war story: gtalug.org's filled up
by D. Hugh Redelmeier 06 Apr '23

06 Apr '23

(This post is also a test of whether the mailing list is working.) GTALUG's server's filesystem filled up: little disk space left. I discovered this when I tried to do "apt update; apt full-upgrade". The second step failed, saying that /var/cache/apt/archives had no room. This means that / has no room because / contains that directory. Tip: "df /some/path" will tell you how much space is used on the filesystem containing /some/path and it will tell you the mount point of that file system. I wandered around the filesystem, doing: sudo df -s * | sort -n This command lists things in the current directory, and their sizes, largest last. (It skips things with names starting with ".".) Pretty soon, I found that most of the space was taken up by /var/cache/apt/archives after all. This kind of surprised me. Googling got me to others with this problem. The advice: sudo apt autoclean That gave back (only) 3% of the disk. That directory was still way too big. Most of the space was taken by 35 versions of gitlab-runner. I have no idea why we need multiple versions. Violence is sometimes the answer. sudo apt clean That left only 32% of / used. Note /var/cache/apt/archives is only a cache. If the system wants any of these, it should be able to find them in a repo.

I imagine not. I don't see gitlab-runner as a package in my Ubuntu repos, but I believe the 153 versions are all different versions that currently exist in the repo. I tested this with Firefox, and `apt show firefox` contained: > Version: 111.0.1+build2-0ubuntu0.22.04.1~mt1 > > ... > > "N: There are 2 additional records. Please use the -a switch to see > them." Whereas `apt show firefox -a` indicates there are versions 110.x, 111.x and snap available. So, all the un-removed packages in cache corresponding with existing entries in the repo may explain why `apt autoclean` didn't clear up much space (if I recall the situation correctly), since `man apt autoclean` says: > autoclean (and the auto-clean alias since 1.1) Like clean, autoclean > clears out the local repository of retrieved package files. The > difference is that it only removes package files that can no longer > be downloaded "Can no longer be downloaded"... Still, weird that the repo contains so many out-of-date versions; I'd have expected them to be removed when they're deprecated. Also, I *think* that's where `apt mark minimize-manual` can clear out some of the cruft that exists post-upgrade. Might be worth a try? rb [Re-directed this to the mailing list, since hopefully there's something of interest to the general community in here and nothing confidential.]

Update borked my system
by Evan Leibovitch 30 Mar '23

30 Mar '23

Hi all. Wondering if anyone can help with this. A power glitch happened while I was updating a KDE Neon system and on reboot all sorts of things are wonky. KDE starts up fine on bootup but there are no window toolbars. All apps load at the upper right of the screen and can't be moved because there is nothing to drag and no keyboard shortcuts will work. An attempt to complete the upgrade using `pkcon update` (the KDE Neon version of `apt dist-upgrade`) spits out a slew of errors (attached). The database is not corrupt (`pkcon repair` reports no problems) but there seem to be major pieces either refusing to install or "held back". Is there a command that can let me just force everything to the current stable release without me having to go through the whole install-from-usb-stick thing? There's nothing critical on that installation so a fresh instrall is more of a PITA than critical problem. Still, it took me a lot of time to set up my apps Thanks for any help. I like KDE Neon, it's a like "Kubuntu without snaps but with the newest KDE". Evan Leibovitch, Toronto Canada @evanleibovitch / @el56

