[SOLVED] systemd+wpa_supplicant, but the name of interfaces changes

Hello,
I'm following instructions here for having the wireless connection ready at boot on my machine.
I needed to setup two different daemons since sometimes my wireless interfaces is wlp3s0 and sometimes is wlan0.
When the name of the interface is wlp3s0 everything works fine and I'm correctly given an IP address.
It doesn't happen the same when the name is wlan0.
Here's some output
$ systemctl status [email protected] -l

Check your journal for messages relating to wlan0 and wlp3s0. I think you may find some kind of error message -- maybe having to do with firmware. I've seen thing like that break predicatible device names
If you've just one wlan interface, you could turn off predicable device names and just go with wlan0

I have an iBook on itunes and I am trying to upload a new version of the book. I am following the workflow through iBooks Author and when I fell out all of the infromation for the package on iTunes producer i then hit the deliver button and I get the following error message:

As far as I can tell the file that is being referenced does not meet the criteria axpressed in the erro message and in fact that file has been created by iBooks Author so one would think there shouldnt be an error.

How do i get it back! i bought most of my music on itunes but i just dont have any idea where to go and whjat to do can any help me??
Respond please!

Depending upon what country that you are in (music can't be re-downloaded in all countries) then see if you can redownload your past music purchases (those that are still in the store) via the Purchased link under Quick Links on the right-hand side of the iTunes store home page on your computer's iTunes : re-downloading.
If you are not in a country where music can currently be re-downloaded, then have you not got it on your computer and/or on a backup ? If not then you can try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

That"s part of my problem, I dont get that option.
I get iTunes store and that's about it.
I've thought about "erasing/resetting" all settings but I'm afraid to do it. Or am I
missing something in iTunes?
Help please!

When i add a new contact to my phone, their details are saved in my contact list, but the name doesn't show up when they ring or txt me, how can i change that?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

AirDrop works fine, but the name that comes up on both my mini ipad and iPhone 5 is Selena Gomez. Why? Idk... I checked my phone name in settings and it comes up as MY name. What's going on?

Well, then the only answer is that you are Selena Gomez

Of you're being phished. There are a lot of phishing scams going around right now with bad guys trying to get access to apple ID's.
Anytime you want to verify the info, do not click on any links in the mail, but open up iTUnes on your computer and check things out that way.
If you want to verify if anything is wrong http://www.apple.com/support/appleid/contact/
contact apple on your own and see what they say.

I recently got a message on my screen that says "the name of your computer is already in use on this network. The name has been changed to *

I recently got a message with an exclamation mark stating "your computer name is already in use on this network. The name has been changed to ______"
How did this happen, is it phishing, malware, or did someone hit some button on here to change it. I'm hoping that someone else doesn't have access to everything on my computer now. Help!

Hello RaptorTrish,
Interesting name! You don't say what computer you are using, the OS or the nature of the network, home, office etc. Could you fill in a few details.
You are right to be concerned but there is often a simple explanation.

Should I ok "this computer's local hostname Irma-Mac-mini-local" is already in use on this network. The name has been changed to Irma2 Mac-mini 2-local

Should I ok this message-this computer's local hostname Irma's Mac-mini-local is already in use on this network. The name has been changed to Irma's Mac-mini-2local

Don't think this is a conflict with IP Addresses or computer names
= DHCP hangover when computer renews DHCP lease
There is no actual other computer
It just appears that way when reconnects so creates new -2 computer name
What types of names do you use your computers ?
Whether you name them after quantum particles or the romantic poets...
They will each start to be appended with "-2" then "-3" etc if you auto configure network settings from Airport Router DHCP service and you have this Change computer name issue where pop up window states name is already being used on your LAN
As stated previous post you can reset the computer name in SysPrefs / Sharing / Edit button
And restart Router or renew all DHCP leases (if persists in not allowing original name)
Can now press Edit and reset name of choice
But for Fix see link above

I get this message:This computer's local hostname "x-8.local" is already in use on this network. The name has been changed to "x-9.local" I have turned off sharing and it continues to upgrade name. What is the fix?

I get this message: This computer’s local hostname “x-8.local” is already in use on this network. The name has been changed to “x-9.local” I have turned off sharing and it continues to upgrade name. What is the fix?

Hi, this is a common problem, mostly just irksome though.
It can have many cause, like using more than one Interface for connections, Router temporarily losing x.local & seeing a new connection with x.local already used, insists it must be x-1.local, x-2.local, etc..
What all Sharing do you have enabled?
Some possible fixes...

I know on my previous laptop and website when it was working it should a little progress circle where the little

'Publish to' should be set to FTP server
Site name is the name you give to your site.
Server address - the domain name of your site, e.g. fred.com
User name - this is the specific user name for FTP which they gave you.
Password - this is the password they gave you for FTP, not the password for your account.
Directory/Path - leave blank to have an index.html file at root level and the site in a folder with its name, so that entering just the domain name takes you to the site. Or if you want it within a folder, enter the folder name.
Protocol: FTP
Website URL os the address which will reach your home page: if there is nothing in the Directory/Path field it will be just the domain name.

Try unmounting the volume on your iMac using Disk Utility. Then mount it again. You may need to reboot the laptop or relaunch its Finder process (using the Force Quit window) after remounting the drive on your iMac. Remember that no process may be accessing any files on the drive you plan to unmount, or the unmount will fail. Unmounting and remounting an external drive on my iMac made it become visible on my MacBook Pro after it had disappeared.
