Similar issue though naming is fine.

(tried with and without trailing slash on the where path)
No settings is not fine
The rule is The Where equals the filename
e.g. the Where is /data/backup
/data/backup must be data-backup.mount (no trailing slashes)
If you change the unit file on-the-fly you need to reload
# systemctl daemon-reload
In your case
create the failure - it should be
/data/smb/qnap_download

Thx for your fast reply. But I don’t see the failure. As mentioned I had the where path initially without the trailing slash. With same result. I added the first line with cat... (thougH I don’t know what this does as in your guides template it’s not in there). Did a restart of systemctl daemon, too.
My file named data-smb-qnap_download.mount content:
$ cat /etc/systemd/system/data-smb-qnap_download.mount
sample smb share mount unit

“New” error in first line is due to the newly added first cat… line I guess.
Oh wow. I needed to remove the comment in the where line… 
Now the assignment error is still present but it mounts. Commented the first cat… line removes that “yellow error”. But my mount is empty. :-/
cat is a terminal command to list the content of a file - it should not be present in your mount unit
Also remove the comments - text starting with #
Makes sense. As you mention it I remember it. But maybe I’m not the only “beginner”/mainly gui user who is not aware of this?! Copyying it from a template not knowing this.
EDIT: Nvm. It works now =)
Is it possible that mounting this way could delete data ony my NAS???
I’m quite sure not, but that’s the only thing I did and I am sure that there has been files before in that network folder!! 
You are actually the first …
The mount itself will not change anything - only users with access will do that.
And your mount being empty
I did a rm -r earlier on a test mount to /mnt/QNAP-Download. I guess that deleted the files?!
I just wanted to delete the folder - not the (my guess) already mounted content. :-/
So with automount it will not be visible in programs unless they access it? Goal for me is to have this path available so that whenever I need to access it from within a program it is there.
That is correct
That is what the automount does - suffice the network service is available.
The whole idea behind automount is the system does not use resources on boot or hang due to missing network or server issues.
And when/from what does that automount get triggered?
I’ve set up everything now. Started .mount once. Stopped. Started .automount. After this I saw the mount in Dolphin appearing. I then started my application (lbry client) selecting the mount point as the download path. Worked. Did a system restart → lbry doesn’t start anymore; mount appears not inside Dolphin. systemctl status show both .mount/.automount inactive.
It gets triggered by systemd
And for it to work after reboot you will have to enable the automount - named the same way as the mount unit - taking your filename
sudo systemctl enable --now data-smb-qnap_download.automount
Then you can forget about it - systemd will do it’s job in the background
I have completely dropped fstab editing - mount/automount units is much more pleasant to work with.
Did the trick. I did just start it before and thought because I “start an automount file” this will enable the autostart… :-/
Hopefully I will never have to reconfigure this again. I will not remember for sure ^^
Is it normal that now the mount appears/disappears for a split second in Dolphin every ~10 seconds? o.O
It’s a bad practice manually configuring/editing (auto)mount entries, the only thing you’ll need to do is creating a new entry in /etc/fstab with the x-systemd.automount parameter ;and afterwards test it if it mounts correctly.
Every (re)boot the corresponding .automount services will startup automatically by systemd checking your /etc/fstab .
So for the topic starter,
for example in /etc/fstab create an entry like:
//xxxxx/Download /data/smb/qnap_download cifs _netdev,iocharset=utf8,rw,file_mode=0777,dir_mode=0777,user=xxx,password=xxx,nofail,x-systemd.automount,x-systemd.device-timeout=1,timeo=14,x-systemd.idle-timeout=1min 0 0
check if it mounts correctly:
sudo mount /data/smb/qnap_download
to unmount
sudo umount /data/smb/qnap_download
If the mounting woks welll, try to reboot, you will see the .automount service is generated and started by systemd
systemctl list-unit-files |grep automount
Please explain - why this - in your opinion is considered bad practice?
