Ubuntu issues

Hi, I have two Ubuntu 18.04.6 LTS servers (droplets) which I can't and don't want to upgrade right now. One of them is running pip==22.2.2 and when I run this command I get this output: pip freeze|grep -i certb certbot==2.10.0 certbot-apache==2.10.0 certbot-dns-digitalocean==2.10.0 The other one is running pip==21.3.1 and when I run this command I get this output: pip freeze|grep -i certb /usr/lib/python3/dist-packages/secretstorage/dhcrypto.py:15: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography and will be removed in a future release. from cryptography.utils import int_from_bytes certbot==1.23.0 certbot-apache==1.23.0 certbot-dns-digitalocean==1.23.0 certbot-dns-route53==1.23.0 I want to know how do I upgrade pip, certbot and optionally Python to its latest version in both machines, and especially the second machine? I also have two machines with Ubuntu 22.04.4 LTS. There I have problems with Ubuntu pro: # sudo pro detach Detach will disable the following service: livepatch Are you sure?

off topic (but I don't know who to ask) - probably?? ISP problem
by Shlomo Solomon 02 Jun '24

02 Jun '24

I teach computer networking and the latest assignment I gave my students was to use Python and Scapy to emmulate traceroute. The code is simple: - send an ICMP packet with TTL = 1 which will fail but return the first hop address - continue sending ICMP packets - each time increasing the TTL to get the next hop - if the ICMP reply is NOT an error, we have arrived. None of my student submissions worked, which was strange, so I tried my own code which I know is correct. It also did not work. The error messages arrive for each hop, but it seems that the NO ERROR message (when the destination is reached) is not arriving. I also checked with Wireshark and see error replies (as I should) for each hop, but then (when I assume I have reached the destination) there is no reply. I then tried disconnecting my computer from my ISP and connected via a Hotspot on my phone - PROBLEM SOLVED. So this seems to be a problem with my ISP (019) blocking some traffic. But I don't know what the next step is. If I call customer service, I'm sure no-one will understand what I want. BTW - ping and the "real" traceroute work fine. I also looked at router settings, but did not find anything suspicious. Can anyone suggest how to explain my problem to my ISP? ALSO - if there is anyone using 019, I would be happy to send my code for testing to verify that this is really a problem with 019. -- Shlomo Solomon http://the-solomons.net Claws Mail 4.0.0 - KDE Plasma 5.24.7 - Kubuntu 22.04

Do up-to-date Nvidia drivers suppress output to DVI interface?
by Omer Zak 31 May '24

31 May '24

My Linux desktop has two displays (DELL and Samsung), Nvidia GP107 (GeForce GTX 1050 Ti) with HDMI and DVI outputs. The operating system is Linux Debian Bullseye (version 11.9). Today I upgraded the Nvidia proprietary drivers from version 550.54.15-1 to version 555.42.02-1 (several .deb packages) and as a result, only the HDMI-connected display works now in X-Window. When the computer boots, the text display is via the DVI screen, and when X-Window works, the DVI screen displays nothing and information is displayed on the HDMI-connected screen. The output of 'xrandr | grep connect' is as follows: DVI-D-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 476mm x 267mm HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm I saw no obvious error messages in /var/log/Xorg.0.log nvidia-smi does not display anything abnormal. glxgears works on the screen connected via HDMI. I tried few versions of /etc/X11/xorg.conf (/etc/X11/xorg.conf.d/ is empty) including having no xorg.conf at all. All of them yield the same results (only the HDMI-connected screen displays stuff). Questions: 1. Does anyone know if Nvidia disabled, in version 555.42.*, their DVI support or changed its configuration options? 2. What, if any, configuration options should I check?

Hi all, The Wednesday, 5/1/2024 GoLUG meeting commences at 7pm Eastern Daylight Time online at meet.jit.si/golug . I'll be late because of my kids' birthday (this happens every May), but when I get there I'll show a simple no Javascript, CSS-only web-menu and a 100% CSS, no graphics knockoff of the logo from TV show Law & Order. This gives plenty of time for others to show off various interesting tricks they've created. Hope to see you there.

df problem (and work around) - kernel 5.15.0.102-generic
by Shlomo Solomon 16 Apr '24

16 Apr '24

I had a problem with df on a cif mount. I Googled and found a work around. Thought this might interest others so including 2 links. TL;DR - There is a bug in 5.15.0.102-generic. Reverting to 5.15.0.101-generic solved the problem. I hope/assume this will be fixed in the next update. https://forums.linuxmint.com/viewtopic.php?t=417371 https://askubuntu.com/questions/1509987/cifs-on-22-04-lts-has-something-cha… -- Shlomo Solomon http://the-solomons.net Claws Mail 3.17.5 - KDE Plasma 5.18.5 - Kubuntu 20.04

Hebrew anti-clockwise clock
by Boruch Baum 13 Apr '24

13 Apr '24

I stumbled upon an ancient (year 1995) X11 app called xarclock that runs anti-clockwise. You might figure that its purpose was to mimic the Medieval Hebrew clock in Prague, but the author seems to have just wanted to gag life in the Southern hemisphere, where sundials (he claims) run in reverse. I added Hebrew support and published it to github along with a debian package and a stand-alone executable. Debian already has the original version (patched) in its repositories. Is there a debian person (preferably a developer) on the list who can guide me how to suggest my modifications be added to the debian package? https://github.com/Boruch-Baum/xarclock-hebrew https://github.com/Boruch-Baum/xarclock-hebrew/releases/tag/v1.0 A modern QT version of this would be fun, but I don't know QT programming. -- hkp://keys.gnupg.net CA45 09B5 5351 7C11 A9D1 7286 0036 9E45 1595 8BC0

Linux Campfire Tales at GoLUG, 4/3/2024
by Steve Litt 03 Apr '24

03 Apr '24

Hi all, GoLUG meeting where anyone who wants to can share their Linux or BSD story. ====================================================================== What: Online: Linux Campfire Tales Who: Anyone wanting to tell a Linux story When: Wednesday 4/3/2024 at 7PM Eastern Daylight Time Where: Jitsi online presentation, https://meet.jit.si/golug [1] ====================================================================== Everybody has a Linux or BSD story they'd like to tell. Now's your chance. It can be from 1992 or from yesterday, or anywhere in between, your choice. Has Linux ever saved your bacon? Slapped you in the face? How did you transition into Linux? These stories can be first person or third person or just something you heard about. I imagine more than one of us will relay our experience with the recent xz Utils backdoor: I know that mess made my heart skip a few beats before realizing my distro wasn't affected. Hope to see you all there.

Debian 12 (bookworm) vs. Nvidia?
by Omer Zak 25 Mar '24

25 Mar '24

I have upgraded a laptop from Debian 11 (Bullseye) to Debian 12 (Bookworm) Now I am running into trouble when trying to build DKMS modules needed by nvidia-driver (the proprietary one) on the most recent kernel version (I tried both 6.1.76-1 and 6.6.13-1~bpo12+1). There are some compile-time errors (different errors in different attempts). Is there any information about known problems of getting Nvidia software to interoperate with Debian 12 (Bookworm) working on up-to- date kernels? --- Omer Zak -- My Commodore 64 is suffering from slowness and insufficiency of memory; and its display device is grievously short of pixels.
