[15:01] <malcom2073> Unsure if this is the right place to ask, but I'm having an issue connecting to any PPA. Whenever I add a PPA and apt-get update in Ubuntu, I get a "Could not connect to ppa.launchpad.net:80 
[15:02] <malcom2073> I can ping the PPA, and I can wget from it, and "mtr" shows it is alive and up
[15:03] <oerheks> what ppa exactly?
[15:04] <oerheks> and for what ubuntu version?
[15:07] <malcom2073> Ubuntu 20.04, I've tried three or four PPA's now, none work. The one currently in question is: https://launchpad.net/~mc3man/+archive/ubuntu/focal6
[15:08] <malcom2073> It's definitely something wrong with my configuration/network, unsure how to diagnose further
[15:09] <malcom2073> I can't wget the debians themselves, I can only wget the main ppa.launchpad.net page
[15:14] <malcom2073> This is only an issue on one computer. On a ubuntu 16.04 machine, I can wget the exact same debian (https://launchpad.net/~mc3man/+archive/ubuntu/focal6/+files/audacious-dev_4.0-1~focal_amd64.deb for instance) without issue
[15:17] <oerheks> have you tried to reboot the router? often weird connection issues get solved by this, you do can run apt update apt upgrade?
[15:22] <malcom2073> I have tried resetting the router and wifi AP, as well as rebooting the machine. I ran apt-get upgrade as well, and rebooted afterwards, but have the same failures: apt-get update fails with could not connect/connection refused, "wget ppa.launchpad.net" succeeds, wget of debian file fails with connection refused.
[15:24] <malcom2073> Uh... I tried the wget a second time, it succeeded, but then failed a third time.... you know what, I've got a sneaking suspicion about my wifi card... let me try something
[15:28] <malcom2073> Huh nope, hard-wired ethernet into the router and same behavior
[15:32] <malcom2073> This is a fresh install of 20.04 as of this morning. The wifi drivers didn't work out of the box so I had to install the broadcom b43 driver manually. I need to swap this over to a SSD, so I may do that, reinstall fresh, and just try it with ethernet, who knows what else the drive process messed up
[15:33] <malcom2073> It's really bizzare that the only thing failing is my connection to launchpad, and only on this particular computer. I can browse other websites, ssh into services, I even tried to VPN to my cloud and it worked fine
[15:43] <realtime-neil> malcom2073: here's an anecdatum:

[15:45] <realtime-neil> malcom2073: is your ISP decently well-behaved?
[15:47] <malcom2073> Heh, absolutely not my ISP is terribly behaved: Verizon wireless. That being said, I've now tested on two different computers, one on WiFi, and one on Ethernet to the same router. Neither had the issue, and both were able to apt-get update and wget successfully, so it's gotta be something on this computer. I'm in the process of reinstalling fresh, just to make sure the driver install I did, didn't mess up something in the networking stack in weird ways
[16:17] <malcom2073> So I reinstalled, but had the same issue. Did an apt-get upgrade, same issue. Found a random site on google that suggested that invalid certificates can cause this, so I reinstalled ca-certificates and now when I run apt-get update, it works about 20% of the time, and says connection refused for the other 80%. Also, us.archive.ubuntu.com has started having the same issue
[16:17] <malcom2073> Either way, totally not a launchpad issue, so I'll go away and figure this out :)
[16:17] <malcom2073> Thanks!
[16:42] <oerheks> this makes no sense to me ..
[17:05] <malcom2073> Nor to me, but it seems if I put apt-get in a loop, and only exit on success, I am able to eventually successfully download everything after the third or fourth try. The hardware is quite literally 12 years old, so I'm going to make do with this to get things done until new hardware comes in next week and then throw it in the trash
