| Guest42 | hello, my laptop recently randmoly stops charging when connected to power | 09:44 |
|---|---|---|
| Guest42 | has anyone come across this | 09:45 |
| Guest42 | is this something I can change in the ubuntu settings | 09:45 |
| tomreyn | Guest42: i'm afraid not. this is a pure firmware / hardware issue | 09:46 |
| tomreyn | ubuntu and the kernel do not manage charging (incl. whether or not it happens) in any way | 09:47 |
| Guest42 | ok | 09:49 |
| tomreyn | you could try a bios upgrade (or just look over its changelog as to whether there's anything related). but most likely this is really an issue with the battery, the power supply, or, best case, the wiring. | 09:49 |
| lotuspsychje | tnx | 09:50 |

| mrec | malicious USB devices are able to crash the latest ubuntu version | 13:26 |
| mrec | someone added a null pointer issue to the USB core | 13:26 |
| lotuspsychje | mrec: dont trust usb media thats not yours | 13:27 |
| pickanick | mrec: which ubuntu version ? | 13:27 |
| mrec | noble, 6.8.0-48-generic | 13:28 |
| mrec | if the usb device is defect it can cause a nullpointer issue | 13:28 |
| mrec | and crash the entire system | 13:28 |
| mrec | this was not the case in earlier linux versions | 13:28 |
| mrec | BUG: kernel NULL pointer dereference, address: 0000000000000020 | 13:30 |
| mrec | address 20 .. ya someone is accessing a member of a struct which is NULL | 13:30 |

| enyc | Hrrm; anybody with other 24.04 installs/variants, able to sudo apt install gscan2pdf and confirm gscan2pdf doesn't start/work ?? | 13:32 |
| enyc | I'm curious about underpinning packges/programs, which where library etc might be that with bugreport and so-on! | 13:33 |

| jluc | enyc it installs and launches well here | 13:35 |
| enyc | jluc: what ubuntu version? | 13:35 |
| jluc | 24.04 | 13:35 |
| enyc | jluc: OoOOooooOOOoO i wonder if there was a repaired bug! | 13:35 |
| jluc | 24.04.1 | 13:36 |
| jluc | and gscan2pdf 2.13.2 | 13:36 |
| enyc | jluc: thankyou, this is news to me, I will retry on (at least) a mint-22 ubuntu-24.04-based-system BUT if it doesn't work it'll encourage me to lok further, new 24.04 installs, etc as you've very helpfully told me it now can work for *some*. | 13:40 |
| leftyfb | mrec: got a CVE for this "exploit" | 13:50 |
| enyc | or indeed new ubuntu 24.04.1 install of some variant | 13:51 |
| enyc | jluc: is your system on which it works, new from 24.04, or upgraded from 22.04/23.10/etc ?? | 13:51 |
| jluc | brand new | 13:52 |
| leftyfb | enyc: please install ubuntu 24.0.4 to test yourself. We cannot support Ubuntu derivatives here. | 13:52 |
| enyc | leftyfb: not failiar with 24.0.4, I know as i said above, try on new 24.04 installs was already on my list. | 13:52 |
| mrec | leftyfb: if I got one? no I just experienced it because I'm testing assembled USB PCBs | 13:52 |
| leftyfb | mrec: feel free to file a bug | 13:53 |
| mrec | I'll fix it first. | 13:53 |
| leftyfb | mrec: you're going to patch the kernel and then submit a PR? You should do that upstream as well. And test later kernels | 13:54 |
| mrec | not a big deal, I'll check it within the next days. | 13:54 |
| leftyfb | mrec: "malicious USB devices are able to crash the latest ubuntu version" sounds like a pretty big deal to me | 13:56 |
| mrec | not only malicious .. defect usb devices | 13:56 |
| leftyfb | ok, then file a bug | 13:56 |
| lotuspsychje | mrec: maybe share your journal logs first? | 13:56 |
| mrec | I need to get my work done first.. | 13:57 |
| mrec | it doesn't seem to be a big deal the kernel is printing some issues that the device is not recognized, some debug is probably throwing the error | 13:57 |
| mrec | we manufacture USB devices and test each of them before shipping some of them are not ok after assembly and need to be repaired. | 13:58 |
| mrec | usually some cold solder joint somewhere. | 13:58 |
| mrec | in some rare cases. | 13:59 |
| lotuspsychje | lets see that in the logs | 13:59 |
| mrec | but a defect keyboard could cause the same problem | 13:59 |
| mrec | https://pastebin.com/h3BTbWF5 | 13:59 |
| leftyfb | mrec: and your entire machine "crashed" when you plugged it in? | 14:00 |
| mrec | a little bit after that nullpointer issue | 14:01 |
| mrec | like 1 minute later | 14:01 |
| leftyfb | as in, you had to forcefully power off and back on ? | 14:01 |
| mrec | the system completely crashed, everything stuck | 14:01 |
| leftyfb | mrec: and you replicated this 3 or more times? | 14:02 |
| mrec | including the mouse | 14:02 |
| mrec | I'll come back in 1-2 days and report further I'll check the kernel code shouldn't be difficult to spot that issue | 14:02 |
| leftyfb | no, file a bug | 14:02 |
| leftyfb | don't report bugs here | 14:02 |
| leftyfb | !bug | mrec | 14:03 |
| ubottu | mrec: If you find a bug in Ubuntu or any of its official !flavors, please report it using the command « ubuntu-bug <package> » - See https://help.ubuntu.com/community/ReportingBugs for other ways to report bugs. | 14:03 |

| kuka_lie | hello vardhan | 16:24 |
| vardhan | Hi kuka_lie, tomreyn | 16:30 |
| vardhan | Maybe Im in the wrong forum. I am getting weird firefox benaviour on kubuntu, where it has stopped downloading anything. It says it has no permissions though I have given chmod 777 on the download directory. | 16:30 |
| kuka_lie | does this happend with other browsers | 16:30 |
| vardhan | No. Edge works. | 16:30 |
| kuka_lie | just update firefox and see if it works | 16:30 |
| vardhan | OK. I had firefox snap and the ubuntu package running parallelly till recently. I had a few profiles on snap. One day all profiles got deleted (I tried to recover but could not yet). Now I am using the latesr FF I guess | 16:30 |

| tomreyn | vardhan: things you can try: (1) run firefox froma terminal emulator (such as konsole), try downloading something, see what's printed to the terminal emulator window. you may see critical firefox errors there. (2) create a new firefox profile and try downloading something. if it works there, something is wrong with your profiles' add-ons or preferences. (3) check that your disk has not run full, and that your file system is not corrupt. (4) run | 16:35 |
| tomreyn | journalctl -f in a terminal emulator and keep it running, then try downloading something in firefox, then see what was printed to screen on the terminal emulator. you may see system or service errorrs or warnings there, some of whidh may be related. | 16:35 |
