im failing very early on installing the build dependencies, many
packages are not installablelinux@linux-virtual-machine:~$ sudo apt-get build-dep qtbase5-dev [sudo] password for linux: Reading package lists...

Done Package libxcb-glx0-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'libxcb-glx0-dev' has no installation candidateany idea what im doing wrong
background im working on serveral applications under this linux using QtCreator etc. gcc, clang, cmake everything works, so i have no idea what is wrong with my system
long-term goal is a TSAN build of Qt but first i want to get the vanialle build done and tested

The error message shouts it all out:
This may mean that the package is missing, has been obsoleted, or
is only available from another sourceHere it is: https://ubuntu.pkgs.org/22.04/ubuntu-main-amd64/libxcb-glx0-dev_1.14-3ubuntu3_amd64.deb.html

but how to install libxcb-glx0-dev - i've tried to use the apt install as usual

You still seem to be trying to install it from the Ubuntu repo, where it apparently does not exist? All you have done here is repeat the command from earlier which errors, we have already seen that. That is presumably why @Axel-Spoerl gave you a link to download the.debdirectly and install from that? -
i think i've solved it
the first and last from "Downloadable from the Internet" was missing
now also "sudo apt-get build-dep qtbase5-dev" is working as expected@JonB
Normally there is no need to download debs manuallyand yes i did a sudo apt update/upgrade etc. before

@LowLevelM said in Ubuntu 22.04, Qt5.15.x: can't sudo apt install many build dependency packages - how to solve?:

I know this, since I use Ubuntu :) But once in a while you have to fetch a
.deband install from that, if the package is missing from the standard repos. I had to do so recently for some package. I thought that was the case here, but I think you are saying you have found it with some settings. I never use the "Ubuntu Software" updater you show. -

me too :)
found that on https://wiki.qt.io/Building_Qt_5_from_Git
Then you will need to enable the "Source code" option in Software and Updates > Ubuntu Software under the "Downloadable from the Internet" section. This setting can also be found by running software-properties-gtk.but that wasn't enough

You don't need source code repository to install libxcb-glx0-dev. The problem was that "main" repository was disabled for whatever reason.

so the information about adding the source repo on https://wiki.qt.io/Building_Qt_5_from_Git is deprecated? or only not needed for libxcb-glx0-dev?

Not necesserily. All I said is that to install libxcb-glx0-dev you do not need source repos...
