Dependences error aptitude - blocking upgrade and install

[rgb3000]

Hi!
I have a problem installing o upgrade my Ubuntu 16.04 version

If I give these commands:
sudo apt-get upgrade or
or update or sudo apt-get -f install or dpkg --configure

I obtain these errors



sudo apt-get -f install

So I can't install or upgrade my system, I can't remove or purge packets.

I tried without success this post

https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa

My Pc is a 64bit one: why is there aptitude:i386?
Is it possible that I have installed packages for 32bit? How can I fix it?
Have you got ideas?

Thank you in advance

Welcome.

Before discussing the technical issue I should inform you that this is an English forum so even the terminal output should be in English. Italian is not a problem for me but it will be for many others. The way to produce the output in English is is typing LANG=C then Enter before any other command. This way it will stay in English until you close that terminal window. Please do so when asking for help here.

Now, the technical stuff...
Please confirm you're running standard Ubuntu 16.04. If you're running any other flavor (Kubuntu, Xubuntu, Lubuntu, etc.) be aware they're no longer supported (vanilla Ubuntu LTS has 5 years of support but flavors only 3).
Yes, it's normal to have "i386" packages as well, this isn't the problem. Many software needs 32-bit libraries so it's normal. You may or may not remember at some point adding the i386 architecture. This isn't the cause of unmet dependencies, at first glance.

Please run:

LANG=C
sudo apt update
and post here the complete error messages. Meanwhile if you find errors related to PPAs then go ahead and either remove or edit them accordingly and try again.

Thank you for your support

Meanwhile if you find errors related to PPAs then go ahead and either remove or edit them accordingly and try again

Unfortunately I can't remove nothing due to dependencies stuff

[CelticWarrior]

You can remove the PPA that shouldn't be there.
http://ppa.launchpad.net/mc3man/trusty-media/ubuntu/ has the name suggests, it's for "Trusty" (14.04) only.
It can be easily removed in many ways. Arguably the easiest one is by opening Software & Updates (or Software Properties ?? in 16.04, I don't remember exactly but that release had a different name, not used before or since). Then in the "Other Software" tab you should find the aforementioned PPA, click it, remove.

This is likely not what will solve the APT mess you're in but it's the first step. We'll troubleshoot from there.

[dino99]

I highly suspect some conflict with non genuine source(s) like ppa(s)
What to do:
- disable all your ppa(s) then update (synaptic is the easiest way to do it)
- downgrade these package(s)

then the blocking upgrade should have been gone

[rgb3000]

ok thanks

When reading your logs it seems to me that uninstalling some apps might help. From this:
libdrm-dev:amd64
ppa-purge
aptitude:i386
libdrm2:amd64
libgl1-mesa-glx:amd64
libreoffice-ogltrans
libreoffice-core
libreoffice-calc
python3-uno
libreoffice-gnome
libreoffice-pdfimport
libreoffice-gtk
libreoffice-draw
libreoffice-avmedia-backend-gstreamer
libreoffice-writer
libreoffice-impress
libreoffice-math
libreoffice-base-core You could try to uninstall the complete Libreoffice and uninstall the app aptitude. And then try again. Begin uninstalling the app aptitude. Take it by steps. Of course, as said earlier, still have those PPA's disabled. When all is ok, you can enable the appropriate PPA's again, and reinstall those apps.

Then this:
aptitude:i386 : Depends: libapt-pkg4.12:i386 (>= 0.8.16~exp12ubuntu6) but it is not installable...............

Uninstall aptitude. It causes a lot of problems and it is "386" for some odd reason. It shouldn't be 386. It is not about if an app works or not. It is about if it causes dependency problems when upgrading, in this case.
