** Description changed:
- This morning I got an update notification saying that new libc6,
- libc6-dev, and libc6-i686 packages were available for upgrade. I
- clicked OK to upgrade them. The upgrade of libc6-dev failed; the
- details from update-manager show:
+ The preinst script in libc6 (and variants) contains a sanity check which
+ is designed to locate improperly-installed components of glibc. Upon
+ finding such a component, it aborts installation of the package.
+
+ The system is not harmed in any way. The only negative effect is a
+ failure to install updates.
+
+ There are two problems related to this check:
+
+ 1. The test contains a bug causing it to be triggered by an unrelated
+ (valid) library provided by the libpthread20 package.
+
+ 2. Some users have reported occurrences of /usr/lib/libdl.so.2 and
+ /usr/lib/libc.so.6. These files are NOT provided by any Ubuntu package
+ and their origin is as yet unknown.
+
+ For example:

please remove that copy of the C library and try again.
