When the 2.13-6 upgrade failed, I accidently (my fault) lost a file. When I could not find it from where I can moved it (it was there, in fact a symlink I could have remade easily enough but ...) I copied the 2.11 files to get up and running again.

OK, but there very presense stimulated ldconfig or whateve to symlink them and that was fatal!

2.13-6 refused to proceed but with a more cryptic error message

2.13-7 correctly named the offending file.

Unfortunately, simply removing was also fatal. I created an alternative ld-linux symlink and then the upgrade could proceed. Why I say the script should take care of this!

OK, I got rid of the 2.11 files.


I, of course, did not touch the 2.13 ones. There are actually only a few of them but are locally symlinked. There would be three version of these, on /lib, lib/i386-gnu... and /lib/i686/cmov. The ones I checked a all different.


Should the /lib ones be actually be removed? Should their symlinks be first changed to the i386 versions (like others in /lib ... and why is there an i686/cmov if it is not being used?) Hopefully this can be achieved without (temporarily) hosing the system. Another reason I feel the scripts should handle this stuff. All the 2.13 files are legal-dpkg items.


I no longer have /usr/lib/gconv.
