfully following the directions here although I modified (my changes are in bold) how the updates to the path are persisted by using these steps:
# sudo yum install libunwind libicu -y
# curl -sSL -o dotnet.tar.gz https://go.microsoft.com/fwlink/?LinkID=835019
# sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet
**# echo 'pathmunge /opt/dotnet' > /etc/profile.d/dotnetcore.sh**
**# chmod +x /etc/profile.d/dotnetcore.sh**
**# . /etc/profile**
I then cloned the Nuget code from here https://github.com/NuGet/NuGet.Client and ran build.sh which completed successfully but did not create an artifacts subdirectory with a Nuget executable. This method was only meant to install the NuGet CLI - not the package manager - but installed neither. Only the CLI is supported on Linux according to this site: https://docs.nuget.org/ndocs/guides/install-nuget ("The NuGet CLI is the command-line utility that works on Windows, Mac OS X, and Linux and supports all NuGet capabilities.")
2 - Install Mono and run "yum install nuget"
I successfully installed Mono by executing these steps:
# sudo yum -y install cmake bison gettext glib2 freetype fontconfig libpng
libpng-devel libX11 libX11-devel glib2-devel libexif glibc-devel
urw-fonts java
unzip gcc gcc-c++ automake autoconf libtool make bzip2 wget
# cd /usr/local/src
# sudo wget http://download.mono-project.com/sources/mono/mono-4.8.0.382.tar.bz2
# sudo tar jxf mono-4.8.0.382.tar.bz2
# cd mono-4.8.0
# sudo ./configure --prefix=/opt/mono
# sudo make
# sudo make install
After mono was installed and tested I added some repos with the following commands:
# rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
# yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
# yum-config-manager --add-repo http://download.mono-project.com/repo/centos-nightly/
I received a dependency error when I ran the yum install nuget command, the results:
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main/latest
amzn-updates/latest

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
I tried re-installing with the --skip-broken command but nuget did not install.
At this point I tried to manually update the Libpng packages by building the latest Libpng code from here http://www.libpng.org/pub/png/libpng.html
At this point I am begining to reach the limit of my linux abilities. I was able to successfull build the libpng with
./configure
make
make install
But I am not certain the libraries where updated OR if I just now have TWO versions of libpng. I am not certain how to see which version is being used by Yum.
3 - Install .net core then run "yum install nuget"
I get the exact same error that I received in attempt #2.

Answer 1

Just ran on the same issue, was able to resolve it by installing manually libpng. If you are on the same environment now, at first delete current libpng.
yum remove libpng
After that you can do this in the way:
mkdir -p /tmp/dependencies
cd /tmp/dependencies
wget https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/Packages/l/libpng15-1.5.28-2.fc26.x86_64.rpm
yum install -y libpng15-1.5.28-2.fc26.x86_64.rpm
yum install -y yum-utils
rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
yum clean all
yum makecache
yum install -y mono-complete nuget
cd
rm -rf /tmp/dependencies
NOTE: Make sure also you have enabled EPEL on machine.
Also could be that you didn't succeed because you didn't clear yum cache dependency.
