[Samba] samba-ad-dc from debian backports fails to start with /usr/sbin/samba missing

I'm curious, I really am, - why aren't you seeing the NEWS entries I've written. Debian packages has NEWS mechanism - important information which is supposed to be presented to the user on package upgrades. apt-listchanges package is responsible for this -- it is a part of standard install, with Priority: standard, so it is initially present on any debian system installed the regular way. By default, NEWS entries, if any, are displayed while upgrading a package, apt waits the user to acknowledge the reading. What prevents you and others from seeing these entries? I had another way to do this transition (moving some files from main samba package to samba-ad-dc package). For example, it's possible to make samba Recommends: samba-ad-dc, so samba-ad-dc package will be installed most of the time (unless the user disabled installing recommended packages, which is not recommended). But I don't want to do that, because samba-ad-dc has additional dependencies not needed by samba. So I went this way, adding the fine docs to samba.NEWS file (/usr/share/doc/samba/NEWS.gz), in a hope the user will read this info. Apparently they aren't aware of that. (When upgrading from bookworm to trixie, there will be release notes document, where we'll mention this change in samba, - so this one will have a bit more chances to be seen, at least).

[Samba] samba-ad-dc from debian backports fails to start with /usr/sbin/samba missing
Hello mjt, I can only speak for myself: For bigger upgrades (e. g. samba 4.19 -> 4.20) Im manually updating a few servers and check if everything works. For smaller updates (e. g. 4.20.1 -> 4.20.2) Im using saltstack to automate updating the servers. It suppresses these messages and this is fine in 99% of all cases because a minor update is not supposed to change much (e. g. split a package). Funnily enough our DCs kept running after updating to 4.20.2 WITHOUT the samba-ad-dc package. Dont know why it worked for us and not for everybody else. Regards, Matthias.

[Samba] samba-ad-dc from debian backports fails to start with /usr/sbin/samba missing
Michael, Maybe I can answer why so few are seeing the NEWS entries you created.? I checked all my Debian systems, and only one has apt-listchanges installed.? The systems were all done via a netinstall .iso.? I don't recall installing apt-listchanges on the one system, but I must have somewhere in time.? So, for any other individuals who installed the OS as I did, there is no NEWS mechanism by default. Fortunately, I had read your changelog explanation on the list and installed the samba-ad-dc package after running the upgrade.? The one surprise that I got was that I had to reboot the upgraded DC before its processes would start.? Member servers and standalones successfully upgraded without a reboot.

I am a hobby user. I have a dozen or so headless Debian VMs running in my home network. Because the time to do the repetitive work of installing updates for each VM became quite significant, I am using unattended-upgrades package to automate installing updates. After having been bitten by some updates, ending up with non-functional VMs in some rare cases, I limited the unattended upgrades to debian-security, and this setup has been working generally fine for quite some time. Unattended-upgrades sends e-mails from each VM after it has been doing something. I am not quite sure if NEWS entries would be shown in such an e-mail, but I am guessing that this is the case, as it is recommended to install apt-listchanges together with unattended-upgrades. I recently deleted my e-mail trashcan, so I can't check my e-mails for these NEWS entries. I will definitely pay attention in the future. As the number of system e-mails with information on installed updated is quite high, I tend to just check which updates have been installed (in the first couple of lines in the e-mail) and skip the rest of the mail with dpkg logs and other information. So it could very well be that the NEWS entries have been sent to me via e-mail, and I didn't read the whole mail and thus didn't see the NEWS entry. If the NEWS entry had been part of the automated e-mail from unattended-upgrades, it could have helped to add a Warning or something in the e-mail header and/or the first lines to check for NEWS entries, that would have increased the likelihood of me noticing it. On top of that, I tend to watch the Samba mailing list, although I don't read every thread. The ones from you, Michael, I usually read, so it is quite likely that I have read your caveat on the upcoming changes, but I wasn't aware of that when sending my question to the list. Probably I simply forgot that fact. I did an internet search on my issue including the error message. I didn't find anything useful. This seems to corroborate my impression that mailing list content (also from other mailing lists, not only Samba) doesn't seem to be indexed/referenced very well by the google search engine. I also guess that my case is similar to the one from Matthias K?hne in this thread, and I installed the update, but didn't restart the VM, so I didn't notice the change right away. I think that my last reboot before samba didn't work anymore had been a while ago. I checked dpkg and unattended-upgrades logs, but didn't find anything helpful. Hope this helps a bit. Thank you (and the whole Samba team, of course) for your work! Paul
