Q: RoamingProfiles under GN/Linux? What's your Best Practice?

This post is an open question to the wide range of GNU/Linux site admins out there. Possibly some of you have the joy of maintaining GNU/Linux also on user endpoint devices (i.e. user workstations, user notebooks, etc.), not only on corporate servers.

TL;DR; In the context of a customer project, I am researching ways of mimicking (or inventing anew) a feature well known (and sometimes also well hated) from the MS Windows world: Roaming User Profiles. If anyone does have any input on that, please contact me (OFTC/Freenode IRC, Telegram, email). I am curious what your solution may be.

The Use Case Scenario

In my use case, all user machines shall be mobile (notebooks, convertibles, etc). The machines maybe on-site most of the time, but they need offline capabilities so that the users can transparently move off-site and continue their work. At the same time, a copy of the home directory (or the home directory itself) shall be stored on some backend fileservers (for central backups as well as for providing the possibility to the user to login to another machine and be up-and-running +/- out-of-the-box).

The Vision

Initial Login

Ideally, I'd like to have a low level file system feature for this that handles it all.

My Work on Debian LTS (March 2020)

In March 2020, I have worked on the Debian LTS project for 10.25 hours (of 10.25 hours planned).

LTS Work

  • Frontdesk: CVE Bug Triaging for Debian jessie LTS: libpam-krb5, symfony, edk2 (EOL), icu, twisted, yubikey-val, netkit-telnet(-ssl), libperlspeak-perl (new EOL). and glibc.
  • Upload to jessie-security: tinyproxy (DLA-2163-1 [1], 1 CVE, 1 severe bug [2]).
  • Revisit CVE-2015-9541 in jessie's qtbase-opensource-src and agree with Dmitry Shachnev from Debian's KDE/Qt Team about tagging this CVE '<ignored>' in Debian's security tracker. The proposed upstream patch uses an API not available in jessie's Qt5 version (QStringView API) and the serious of patched ot be applied would be quite invasive.
  • Prepare upload of libpam-krb5 4.6-3+deb8u1 (1 CVE) (will be uploaded during the day).
  • Look closer into CVE-2019-17177 for FreeRDP v1.1 (and decide to ignore it, as patchwork would have to be applied all over the code).

UBports: Packaging of Lomiri Operating Environment for Debian (part 02)

Before and during FOSDEM 2020, I agreed with the people (developers, supporters, managers) of the UBports Foundation to package the Unity8 Operating Environment for Debian. Since 27th Feb 2020, Unity8 has now become Lomiri.

Recent Uploads to Debian related to Lomiri

Over the past 7-8 weeks the packaging progress has been slowed down due to other projects I am working on in parallel.

Mailman3 - Call for Translations (@Weblate)

TL;DR; please help localizing Mailman3 [1]. You can find it on hosted Weblate [2].The next component releases are planned in 1-2 weeks from now. Thanks for your contribution! If you can't make it now, please consider working on Mailman3 translations at some later point of time. Thanks!

Time has come for Mailman3

Over the last months I have found an interest in Mailman3. Given the EOL of Python2 in January 2020 and also being a heavy Mailman2 provider for various of my projects and also for customers, I felt it was time to look at Mailman2's successor: Mailman3 [1].

One great novelty in Mailman3 is the strict split up between backend (Mailman Core), and the frontend components (django-mailman3, Postorius, Hyperkitty). All three are Django applications. Postorius is the list management web frontend whereas Hyperkitty is an archive viewer. Other than in Mailman2, you can also drop list posts into Hyperkitty directly (instead of sending a mail to the list). This makes Hyperkitty also some sort of forum software with a mailing list core in the back. The django-mailman3 module knits the previous two together (and handles account management, login dialog, profile settings, etc.).

Looking into Mailman3 Upstream Code

Some time back in midst 2019 I decided to deploy Mailman3 at a customer's site and also for my own business (which still is the test installation). Living and working in Germany, my customers' demand often is a fully localized WebUI. And at that time, Mailman3 could not provide this.

