Unable to locate package msodbcsql

I got the same error on Debian GNU/Linux 9.

It turn out to be the failure in apt-get update

# apt-get update
....
N: Is the package apt-transport-https installed?
E: Failed to fetch https://packages.microsoft.com/debian/9/prod/dists/stretch/InRelease

According to the error log, I ran apt-get install apt-transport-https and apt-get update again.

Then I can do the ACCEPT_EULA=Y apt-get install msodbcsql17 successfully

Note: I was in root, if you're not, add sudo, try it. :)

It seems, because, according to that url, right command for Ubuntu is:

sudo ACCEPT_EULA=Y apt-get install msodbcsql17

full script for 16.04:

sudo su 
curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -

#Download appropriate package for the OS version
#Choose only ONE of the following, corresponding to your OS version


#Ubuntu 16.04
curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list


exit
sudo apt-get update
sudo ACCEPT_EULA=Y apt-get install msodbcsql17
# optional: for bcp and sqlcmd
sudo ACCEPT_EULA=Y apt-get install mssql-tools
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc
# optional: for unixODBC development headers
sudo apt-get install unixodbc-dev

Update (13 Apr 18)

Consider to check that Microsoft repository properly registered by running:

sudo apt-get update

As a result you should see a line similar to a "Get:30 http packages.microsoft.com/ .."

My vm example:

Get:29 http://security.ubuntu.com/ubuntu xenial-security/multiverse amd64 Packages [3,208 B]
Get:30 https://packages.microsoft.com/ubuntu/16.04/prod xenial/main amd64 Packages [31.7 kB]
Fetched 12.9 MB in 5s (2,265 kB/s)

After searching, I have found the requested package is located on Microsoft Ubuntu 18.04 repository. To install the package We have to add the repository first and then we have to run following commands.

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
echo "deb [arch=amd64] https://packages.microsoft.com/ubuntu/18.04/prod bionic 
main" | sudo tee /etc/apt/sources.list.d/mssql-release.list
sudo apt update
sudo apt install msodbcsql17

Above command will setup msodbcsql17.

Cheers :)
