"I don't see a clear reproduction" - OK, but what does that mean? Can we work on getting a *clear reproduction*? Samba keeps segfaulting here and it is very reproducible, so if the core dumps are not enough, then I suppose I could provide a gdb dump? -- You received this bug notification because

Thanks for the updates, unfortunately I don't see a clear reproduction and I don't think progress will be made on fixing this until that exists. I'll set this to incomplete for now, set back to New if there is more information to make this actionable. ** Changed in: samba (Ubuntu) Status:

pdbedit -L yields no results. So I purged samba once again (apt purge samba samba-common) and reinstalled, but there'are still no users in the DB. Also, purging packages removes the /var/lib/samba and its contents, so it can't be the corrupted data there at fault. -- You received this bug

Ok, since you purged and reinstalled, let's try to get a fresh crash file. First, remove any samba related crash files from /var/crash/*. Unless you have other crashes in that directory for other apps that you plan to file bugs for, I would even remove all content from /var/crash. Then trigger

Hi Andreas, These interfaces *do* exist and samba worked before with the same setting just fine. I do, however, use the udev rules to rename the generic interface names to 'lan' and 'wlan'. But as I said, samba worked before in this setup. I just purged the samba including samba-commmon package

[Bug 1738119] Re: Samba crashes during startup

I believe your interfaces setting in smb.conf is incorrect: interfaces = lan wlan That tells the service to bind to an interface named "lan" and an interface named "wlan". If these interfaces don't exist, samba will fail to start. It shouldn't segfault, of course, but it will definitely
