Packet manager problems after upgrade

[name7891]

Hello Community,

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.

I also asked this question in askUbuntu and received an answer. My problem is that the answer is cryptic to me and I would like to ask for your help to really understand what to do. The answer is as follows:

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




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 packages for which this will be necessary? (I think how to ppa-purge I will easily find on the internet).

Thank you very much in advance for your help.

You could try and get libvulkan-dev from a PPA so that it can handle libvulkan1 version 1.1.114.0-1~gpu18.04.1, but that may lead to dependency hell. And I don't know what's in that PPA. If you don't really need libvulkan1 version 1.1.114, but version 1.1.101 is also acceptable, I suggest you downgrade libvulkan1 to the version from the official repositories. Use whatever is your favourite interface to package management and force the version from the official repos. Disable the PPA.

Then you should upgrade to 19.10 as 19.04 is EOL

That isn't true. 19.04 will be supported until some day in January.

I suggest a clean install of 19.10 without PPA's or other additions. It will give you 1.1.114 and guarantee that all packages are in sync.
