According to rmadison, the only automake1.10 package is the source:
$ rmadison -u ubuntu automake1.10
automake1.10 | 1:1.10.1-2 | hardy | source
automake1.10 | 1:1.10.1-3 | intrepid | source
automake1.10 | 1:1.10.2-0ubuntu3 |jaunty | source
automake1.10 |
Ubuntu's automake1.10 source has not yet been altered to produce an
automake1.10 binary. Its old automake binary was clobbered by
automake1.11, so automake1.10 is no longer Provided by automake. This is
likely a bug in the Ubuntu automake1.10 source package.
