After doing a dist-upgrade, I got this error:

vitimiti@vitimiti-X200MA:~$ sudo dpkg --configure -a

I'm sorry that it's in Spanish, I don't know how to make it output in English, but the problem itself is icedtea-netx:amd64 not being able to configure itself, making the other two packages fail, too.

Now some information about the system:

vitimiti@vitimiti-X200MA:~$ uname -a
Linux vitimiti-X200MA 4.4.0-4-generic #19-Ubuntu SMP Fri Feb 5 17:39:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

vitimiti@vitimiti-X200MA:~$

I saw there's another related bug with this package, in version 1.5.1-ubuntu1, bug number is #1363785 I guess it has to do with something similar that might have happened to that version of the package, but I'm not adding it there since this is version 1.6.2-1ubuntu1.

I will add any information needed without problems, but I don't know what else might be needed for now, so if you need it, ask for it.

Status changed to 'Confirmed' because the bug affects multiple users.

I haven't noticed anything out of the ordinary when this appeared. It almost appears as if this affects fresh installs, which mine is. I had to reinstall due to kernel 4.4 not installing correctly. It also seems interesting that I too have Spanish set as the main language, if that even matters...

I have upgraded the system after some time (I had to retain some upgrades due to Ubuntu SDK being incompatible with some new packages for some time) and the problem has disappeared. I thought I should report so.
