libpulse-dev installation problem

Bram

There seems to be an issue with libpulse-dev in Ubuntu 21.10 because if I want to install libsdl2-dev on a fully up-to-date system, I get:

The following packages have unmet dependencies:

libpulse-dev : Depends: libpulse0 (= 1:15.0+dfsg1-1ubuntu2) but 1:15.0+dfsg1-1ubuntu2.1 is to be installed

How do I solve this?

This is on a fresh 64b ubuntu21.10 install.

UPDATE

# apt-cache policy libpulse-dev
libpulse-dev:
  Installed: (none)
  Candidate: 1:15.0+dfsg1-1ubuntu2
  Version table:
     1:15.0+dfsg1-1ubuntu2.2 1 (phased 20%)

     1:15.0+dfsg1-1ubuntu2 500
        500 http://ca.archive.ubuntu.com/ubuntu impish/main amd64 Packages

Ubuntu version, kernel, and architecture:

root@gamer2:/# cat /etc/issue
Ubuntu 21.10 \n \l

root@gamer2:/# uname -a

UPDATE 2

It seems to get libpulse0 from impish, but libpulse-dev from impish-updates, but why?

root@gamer2:/# apt-cache policy libpulse0
libpulse0:
  Installed: 1:15.0+dfsg1-1ubuntu2.1
  Candidate: 1:15.0+dfsg1-1ubuntu2.1

libpulse0 is already the newest version (1:15.0+dfsg1-1ubuntu2.1).
libpulse0 set to manually installed.

UPDATE 3

This PC has no non-default repositories, nor ever had any non-default repositories configured.

There are no holds:

$ apt-mark showhold

I would check your system is fully-updated & software lists are updated; as the *depends* rules you provided don't match a fully upgraded *impish* (21.10) install. See https://packages.ubuntu.com/impish-updates/libpulse-dev or `= 1:15.0+dfsg1-1ubuntu2.2` , ie. start with basics; `sudo apt update` to update software lists, messages clean without errors/warnings, no missing lines etc...

@guiverc it is fully updated, the grep on hold returns nothing.

Please provide `apt-cache policy libpulse-dev` but you didn't provide architecture (64bits is vague; which 64-bit architecture) as package version can vary on architecture I note in CLI queries for *impish*.

@guiverc thanks! See update. Why does the dev want a very specific version? Did libpulse and libpulse-dev get out of sync, where one got a revision bump, and one did not? (In the repo.) I have no non-ubuntu entries in my apt sources.

I'm assuming this is clear; but do you have any holds? (does anything show if you `apt-mark showhold`). The `apt-cache policy` shows the newer package is found & available (with a **phased 20%**) but sorry I've not taken enough notice of phasing (Ubuntu Community Hub has some workarounds if that's the issue; it came in with 21.04)

What does it mean if `apt-cache policy` marks a package with `***`?

The '***' tells you that is the package your system is using, has installed.

"(phased 20%)"

see https://wiki.ubuntu.com/PhasedUpdates https://wiki.ubuntu.com/ErrorTracker/PhasedUpdates

You can wait until the phasing period is over (currently on 50%) or install the package providing the version numbers:

Either

sudo apt install libpulse-dev=1:15.0+dfsg1-1ubuntu2 libpulse0=1:15.0+dfsg1-1ubuntu2 libpulse-mainloop-glib0=1:15.0+dfsg1-1ubuntu2

or

sudo apt install libpulse-dev=1:15.0+dfsg1-1ubuntu2.2 libpulse0=1:15.0+dfsg1-1ubuntu2.2 libpulse-mainloop-glib0=1:15.0+dfsg1-1ubuntu2.2

This seems to be a specific case that may deserve a bug report on Launchpad see also https://answers.launchpad.net/ubuntu/+source/pulseaudio/+question/699828

I normally use apt, but in such a case, after a brief internet search I would try "sudo aptitude ...". For this libpulse issue, aptitude worked.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
