Hope I got this straight, and this is the place to post questions:
Have made a persistent USB of Ubuntu 18.04. Which worked fine until I tried to boot my mac mini (2009) It booted fine for a couple of times then the boot partition got messed up. It won't even boot on a PC now. Here's the error message:
(initramfs) Mount: mounting/cow on/root failed: Invalid argument overlay mount failed.

I put a lot of time into creating and setting this up with apps etc. Is there a way to rectify this? 

Thanks, Charles

Just upgraded to 20.04. Had a nightmare to get firefox to play online videos.
Took me days! to find the solution. Can't believe conical would send out a distro with faulty firefox. Anyway, in case you have the same problem here what fixed it for me:  
If those streaming services use DRM, you must enable DRM in Firefox's settings: Preferences -> General -> Play DRM-controlled content You might also have to install package libavcodec-extra to get the codecs: sudo apt install libavcodec-extra

However, I've also been trying to get Brave to view videos too, same error "102630"   Has anyone figured that one out yet.

Audacity fouled up, have tried

sudo apt-get remove audacity

sudo apt-get purge audacity<br><br><br>sudo add-apt-repository ppa:ubuntuhandbook1/audacity

2. After adding the PPA, you can upgrade the editor using Software Updater (or Updater Manager).

Or just run below commands one by one in terminal:

sudo apt-get update

sudo apt-get install audacity

Detailed errors from the package manager follow:

When I launch Audacity I get an error about something fails at startup.

well, was gonna try and remove and again so I post the messages in the terminal.
And discovered that there is now another copy of audacity that seems to work ok. But the other one still won't launch?
the audacity icons are different sizes, the big one won't launch. I assume one of these is the snap pkg. ?????

Charles you are dealing with an older OS that has less than 10 months before End of Life and attempting to use an old version of Audacity by installing via ppa which should work if you trust the owner of the ppa.  I have no experience there.  Recommend that you launch your favorite web browser and attempt to find a solution on the www.  Or go to the Ubuntu Forums, https://ubuntuforums.org/ or Ask Ubuntu, https://askubuntu.com/ and ask the question.  Both are free forums and only require you to register to ask a question.  You are free to search the forums for a solution that may have already been asked and answered.

Exhibit A: Senate Bill 4051, the “Lawful Access to Encrypted Data Act”, which was quietly introduced last week when everyone’s attention was consumed elsewhere.

At its core, the LEAD Act is an encryption killer. It aims to require technology companies to build ‘back doors’ into their products to ensure that the government can remotely access your data, your device, and your life.

Under the LEAD Act, this practice would become illegal. Apple would no longer be able to offer device encryption, and they’d have to provide a way for the federal government to remotely access your device, and all of its contents. The same goes for your favorite chat applications.

Facebook will be obligated to build in a ‘back door’ for the government to remotely access your conversations.

LEAD also requires developers of operating systems, like Microsoft Windows and Apple’s MacOS, to provide backdoor access to your computer.

It’s extraordinary to think of how far-reaching the effects of this legislation will go.

For example, do you use an online password manager like OnePassword?

They will also be required to give the government access to your data… which essentially would give the government access to EVERYTHING you do online.

Do you upload files and photos to iCloud? Yup. That too. Apple will be required to build a back door and give the government access to your data.

Any ‘zero knowledge’ encryption, whether it’s for storing files, sharing photos, texting friends, making video calls, sending encrypted emails, etc., will become illegal under this legislation.

And to be crystal clear about what that means, CRYPTOCURRENCY will effectively become illegal under the LEAD Act as well.

That’s right. Cryptocurrency relies on data encryption too.

Your ‘wallet’ is essentially a public key / private key combination. And in theory, only you are supposed to have access.

But that’s exactly what this legislation aims to prevent. The government wants backdoor access to everything.
