Hi,
I ran upon the same error message while installing ArcGIS 10 license manager on Ubuntu 10.04 (I had no problem with 9.3 version on Ubuntu). I realise this post is a bit old, but who knows, it might be of use to someone else.
Here's what I did, but it's a bit risky, please make backups if you want to try it :
- downloaded binutils 2.11.93.02 RPM
- used alien to make DEB from RPM
- uninstalled current version of binutils (dependencies had to be uninstalled too).
- installed instead binutils 2.11.93.02
- proceeded with license manager installation : it went fine, everything ok, ArcGIS working on windows computer with my ubuntu server
- rebooted, keeping my fingers crossed that my server WOULD reboot
- gave a huge sigh of relief
- reinstalled current version of binutils, just out of curiosity
- it still works!!
So I guess you could skip the reboot stage.
Hope this helps...
Official Ubuntu support would be great though! Would ESRI consider it in the future?
