Update manager aborts on eclipse-platform-gcj when updating from Dapper to Edgy

Right, the term.log has all the gooey details on eclipse-platform-gcj

the gcj packages are installed and configured, before libgcj7-0 is even installed; currently I cannot see anything about the package beeing tried to install.

What do you want more info about?

I had Eclipse with -gcj packages installed on Dapper, ran update-manager -c -d and then this happened.

Thanks for your additional information.

The logs should be fine, no more info needed. I was unable to reproduce this problem on a i386 dapper->edgy upgrade but maybe I had a slightly different set of eclispse packages installed.

Not sure what's going on here, but it can't be fixed in Edgy now; please investigate and decide whether it needs the "later" milestone I've added for early work in Feisty.

Matthias, please have a look at this for Herd 1

This is probably caused by a bug in dh_nativejava where it adds the following snippet to postrm:

if [ -x "/usr/bin/rebuild-gcj-db" ]; then
        /usr/bin/rebuild-gcj-db
fi

rebuild-gcj-db can exist on the file system due to the package being unpacked (but not configured) without it being usable, so dh_nativejava should probably have an || true there.

doko, can you please get this fixed?

fixed in java-gcj-compat_1.0.65-8ubuntu2

reuploaded eclipse 3.2.1-2ubuntu1
