Lazarus 1.2.6 and 1.4 use the same compiler. If you installed 1.2.6
from our sourceforge site, then you only need to update the lazarus
deb. It doesn't hurt to install the fpc debs though. deb is clever
enough to figure it out.
Note: In a few months FPC 3.0 will be released. The following
Lazarus 1.4.x release will use that.

These deb files are not made for parallel installation.

As always: Before installing a new Lazarus version make a backup of your
"~/.lazarus" directory.

Installing the 1.4 deb will replace the old 1.2.6.
You can downgrade by installing the 1.2.6 deb.
When starting the IDE it will give you an "upgrade" or "downgrade"
message. Note that "downgrade" from 1.4 to 1.2.x may loose some
settings.

You can install a second Lazarus version in parallel. Do you want that?
