+==== Troubleshooting ====
+=== Locale error ===
+If you experience the error below after starting a particular shell container, then it is likely due to your current locale not being supported in this particular container's shell.
+<code bash>
+[traine@r00n45 ~]$ vpkg_require singularity
+Adding package `singularity/2.5.1` to your environment
+[traine@r00n45 ~]$ singularity shell tensorflow.simg
+Singularity: Invoking an interactive shell within container...
+Singularity tensorflow.simg:~> tensorboard --help
+Traceback (most recent call last):
+  File "/usr/local/bin/tensorboard", line 11, in <module>
+    sys.exit(run_main())
+  File "/usr/local/lib/python2.7/dist-packages/tensorboard/main.py", line 48, in run_main
+    program.setup_environment()
+  File "/usr/local/lib/python2.7/dist-packages/tensorboard/program.py", line 57, in setup_environment
+    util.setup_logging()
+  File "/usr/local/lib/python2.7/dist-packages/tensorboard/util.py", line 50, in setup_logging
+    locale.setlocale(locale.LC_ALL, '')
+  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
+    return _setlocale(category, locale)
+locale.Error: unsupported locale setting
+</code>
+Once you start the container shell, check which locale's are supported by using the ''locale -a'' command:
+<code bash>
+Singularity tensorflow.simg:~> locale -a
+locale: Cannot set LC_CTYPE to default locale: No such file or directory
+locale: Cannot set LC_MESSAGES to default locale: No such file or directory
+locale: Cannot set LC_COLLATE to default locale: No such file or directory
+C
+C.UTF-8
+POSIX
+</code>
+Of course in this particular case, the locale setting for account ''traine'' is defined as ''en_US.UTF-8'' which is not supported in this shell.  To fix the situation, simply set the ''LANG'' locale to one that is supported before starting the container shell.
+<code bash>
+[traine@r00n45 ~]$ vpkg_require singularity
+Adding package `singularity/2.5.1` to your environment
+[tainne@r00n45 ~]$ LANG=C.UTF-8 singularity shell tensorflow.simg
