Hi, I'm trying to help to an elderly person which uses Debian stretch to access the gov.il interface, she has the biometric id card and I have a generic smart card reader (GemPC Key SmartCard Reader) that I wished to give her so she could auth to the system. I don't have a biometric id , so I can't verify if we can even use the browser to access the web interface. Does anyone have a biometric id , and can check if they can login using FF / chromium or stuff like that ?

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? (y/N) y Executing `/snap/bin/canonical-livepatch disable` An unexpected error occurred: Failed running command '/snap/bin/canonical-livepatch disable' [exit(1)].

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