OK that is the basic scenario (equivalent to aptitude update && aptitude
upgrade) that I usually use to upgrade.

Actually the diversion issue was fixed in  3.8+dfsg1-3.

Yes they should be identical as the issue was fixed in -7.
However from you log you appear to upgrade from -6 to -7. I think this happens
because somehow, you installed a broken version (-1 or -2) and that prevented
the right creation of diversions. So each time you upgrade it will give this
error, until you purge or force installe (which you did both below).

Yes, I think now your system will no more complain as the install --force-all
forced fix of the diversion.

Installing 3.8 does not uninstall 3.6. This is a feature, not a bug.
The command you ran, does not uninstall lcl units, so you need to uninstall them
too.
Fpc was probably installed manually that is why it remains.

For users, we really recommend to install this way (aptitude install lazarus
fpc) which corresponds to (aptitude then /lazarus i /fpc i g)

You are probably missing a package (which means a missing dependency on our
side)
I'll try to find that dependency, but if you can send me the list of installed
lazarus and lcl packages it could help me.
something like aptitude search 'lazarus|^lcl-'

I consider this the only remaining issue in this bug report.
Is that OK for you?
