Upgrading AutoSys from 11.3.6 SP2 to 11.3.6 SP7, it fails with the following error:
/opt/CA/WorkloadAutomationAE/lib/libcurl.so.4 is not a regular file
$AUTOSYS/lib/libcurl.so.4 (default '/opt/CA/WorkloadAutomationAE/lib/libcurl.so.4') had been changed to a softlink pointing to '/usr/bin/libcurl.so.4' .
The fact that it was a softlink and not a regular file causes the error during installation.
This can easily be overcome by copying over your existing /usr/lib/libcurl.so.4.x.x file as $AUTOSYS/lib/libcurl.so.4 :
cp /usr/lib/libcurl.so.4.x.x $AUTOSYS/lib/libcurl.so.4
