| xmz | [15:50] <xmz> Excuse me, I would like to ask for help. | 09:13 |
| xmz | [15:50] <Guest43> yes | 09:13 |
| xmz | [15:50] <xmz> The ubuntu-22.04-preinstalled-server-riscv64+unmatched.img started with qemu, the kernel version is Linux 5.15.0-1018-generic. I compiled and installed a new kernel, but the new kernel cannot be started. It seems that u-boot needs to be set up. | 09:13 |
| xmz | [15:50] <xmz> I posted the qemu boot script and boot info here: https://dpaste.com/EKCHULY93 | 09:13 |
| === arraybolt3_ is now known as arraybolt3 | ||
| tomreyn | xmz: you seem to be using an outdated image. https://ubuntu.com/download/risc-v provides 22.04.*1* (ubuntu-22.04.1-preinstalled-server-riscv64+unmatched.img.xz) | 11:39 |
| tomreyn | this said, i do not know whether or not this will help with the issue you're running into. | 11:40 |
| xmz | tomreyn: OK, I'll try the new version, hope it solves it. thanks! | 11:52 |
| tomreyn | xmz: also make sure your kernel image is not compressed | 12:02 |
| tomreyn | generally, if the custom kernel is not in the right format, it will likely fail to boot with 20.04.1 as well (unless that comes with a newer uboot which supports more formats, but i assume it won't) | 12:03 |
| xmz | I'm not sure if the kernel compresses, I'm new to this. My steps to compile the kernel are: 1. Download the kernel source code 2. `cp /boot/config-xxxx .config `, and modify the optimization level option 3. make bindeb-pkg -j4 4. sudo dpkg -i *.deb . The same steps work fine under qemu x86 ubuntu, but qemu x86 ubuntu is booted with grub, not u-boot | 12:13 |
| tomreyn | running "file" on the kernel image will tell you what it is | 12:15 |
| xmz | Where is the kernel image, is it the one under /boot/? I tried it and this is the result: https://pastebin.ubuntu.com/p/vqGwDN5NPr/ | 12:20 |
| xmz | "gzip compressed data" ... | 12:21 |
| xmz | Ask how to compile the kernel in uncompressed format? Just like vmlinuz-5.15.0-1018-generic , since it boots fine, I really want the new kernel to boot | 12:25 |
| tomreyn | run gunzip on it? | 12:27 |
| tomreyn | xmz: ^ | 12:29 |
| xmz | Thanks, I am trying: # gunzip vmlinuz-5.15.53 | 12:32 |
| xmz | But it say gzip: vmlinuz-5.15.53: unknown suffix -- ignored | 12:32 |
| ogra | man gzip 😉 | 12:45 |
| ogra | (there are options to make it ignore the suffix) | 12:46 |
| xmz | Thanks. I try this and it works fine :`gzip -dc /boot/vmlinuz-5.15.53 | sudo dd of=/boot/vmlinuz-tmp` I'll try if I can boot it | 12:48 |
| xmz | It worked, thank you, tomreyn, ogra. amazing! | 12:53 |
| nominal_value | Hey all, anyone installing ubuntu server in hyperv? Do you have issues with installation not completing if you set a static IP in setup? | 16:10 |
| === ajfriesen6 is now known as ajfriesen | ||
| foo | This is more nginx-specific, but I'm having an issue where HTTP gets locked up... things hang... I can check for locked queries in postgres. Wondering what else I can do | 16:19 |
| foo | Not sure what's causing this | 16:19 |
| bryceh | anything in your log? | 16:25 |
| foo | bryceh: actually, I can tell from the graphs - HTTP gets locked up when we run out of memory. | 16:28 |
| foo | bryceh: next up: go into the logs and figure out what's eating up memory. | 16:29 |
| nominal_value | guys can someone help me with my netplan yaml? Trying to config a static ip for a new server vm | 17:34 |
| nominal_value | Copied and altered the yaml directly from netplan.io, and it still either gives errors or simply doesnt work | 17:34 |
| ahasenack | just a static ip? Have you checked the examples page at https://netplan.io/examples? | 17:34 |
| ahasenack | paste your yaml somewhere then | 17:34 |
| nominal_value | ahasenack: yes, see above. Pasted the config and altered for our network | 17:35 |
| ahasenack | sorry, I don't see the paste | 17:35 |
| nominal_value | https://pastebin.com/W14rxyMK | 17:38 |
| ahasenack | and what does "sudo netplan generate" say? | 17:38 |
| nominal_value | no i was saying that the above text is what i pasted into my .yaml file under the /etc/netplan dir. I altered it for our network | 17:38 |
| nominal_value | no output | 17:39 |
