Description Ed Swierk 2006-11-03 05:50:56 UTC

Using Anaconda to upgrade an FC5 system to FC6, it crashes after I click Next in
the final confirmation dialog before installation begins.  This is the only part
of the traceback I could capture:

21:28:50 INFO    : moving (1) to step confirmupgrade

Comment 1 Ed Swierk 2006-11-03 06:10:13 UTC

The crash occurred because I had replaced /etc/mtab with a symlink to /proc/mounts.

Adding os.unlink(anaconda.rootPath + "/etc/mtab") immediately after the "An old
mtab can cause confusion" comment in yuminstall.py would avoid the crash.

Comment 2 Chris Lumens 2007-02-22 21:14:02 UTC

This will be fixed in the next build of anaconda.  Thanks for the report.
