# libjpeg.so.62: Cannot Open Shared Object File: No Such File or Directory¶

If the error message

ImportError: libjpeg.so.62: cannot open shared object file: No such file or directory


appears when you try to launch QuantumATK, fix it by running

sudo apt-get install libjpeg62


This error typically appears on Ubuntu version 12.04 and later, where this library is not installed by default, as it was in earlier versions.
