17.3.5. Are You Seeing Python Errors?

During some upgrades or installations of Red Hat Enterprise Linux, the installation program (also known as anaconda) may fail with a Python or traceback error. This error may occur after the selection of individual packages or while trying to save the upgrade log in the /tmp/directory. The error may look similar to:

Traceback (innermost last):
File "/var/tmp/anaconda-7.1//usr/lib/anaconda/iw/progress_gui.py", line 20, in run
rc = self.todo.doInstall ()    
File "/var/tmp/anaconda-7.1//usr/lib/anaconda/todo.py", line 1468, in doInstall 
self.fstab.savePartitions ()    
File "fstab.py", line 221, in savePartitions      
sys.exit(0)  
SystemExit: 0   
Local variables in innermost frame:  
self: <fstab.GuiFstab instance at 8446fe0>  
sys: <module 'sys' (built-in)>  
ToDo object:  (itodo  ToDo  p1  (dp2  S'method'  p3  (iimage  CdromInstallMethod  
p4  (dp5  S'progressWindow'  p6   <failed>

This error occurs in some systems where links to /tmp/ are symbolic to other locations or have been changed since creation. These symbolic or changed links are invalid during the installation process, so the installation program cannot write information and fails.

If you experience such an error, first try to download any available updates for anaconda. Updates for anaconda and instructions for using them can be found at:
