I get this error when my migration gets down to re-creating mail and FTP users.
Any ideas?

I think we need more details.
What are you migrating from and to? Was the relevant software on the old server up to date?

I don’t think there’s anything special about the setups. I think it’s the mail aliases that are causing an issue. I transfered a server without them and there were no problems and the ones that error out have their users on the remote site but not the aliases.
I’m confused by the error, though, as feature-ssl.pl is not involved in mail aliases or FTP users.
Is there any more informative logging I can do?
This server only has the main user and a bunch of aliases. It fails the same for servers that have users and aliases though

Try making a domain backup on the original server, copying the resulting file over to the new one, and restore the domain on the new server…preferably on the command line. I don’t know where to start troubleshooting this, and maybe doing the restore on the command line will provide more clues about what’s going wrong.
LIne 1418 is looking for the servers private key. Strange because the path to ssl.key is the same on the remote server. Same username.
I get the same error when manually transferring the file and restoring it on the remote host.
If I do the restore in the GUI and de-select mail and FTP users I don’t get an error.
There were some changes in the backup code recently around the ssl files, and a bug related to ssl.ca restoration. Maybe this is related to that somehow.
@Ilia have you seen this? Any idea what’s happening here?
With some LLM help I replaced
my $lref = &read_file_lines($key, 1);
With
if (!$key) {
&error("Empty SSL key path (undef or empty)");
}
if (!-e $key) {
&error("SSL key does not exist: $key");
}
if (!-r $key) {
&error("SSL key not readable (perms/ownership): $key");
}
my $lref;
my $ok = eval {
$lref = &read_file_lines($key, 1);
1;
};
if (!$ok) {
# If read_file_lines() throws, this will show the file path in the UI
&error("Failed to read SSL key with read_file_lines: $key");
}
And now I get
Empty SSL key path (undef or empty)
It’s a DKIM error.
Probably because I have a global DKIM key on the sending server and nothing on the receiving in Virtualmin
It’s because I set up opendkim, openarc and opendmarc on the receiving server so it mirrored the sending but I should have enabled DKIM in Virtualmin first before I manually tweaked everything.
It’s a bug that restoring a backup fails because of that, though. Backups and restores should always been really reliable and resilient even if something is different on the new system.
I’ll ask @Jamie to take a look.
@Joe, I’m not sure offhand what’s causing it, but if I had a backup file and have it failing on my system, I could take a closer look and likely fix it—unless Jamie gets to it first.
Right now, though, I’m focused on wrapping up reworking the UI and trying not to get sidetracked, since switching between different kinds of work slows things down quite a bit.
@Pook, can you send it as a private message like @staff and attach a backup file for download? Try to find the smallest domain; we just need to see the problem.
Taking a look at this now ..
I checked in a fix that should solve this here : Don't get type of key that doesn't exist · virtualmin/virtualmin-gpl@d8e0b52 · GitHub
Isn’t this a workaround for the actual issue? Where did the key go?
I’m sure I caused it by not having DKIM enabled in virtualmin but setting opendkim, openarc and opendmarc up so everything worked but wasn’t enabled in the GUI.
I added this in to track it down;
if (!$key) {
require Carp;
&error("Empty SSL key passed to get_ssl_key_type()\n".
Carp::longmess("call stack:"));
}

Seems like somehow Virtualmin thinks DKIM is setup, but cannot find any key in the config?
Is there a dkim_enabled line in your /etc/webmin/virtual-server/config file?
