According to the https://docs.microsoft.com/zh-cn/sql/linux/quickstart-install-connect-ubuntu? website tutorial View=SQL server - ver15
To install command line tools, enter sudo apt - get the install MSSQL - tools unixodbc - dev. :
The following packages have unmet dependency:
MSSQL - tools: rely on: msodbcsql17 (& gt;=17.3.0.0) but it will not be installed
Unixodbc - dev: rely on: unixodbc (=2.3.7)
Rely on: odbcinst1debian2 (=2.3.7) but it will not be installed
E: unable to correct mistakes, because you asked to keep the status quo, some software packages is that they destroyed the dependence of software compartment,


Will be apt to get to the aptitude, input SQLCMD:
SQLCMD: error while loading Shared libraries: libodbc. So. 2: always open a Shared object file: No to the file or directory,

For help, this is what reason!!!!!
