Re: [ubuntu-studio-devel] US still alive !

[Erich Eickmeyer]

I have a lot of ideas to help revitalize Ubuntu Studio, but I’m, unfortunately, 
not the one with the keys to the social media sites. Alan Pope of Canonical is 
now aware that I’m on the project, and maybe we’ll see where things go from 
there. As for the social media accounts, I don’t even know who would have the 
keys to those in order to get some publicity out there, but maybe Set might 
know. Either way, it’s good to see some attention being drawn.

I've modified apport back to include warnings but at the same time to
address the privacy issue have also changed apport to only include
JournalErrors when the report is a crash report as those reports are
private by default. So before making a crash report public be sure to
review the JournalErrors attachment for private information. And of
course you can always ask the bug reporter to run the same command,
'journalctl -b --priority=warning --lines=1000', and add that to their
regular bug reports if necessary.

Re: [ubuntu-studio-devel] US still alive !

[lukefromdc]

What is probably going on is that linux users are installing the base
system, then using online search tools to find what programs they
need for their workflow and installing those programs..

Re: freeipa-client missing in 18.04

[Bryan Quigley]

It looks like it's just help up now because it's failing an
autopkgtest -

This is a bug about it with more details:

If you find more about why the test is failing feel free to update
that bug with details to help get it back in.

freeipa-client missing in 18.04

[Bryce Larson]

It seems that freeipa-client was removed from the 18.04 repos.  Is it going to 
be in the final release or is another way of installing freeipa recommended for 
ubuntu 18.04?

Re: Supporting LZ4 as initramfs compressor

[Marcos Alano]

Last night I was trying to decrypt my laptop remotely. Work well
(after some research) and so on, but the point is I put Dropbear SSH
server inside initramfs and a faster decompress would be very
welcomed.

Re: [ubuntu-studio-devel] slow response ?

That is something I hope to rectify. Since I have deep contacts with some of 
the most listened-to linux podcasts, I hope to get the word out that we’re 
still a thing.

That's not the use case I brought up.

I said users of the devel series, aka ubuntu+1.

The compression vs download trade off, is irrelevant on the ubuntu+1
series, since the churn is so high anyway, that the only way to win,
is to not update every transition / archive push, and only
dist-upgrade weekly. And optimizing for users of ubuntu+1 is very
niche, in comparison to the stable series users.

I make no distinction among the stable series users - be that
"developers" or "not", they are all simply stable series users.

Bionic Beaver User Interface Freeze and nearing Final Beta reminder

[Lukasz Zemczak]

This is a gentle reminder that Bionic Beaver (18.04) is in User
Interface Freeze since last week (March 22th). Remember about that
when uploading packages into the archive as any freeze-breaking
changes per https://wiki.ubuntu.com/UserInterfaceFreeze need to have
an ubuntu-release approved exception [1].

Also, since Final Beta is planned for next week already, remember
about the nearing Beta Freeze on Monday. If you still have any high
impact changes pending for 18.04, now is the time to upload.

Thanks!

[ubuntu-studio-devel] slow response ?

[pc...@laposte.net]

Hi 
Ubuntu studio is imo the best distro for audio ( I used linux for audio
for the 1st time with agnula demudi then i switched to mac os and i'm
coming back to linux)

I use US everyday, for everything (from audio to video, firefox, and
dragon naturally speaking  pro via VM and even steam spotify molotovTV
and netflix !) But I see no advertising no infos not even a youtube
channel talking about US. that's the point. noone knows US. 

Best regards from france.
