  • Ubuntu Weekly Newsletter 605

    Welcome to the Ubuntu Weekly Newsletter, Issue 605 for the week of November 10 – 16, 2019. The full version of this issue is available here.

  • Russell Coker: 4K Monitors

    I like having lots of terminal windows on my desktop. For common tasks I might need a few terminals open at a time and if I get interrupted in a task I like to leave the terminal windows for it open so I can easily go back to it. Having more 80*25 terminal windows on screen increases my productivity. My previous monitor was 2560*1440 which for years had allowed me to have a 4*4 array of non-overlapping terminal windows as well as another 8 or 9 overlapping ones if I needed more. 16 terminals allows me to ssh to lots of systems and edit lots of files in vi. Earlier this year I had found it difficult to read the font size that previously worked well for me so I had to use a larger font that meant that only 3*3 terminals would fit on my screen. Going from 16 non-overlapping windows and an optional 8 overlapping to 9 non-overlapping and an optional 6 overlapping is a significant difference. I could get a second monitor, and I won’t rule out doing so at some future time. But it’s not ideal.

Announcing extrepo

Filed under
Debian

While there is a tool to enable package signatures in Debian packages, the dpkg tool does not enforce the existence of such signatures, and therefore it is possible for an attacker to replace the (signed) .deb file with an unsigned variant, bypassing the whole signature.

In an effort to remedy this whole situation, I looked at creating extrepo, a package that would download repository metadata from a special-purpose repository, verify the signatures placed on that metadata, and if everything matches, enable the repository by creating the necessary apt configuration files.

This should allow users to enable external repository "foo" by running extrepo enable foo, rather than downloading a script from foo's website and executing it as root -- or other similarly insecure options.

Debian Moves Closer To Voting On Proposals Over Init System Diversity

Filed under
Debian

Following the decision by Debian Project Leader Sam Hartman to seek a general resolution over init system diversity and just how much Debian developers care about supporting systemd alternatives, the general resolution vote is moving closer.

The text is now laid out over three proposals drafted by Sam Hartman in weighing the importance of systemd / init system diversity by Debian developers.

The three choices include affirming init diversity, focusing on systemd but supporting the exploration of alternatives, and focusing on systemd for the init system and other facilities.

Updated Debian 10: 10.2 released

Filed under
Debian

The Debian project is pleased to announce the second update of its stable distribution Debian 10 (codename buster). This point release mainly adds corrections for security issues, along with a few adjustments for serious problems. Security advisories have already been published separately and are referenced where available.

Please note that the point release does not constitute a new version of Debian 10 but only updates some of the packages included. There is no need to throw away old buster media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror.

Those who frequently install updates from security.debian.org won't have to update many packages, and most such updates are included in the point release.

New installation images will be available soon at the regular locations.

Debian Project Releases Linux Security Updates to Patch Latest Intel CPU Flaws

Security
Debian

As reported earlier this week, four new security vulnerabilities have been discovered in the Linux kernel and with an impact on Intel CPUs, namely CVE-2019-11135, CVE-2018-12207, CVE-2019-0154 and CVE-2019-0155, which may lead to privilege escalation, information leak, as well as denial of service.

Following on the footsteps of Canonical and Red Hat, Debian Project has also released new Linux kernel security patches, along with new intel-microcode updates to mitigate all these new vulnerabilities in the Debian GNU/Linux 9 "Stretch" and Debian GNU/Linux 10 "Buster" operating systems.

Debian reconsiders init-system diversity

Filed under
Debian

The immediate motivation for a reconsideration would appear to be the proposed addition of elogind, a standalone fork of the systemd-logind daemon, to Debian. Elogind would provide support for systemd's D-Bus-based login mechanism — needed to support small projects like the GNOME desktop — without the need for systemd itself. The addition of elogind has been controversial; it is a difficult package to integrate for a number of reasons. Much of the discussion has evidently been carried out away from the mailing lists, but some context on the problem can be found in this bug report. In short: merging elogind appears to be complex enough that it would be hard to justify in the absence of a strong commitment to the support of non-systemd init systems. It seems possible that this commitment no longer exists across the distribution as a whole; the purpose of a general resolution would be to determine whether that is the case or not.

  • Python dataclasses and typing

    I'm going to preach the wonders of Python dataclasses, but for reasons of interested to those who have already gone down the delightful rabbit-hole of typed Python. So let me start with a quick plug for mypy if you haven't heard about it.

    (Warning: this is going to be a bit long.)

Shirish Agarwal: A tale of unfortunate coincidences and incidents

I went back to the vendor with my old stock SMPS and it worked but found that grub2 menu was missing. It was just plain booting to windows 10. I started a thread at debian-user trying to figure out if there was some issue at my end, maybe some grub variable had got lost or something but the responses seemed to suggest that something else had happened. I also read through some of the UEFI documentation on wikipedia and web, I didn’t go to much depth as that would have been distracting as the specification itself is evolving and is subject to change. I did find some interesting bits and pieces but that is for a later date perhaps. One of the things I remembered from my previous run-ins with grub2 issues is that supergrub2 had been immensely useful. Sadly though, the version which I tried as stable was dumping me to grub rescue instead of the grub menu when I used the ISO image on a thumb drive. I could have tried to make a go for it but was too lazy. On an off-chance I looked at supergrub2 support and did find that somebody else also have had the same exact issue and it was reported. I chimed in and tried one of the beta versions and it worked which made me breathe easier. After getting into debian, I tried the old $ sudo update-grub which usually fixed the issues. I again tried to boot without using the help of the usb disk but failed as it again booted me into MS-Windows environment.