Modems – does it matter?
by Yoshua Wakeham 27 Mar '23

27 Mar '23

Hi all! My toddler spilled a cup of water on our TekSavvy modem (Technicolor TC4350), and now we need a new modem. Welp. TekSavvy sent us the list of compatible modems. My question is – are there any important considerations for this decision other than price and (immediate!) availability? I don't think I've ever actually had to choose my modem, so I don't know what I don't know. Here are the options, all opinions welcome: - Technicolor CGA4234DGW WiFi - Firmware must be CGA4234-P15-13-CA902-c0200r181-191007 - Hitron CODA-4680 WiFi - Firmware must be 7.1.1.2.2b9 - Teksavvy sells for $199.95 or $16.66/month for 12 months + $10 shipping. We also rent for the cost of $8 per month. - Hitron CODA-45 - Firmware must be 7.2.4.3.1b3 - Teksavvy sells for $139.95 or $11.66/month for 12 months + $10 shipping. We also rent for the cost of $6 per month. (Not recommended to be acquired outside Teksavvy due to firmware) - Technicolor TC4400 - Firmware must be SR701343-190628-D - (Usually available at Canada Computers) - Compal Broadband Networks Inc. (CBN) CD8000 - Firmware must be 7.13.198.12 - (Usually available at Canada Computers) - Sercomm DM1000 - Firmware must be V1.12.03.011 - Compal Broadband Networks Inc. (CBN) CH8568 WiFi- Firmware must be CH8568-7.13.198.53-NOSH Thanks! Yosh -- *Yoshua Wakeham* yoshwakeham(a)gmail.com

Not all kernel fixes backported to CentOS
by Giles Orr 26 Mar '23

26 Mar '23

I think we have a few CentOS users on this list, so this may be a bit alarming: https://www.neowin.net/news/google-discloses-centos-linux-kernel-vulnerabil… Here are a couple of the important chunks: "As detailed in the technical document here, Google Project Zero's security researcher Jann Horn learned that kernel fixes made to stable trees are not backported to many enterprise versions of Linux. To validate this hypothesis, Horn compared the CentOS Stream 9 kernel to the stable linux-5.15.y stable tree. For those unaware, CentOS is a Linux distro closest to Red Hat Enterprise Linux (RHEL) and its version 9 is based on the linux-5.14 release." "As expected, it turned out that several kernel fixes have not been made deployed in older, but supported versions of CentOS Stream/RHEL. Horn further noted that for this case, Project Zero is giving a 90-day deadline to release a fix, but in the future, it may allot even stricter deadlines for missing backports ..." -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com

Re: [GTALUG] analog land line phone service in Toronto?
by Steve Petrie 25 Mar '23

25 Mar '23

Karen, I use Bell Fibe service for which Bell provided a Sagemcom HomeHub 4000 modem, a large white plastic tower device. (I got the Bell technician wall mount my Home Hub 4000 modem). On thes back of the Home Hub 4000 are two (2) green-coloured jacks marked as TEL 1 and TEL 2 (with embossed legend not easy to read). I have an ancient Northern Telecom "Jazz" analog (land line compatible) phone plugged in to the TEL 1 jack on the Home Hub 4000 modem. This ancient analog phone works fine but sometimes it takes a few seconds for the dial tone audio hum to start, when I pick up the phone's handset. You mentioned that "Bell no longer offering analog, only fiberactic which seems to interact with the specialty phone I use due to disability." Two (2) questions occur to me: Q#1: Do you have your specialty phone plugged into the TEL1 jack on a Bell Fibe Home Hub 4000 modem ?? Q#2: Does Bell Canada tech support explain why your specialty phone is not working properly through your Bell Fibe service ?? Steve Petrie apetrie(a)aspetrie.net

distro: Amazon Linux 2023

Does anyone use this? It seems to be based on Fedora but with a longer support cycle. [interesting] Does it only work on AWS? Mostly. [too bad] https://docs.aws.amazon.com/linux/al2023/ug/what-is-amazon-linux.html https://twitter.com/stewartsmith/status/1636378983909687309 https://docs.aws.amazon.com/linux/al2023/ug/release-cadence.html >From https://aws.amazon.com/linux/amazon-linux-2023/faqs/ Q: Can I use AL2023 outside of AWS? A: AL2023 images can be used outside of AWS, however, these images are not covered by AWS Support Plans when used outside of AWS. When Amazon Linux 2023 becomes Generally Available, it will be provided as a virtual machine image for on-premises use, enabling you to easily develop, test, and certify applications from a local development environment. This option is not available during the preview.

New WiFi router?
by William Park 09 Mar '23

09 Mar '23

Hi all, I was upgraded (by my ISP) from Cable 75 (75M/10M) to Cable 100 (100M/30M). It turns out my router (Asus RT-N66U) maxes out at 85M/30M. Connecting directly to the modem, I get full 100M/30M. So, it's time for a new router. It's been long time since I shopped for a router. Which one do you recommend?
