ubuntu 20.04: libnss-winbind:386 should remain

[msaxl]

Ubuntu 20.04 limits the available i386 packages.
There are some applications and its dependencies that are kept in i386.

I think libnss libraries/plugins should be available in both archs since having them only on one arch might be confusing (ex. in wine the %USERNAME% variable could be uid or the username)

since essentially libnss-winbind is compiled only the package is not assembled I think the work maintaining this package is quite low (libwbclient0:i386 already is available)

Hi msaxl,
some background can be found in bug 1858479 [1] which lead to upload [2] dropping the package. Thanks for already bringing it up in discourse [3] btw!

We subscribed Steve Langasek to this bug so he can consider and give you an authoritative answer since he is managing the majority of the i386 removal.

The removal of libnss-winbind was based on the fact that it had not been identified as a package we wanted to keep, and it had additional dependencies that were not also included in the i386 set which made it uninstallable. If there is a reason to keep it (which from the discourse discussion and this bug I agree there is), then we can readd it and seed it so that its dependencies will also be white listed.

I don't immediately see why it was uninstallable before (and therefore removed), but I do see that at minimum we will also need to readd the winbind and samba-common-bin binary packages as well.

I'll go ahead and re-add those in a MR soon, based on what @vorlon said.

[Rafael David Tinoco (rafaeldtinoco)]

$ ls *common-bin*.deb *nss*.deb
libnss-winbind_4.11.1+dfsg-3ubuntu4_i386.deb samba-common-bin_4.11.1+dfsg-3ubuntu4_i386.deb

I'm pushing a MR and referring this bug for reviewing/acceptance.

Related bug:

As python-crypto needed a rebuild to allow libnss-winbind and winbind to be installable (due to its dependencies).
