Public bug reported:

Binary package hint: dar

There seems to be some mismatch between dar (and dar-static) 2.3.9 and
glibc, as get the output shown below. When I do a full backup (sudo dar
-c $OUTDIR/$dir -z -R /$dir -s 2G), there is no problem, but when I
subsequently attempt at a differential backup (sudo dar -A
$OUTDIR/$latest -R /$dir -c $OUTDIR/${dir}_diff`date +'%F'`), I get the
error message shown below. I'm running Ubuntu 9.10. I find nothing
(except documentation) in Synaptic when searching for 'glibc', but libc
is version 2.10.1-0.

Regards,