Today's address to the public by the German chancellor. I am totally chiming in with here. Please all across the world, help to #FlattenTheCurve:

Time for home office! Time for X2Go?

Most of us IT people should be in home office by now. If not, make sure you'll arrange that with your employers, cooperation partners, contractors, etc. Please help flatten the curve.

X2Go as your Home Office solution

If your computer at work runs a GNU/Linux desktop and you can SSH into it, then it might be time for you to try out X2Go [1]. Remote desktop access under GNU/Linux.

Free Support for simple Client-Server Setups

If your daily work is related to health care, municipal work, medical research, etc. (all those fields that are currently working under very high demands), please join the #x2go IRC channel on Freenode [2] and I'll do my very best to help you with setting up X2Go.

Professional Support for Large Scale Setups

If you run a business and need X2Go support site-wide, brokerage support, etc. please consider asking for professional support [3].

My Work on Debian LTS (February 2020)

In February 2020, I have worked on the Debian LTS project only for 5.75 hours (of 20 hours planned). I gave back 12 hours to the pool and reduced my availability to 8 hours per month.

Unfortunately, last month I got too distracted by other interesting and challenging projects, and also by some intense personal topics.

I herewith send my apology to all LTS team members and all Debian LTS users for not having completed my planned LTS workload.

LTS Work

  • Take a deeper look at cacti and mark cacti Debian jessie LTS as not affected by CVE-2020-8813
  • Study open vulnerability reports in ansible (no fixes available, yet, as of end of February 2020)
  • Work on fixing CVE-2015-9541 in qtbase-opensource-src (still work in progress)

Lomiri - Operating Environment for Everywhere

It is my pleasure to spread the word about the new name of Unity8 (UI running on the Ubuntu Phone and the Ubuntu Tablet) and its related projects: Lomiri (low-mee-ree).

Lomiri: New Name, Same Great Unity8

Lomiri is the operating environment for everywhere: phone, tablet, laptop, and desktop. It features a slick and easy-to-use interface based on the design of its predecessor, Canonical's Unity desktop environment.

Change is never Easy

I was honoured to witness the process of the long outstanding name change +/- in real time over the last couple of days / weeks. I was touched by the gentleness of the discussion and the weighing of pros and cons, this name and that name; also by the jokes being injected into the discussions.

Dalton Durst, release manager on the UBports [2] team, explains in depth [1] about the reasoning and necessities behind the name change. Please (esp. if you feel sad or irritated by the name change), read the official announcement and detailled explanation. If you need time to adjust, Dalton's explanations will help.

Have fun watching. (Access might not be possible world-wide).

MATE 1.24 landed in Debian unstable

Last week, Martin Wimpress (from Ubuntu MATE) and I did a 2.5-day packaging sprint and after that I bundle-uploaded all MATE 1.24 related components to Debian unstable. Thus, MATE 1.24 landed in Debian unstable only four days after the upstream release. I think this was the fastest version bump of MATE in Debian ever.

Packages should have been built by now for most of the 22 architectures supported by Debian. The current/latest build status can be viewed on the DDPO page of the Debian+Ubuntu MATE Packaging Team [1].

Please also refer to the MATE 1.24 upstream release notes for details on what's new and what's changed [2].

Credits

One big thanks goes to Martin Wimpress. Martin and I worked on all the related packages hand in hand. Only this team work made this very fast upload possible. Martin especially found the fix for a flaw in Python Caja that caused all Python3 based Caja extensions to fail in Caja 1.24 / Python Caja 1.24. Well done!

Another big thanks goes to the MATE upstream team. You again did an awesome job, folks. Much, much appreciated.

Last but not least, a big thanks goes to Svante Signell for providing Debian architecture specific patches for Debian's non-Linux distributions (GNU/Hurd, GNU/kFreeBSD). We will wait now until all MATE 1.24 packages have initially migrated to Debian testing and then follow-up upload his fixes. As in the past, MATE shall be available on as many Debian architectures as possible (ideally: all of them).
