[ubuntu-18.04] Installation of wine32:i386 broken since last night

[hartwork]

Description
My workflow YAML is installing package wine32:i386 on image ubuntu-18.04 and it worked fine until yesterday, but started failing tonight (error below) and keeps failing when I re-run that job.

PS: Running things outside GitHub Actions with plain Docker like this still works fine todday:

# docker run --rm -it ubuntu:18.04 bash -c 'dpkg --add-architecture i386 && apt-get update && apt-get install --yes --no-install-recommends -V wine32:i386'

Hi @hartwork!
The root cause is that some packages depends on "ppa:ondrej/php" repository, which were removed from the apt list after the image was generated.
Adding it back solves the issue:
sudo apt-add-repository "ppa:ondrej/php" -y

[hartwork]

@miketimofeev I confirm that this workaround works (and that I did find traces of ppa:ondrej/php in previous logs) — thanks a lot! 👍 I'm surprised and shocked and amazed all at the same time. We have zero PHP in libexpat so it would be nice to not need a PHP repository to install wine32 without conflicts. Any chance I will be able to drop that band-aid again in the future?

[miketimofeev]

@hartwork actually we are also surprised by the number of packages that come from the ppa:ondrej/php and agree that it's not obvious at all to add that ppa back when you have no dependencies on PHP.
We're going to revert this PR #3272 and deploy the new image next week.
Sorry for the inconvenience!

@miketimofeev I guess the…

# remove repository after successfull installation
rm -r /etc/apt/sources.list.d/ondrej-ubuntu-php-*

…in #3272 are the problem, maybe not the rest of it. Thanks again for your quick and helpful reaction! 👍 👍

PS: It sounds like the ticket will remain open until then. I will stay subscribed here then and drop the workaround on ticket closing. If that's a misunderstanding on my side, please let me know.

[miketimofeev]

@hartwork yes, please, let's leave the ticket open. I'll update it when the deployment is done.

[hartwork]

@miketimofeev excellent! 👍

For the record, there have been changes apparently (e.g. at ondrej/php/ubuntu on 2021-05-09) and now I am back at regression…

 The following packages have unmet dependencies:
 wine32:i386 : Depends: libwine:i386 (= 3.0-1ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

…despite sudo apt-add-repository "ppa:ondrej/php" -y again today.

[hartwork]

PS: It doesn't seem to happen every time though, maybe there is a stale cache or out-of-sync mirrors behind the CI somewhere 🤷‍♂️

[miketimofeev]

@hartwork we've deployed the new images. I checked wine32 installation — everything works like a charm now.
I'm going to close the issue. Please feel free to contact us if you have any concerns

[hartwork]

Thanks! 👍

I've got the same problem. Seems like the regression is back.
