Ubiquity UniFi SDN – Server status “UniFi Controller is starting up… Please wait a moment”

Posted by jpluimers on 2019/02/22

When your UniFi Cloud Key web interface shows this [Archive.is] after upgrading:

 

UniFi Controller is starting up…

Please wait a moment

 

Then you just ran into a bug which seems to occur most with 5.9.29 of the UniFi software: [Archive.is] “UniFi Controller is starting up…” “Please wait a moment” “5.9.29” – Google Search

The easiest way is to restore from a backup: this usually works.

For that you need ssh access, which usually is with the ubnt user. But you could have made life more complicated when you followed these:

Steps from [WayBack] UniFi Controller is starting up… Please Wait A Moment – Ubiquiti Networks Community (thanks [Archive.is] About mrfoxdk – Ubiquiti Networks Community!):

  1. SSH to the Unifi CloudKey
  2. dpkg -P unifi
  3. Open a browser and browse the URL of CloudKey
  4. Login
  5. Press “Install” under UniFi
  6. Wait for the process to complete, and then wait a bit for the service to be brought online.
  7. Recover the configuration backup from the latest backup

Removing and reinstalling the UniFi software, then restore from backup

Step 2 above will purge the unifi software of the cloud key as per dpkg --help:

Many Mac OS X / MacOX / whatever versions: Unable to modify the volume with the keyboard – Ask Different

Posted by jpluimers on 2019/02/22

This has happened to me on most Macs with most Apple Mac OS X / MacOS / whatever versions: the built in sound controls for internal speakers and head phones fail to work (keyboard shortcuts and UI both fail).

The solution at [WayBack] mavericks – Unable to modify the volume with the keyboard – Ask Different works, but be sure to require the kernel module steps:

open up a Terminal window and run:

sudo killall coreaudiod
sudo kextunload /System/Library/Extensions/AppleHDA.kext 
sudo kextload /System/Library/Extensions/AppleHDA.kext

When Windows 10 doesn’t recognise your DVD device any more

Posted by jpluimers on 2019/02/22

Yes, some people still use DVD devices. My mentally retarded brother does every now and then, so it was a big problem that one day he could not put play a photo DVD any more.

This happened:

The selected device was gone. Reboots (including cold ones) didn’t help.

What helped was selecting the “Dual Channel PCI IDE Controller”, remove it, then reboot so Windows would try to re-install the drivers. After that the DVD drive appeared again.

Later I found these two links with similar solutions:
