[Lazarus] Bad quality packages on Ubuntu 12.04

[Kjow]

Hi all,

Trying to install fpc_2.6.0-120728_amd64.deb on Ubuntu 12.04 x64 I get
this warning:

The package doesn't provide a valid Installed-Size control field. See
Debian Policy 5.6.20.

Same thing for:

fpc-src_2.6.0-120728_amd64.deb
and
lazarus_1.0RC1-0_amd64.deb

I grabbed he files here:
http://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%201.0RC1/

I forced the installation with "ignore & install" and they installed.

Not yet tried how Lazarus IDE works on ubuntu 12.04.

Regards,
Kjow
