I would like to install "qt5-default" on Ubuntu 19.04

starting with

sudo apt-get install qt5-default

I get "qt5-default : Depends: qtbase5-dev but it is not going to be installed"

on

sudo apt-get install qtbase5-dev

I get "qtbase5-dev : Depends: libvulkan-dev but it is not going to be installed"

on

sudo apt-get install libvulkan-dev

I get "libvulkan-dev : Depends: libvulkan1 (= 1.1.101.0-2) but 1.1.114.0-1~gpu18.04.1 is to be installed"

here I am not sure what to do now

This PC is running with a gtx1080ti for which I installed CUDA so I am not sure how exactly to libvulkan1 (= 1.1.101.0-2) to 1.1.114.0-1~gpu18.04.1 and when I do so if I would break anything. Also I am not sure whether my attempt to solve the problem is correct or not. I am not an experienced Ubuntu user.

    Can you post your /etc/apt/sources.list? I'm concerned that you mentioned installing package(s) on 19.04, but you have 18.04 package references. Nov 29, 2019 at 0:42
  • yeah just upgraded my system (2 hours ago)

    Do you have any bionic repos left over, maybe a PPA that you forgot about? Nov 29, 2019 at 0:46
  • seems not like it (just posted the list)

    OK, sources.list looks good. What about other lists in /etc/apt/sources.list.d? The libvulkan-dev package version you referenced comes from the Ubuntu Graphics PPA; maybe it's still pointing to the bionic files. Nov 29, 2019 at 1:14

You got a higher version of libvulkan1 when on 18.04 from the ppa and didn't use ppa-purge before upgrading. So easiest is to add the ppa back for disco and update to the ppa's libvulkan1 package for 19.04 (& any other installed ppa packages) , then use ppa-purge to downgrade to disco packages. Then you should upgrade to 19.10 as 19.04 is EOL

  • Thank you so far, but could you please explain the steps in more detail, it is a little bit confusing for me at the moment to precisely get what to do and especially how to do it.

  • Or asked in detail: What ppa should I add back for disco and how exactly do I update to the ppa's libvulkan1 package? How do I find other package for which this will be necessary? (I think how to ppa-purge I will easily find on the internet).
