How to fix "Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError."?

When running InTime in Linux, you encounter an error message containing:

“Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.”

or similar.

This may be due to the fact that the lzma library is not installed / detected properly.

(Ubuntu) Install the lzma library.

[root@host ~]# apt install liblzma-dev
[root@host ~]# cd /lib/x86_64-linux-gnu

Create a symbolic link to the liblzma library file.

[root@host x86_64-linux-gnu]# ln -s liblzma.so.5 liblzma.so.0

(Note: The liblzma library file may be named differently on your system, but the symbolic link must be named liblzma.so.0)

(CentOS/RHEL) Install the lzma library.

[root@host ~]# yum install xz-libs

(SUSE) Install the lzma library.

[root@host ~]# zypper install lzma

Create a symbolic link to the liblzma library file to bin6 folder of InTime installation directory.

[root@host ~]# cd <intime_installation_directory>/bin6
[root@host bin6]$ ln -s /usr/lib64/liblzma.so.5 liblzma.so.0