| ahasenack | do you have any other files in /etc/netplan, or just this one? | 17:39 |
| nominal_value | just this one | 17:39 |
| ahasenack | if there is no output, then it's syntatically correct | 17:39 |
| nominal_value | hm | 17:39 |
| ahasenack | have you tried "sudo netplan try"? | 17:39 |
| nominal_value | ok, dont crap on me for this........but if i didnt mention above, i am doing this as a VM under Hyperv. There is a blk error with many commands i make. It has been there since install earlier yesterday. Very strange and YES i know generally what that means | 17:41 |
| ahasenack | nominal_value: and, is your network interface called enp3s0? | 17:41 |
| nominal_value | so yes i did use netplan try | 17:41 |
| nominal_value | other than that output, there is none, and 'ip a' shows the correct ip | 17:42 |
| ahasenack | so what isn't working? | 17:42 |
| nominal_value | and no, my nic is eth0 | 17:42 |
| nominal_value | the network connection doesnt work at all | 17:42 |
| ahasenack | check if the routing is what you would expect: ip route | 17:43 |
| ahasenack | also double check netmask in the output of ip a | 17:43 |
| ahasenack | and have you tried with dhcp first, just to see if the networking is ok? Assuming there is a dhcp server provided by hyperv | 17:44 |
| nominal_value | yeah dhcp is fine | 17:44 |
| ahasenack | and the static ip you are using is within the same range as the one dhcp gave you in the previous test? | 17:44 |
| nominal_value | side note, i am running without X, so i only have terminal. How the heck do i copy out of terminal from there? | 17:44 |
| ahasenack | maybe this environment doesn't like random IP addresses coming up there, and only allows the ones provided by dhcp? | 17:45 |
| nominal_value | no, the static ip is in a completely different range, one that we we use for servers | 17:45 |
| ahasenack | doesn't look like it's a netplan problem so far | 17:45 |
| nominal_value | im wondering if my subnet is wrong. hmm lemme check that | 17:45 |
| ahasenack | yeah, check subnet/netmask, routes | 17:46 |
| ahasenack | and then tcpdump away, see what's going on, how far is the traffic you send getting | 17:46 |
| nominal_value | ok changed to /16 subnet, which looks like was needed for our network, given our edge router sits there | 17:47 |
| nominal_value | so NOW i can ping back and forth between hosts | 17:47 |
| nominal_value | ie this host and others | 17:47 |
| nominal_value | still no internet tho | 17:47 |
| ahasenack | check "ip route", if you have a default route and if it's what you expect | 17:48 |
| sdeziel | nominal_value: the netplan config you pasted mentions `enp3s0` but later you said your nic is `eth0`... which is it (sorry if I missed it in the backlog)? | 17:51 |
| nominal_value | its eth0, as i said, i copied and simply altered the official config syntax for our network | 17:51 |
| nominal_value | so now i can ping back and forth by ip, but not name | 17:51 |
| sdeziel | ah, I see | 17:51 |
| nominal_value | so nameservers dont work for some reason | 17:52 |
| ahasenack | check "resolvesctl status" | 17:52 |
| ahasenack | if it has the nameserver and search domains you specified | 17:52 |
| ahasenack | sorry, typo there: "resolvectl status" | 17:52 |
| nominal_value | yes it is using our secondary dns server atm | 17:53 |
| nominal_value | i removed search domains to see if any effect | 17:53 |
| nominal_value | no change | 17:54 |
| nominal_value | ah ok, ping will not reach our gateway for some reason. Can ping all other hosts | 17:55 |
| nominal_value | well that is interesting | 17:56 |
| sdeziel | nominal_value: pasting your current netplan config, `ip ro`, `ip a` and `resolvectl status` would help understand the situation | 17:57 |
| nominal_value | ugh | 17:59 |
| nominal_value | typo | 17:59 |
| nominal_value | DG was incorrect LOL | 17:59 |
| nominal_value | ooooopsy | 17:59 |
| ahasenack | what would the world be like without typos | 18:00 |
| ahasenack | so much less fun | 18:00 |
| nominal_value | well.....i learned something!, so thats good :) | 18:00 |
| nominal_value | thx so much for help ahasenack | 18:00 |
