[00:02] austinthetaco: what is your exact issue at this moment? [00:03] i did an update & upgrade, which broke my ability to ssh [00:03] austinthetaco: let me rephrase, what is not working? [00:03] i cannot ssh into the server [00:03] austinthetaco: you can't ssh to the machine? Can you ping it? [00:03] no [00:04] austinthetaco: does it have an ip address? [00:05] austinthetaco: ? [00:06] not sure [00:06] yup, but it looks like it changed? [00:06] austinthetaco: is this on your home network? [00:06] it is, but i had it setup for a static ip [00:06] austinthetaco: ok, it changed, did you try to ssh to the new ip address? [00:07] i'm really confused why the ip address changed, it definitely has a static address [00:08] my hypervisor settings must be busted or something [00:08] :/ [00:08] hypervisor? [00:08] yeah, running the machine on an esxi guest [00:09] austinthetaco: this is really critical information that should be provided up front [00:11] i'll retry connecting via ssh once i get done fiddling with some vm settings [00:11] thanks === BrianG61UK_ is now known as BrianG61UK [01:11] Hi there. I have an odd problem. Trying to get a wifi dongle to work. It works fine in xubuntu, but not at all on lubuntu. What should I check? I did a modprobe on the lubuntu machine and yes, the ath9k module is there [01:12] blue1: rfkill list [01:13] does it show up in ip link output? [01:14] no, it shows ub in the lsusb though [01:14] sarnold: Bus 002 Device 002: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter [01:15] sarnold: it says soft blocked yes, hard blocked yes [01:15] rfkill unblock [01:15] rfkill unblock [01:15] thats the problem <3 [01:17] sarnold: okay that fixed the soft blocked but not the hard blocked [01:17] blue1: is there a switch on the machine? perhaps a bit of green on it? [01:19] blue1: could be blocked in the bios [01:19] ponyrider: there is no way to do any manipulation in the bios. it just shows up there and that's that. [01:19] ponyrider: any idea if a fn+f8 key toggles the 'soft' kill or the 'hard' kill? [01:20] sarnold: i know nothing of that [01:20] sarnold: no [01:20] sarnold: let me double check [01:21] blue1: are you *sure* the bios sint blocking it [01:22] blue1: actually sarnold has a point [01:22] ponyrider: I don't know that -- like I said the only thing there is something that shows the configuation. no way to manipulate it. It does have a wifi button but it is orange [01:23] blue1: yes what he means is that there might be a function combination which is hardware blocking ur device ( if your on a lappy ) [01:23] where can I post a picture? [01:23] blue1: is it a laptop? [01:24] imgur.com is popular [01:25] try the orange button if you';ve got one ;) [01:25] we dont need a picture LOL [01:27] ponyrider: yes hp [01:27] sarnold: I did it won;t toggle on [01:28] Ubuntu18.04.3 I have two hard disk a 2.5 msata in my laptop the other a usb enclosure with 2.5 sata..When grub 2.02 boots it show only the distro's in my msata laptop disk..when I boot the serbent usb disk it shows the distro in the laptop disk and also the usb disck..How to i get te usb disk to only show the distro on it [01:28] no [01:28] you don't [01:30] sarnold: this is at least what it is: https://imgur.com/a/JHU8hpe [01:46] brb.. === zbenjamin is now known as Guest18829 === zbenjamin_ is now known as zbenjamin [02:43] Hi there folks [02:43] I have a question about the GNOME screen magnifier [02:43] Hello how are you? [02:43] I managed to get it to turn on with the gnome tweak tool, and I can zoom in and out with "Windows"+Alt+Plus and minus [02:44] however, the factor it zooms at is 100% which is way, way too much [02:44] how do I reduce that down to 25% or something else more sane? [02:44] I'm planing to setup a server that has some hard drives connected to it just to act as an in house file server. Am I better off to use a server version of ubuntu or just desktop? I will be limited to 32-bit as the computer I'm running it on can boot 6-bit software. [02:44] Guest_28: if it's just for you in your house then desktop's fine [02:45] BenMcLean thank you mate! [02:45] Guest_28: does it have enough memory to run a gui in addition to whatever other services you want? [02:46] I'm only going to be running webmin and smb. I think so yes as Ive been able to run windows quite well. [02:47] Guest_28: I think the only other slightly complicating factor is that desktop uses networkmanager by default, which will probably do dhcp by default. if you want a fixed IP address it might be easier to use server, which you can then configure with netplan's config files to have a fixed address (assuming you *also* pick an IP outside your dhcp server's range) [02:48] Yeah it has a IP that has been set to its macid on the DHCP service. [02:48] ah that should also work [02:49] BenMcLean: you might take a look into dconf-editor perhaps, alot of tweaks around on all gnome [02:49] lotuspsychje: i'm already in that [02:49] There's an option for changing how zoomed in it currently is, but not for changing how much the keyboard shortcut zooms it in or out [02:50] BenMcLean: ok, no other ideas then, dont use the magnifier much myself === Guest_28 is now known as waydeb [02:57] i started compiz and it messed my desktop up, whats' the keyboard shortcut to get a terminal to kill it with? [02:59] BenMcLean: compiz on gnome? [02:59] yeah [03:00] BenMcLean: wich ubuntu release are you on? [03:02] latest [03:03] does no one even use this magnifier? it's awful [03:05] BenMcLean: Try key combo ctl+alt+t . [03:06] i tried that and killing compiz screwed up the display so bad i couldn't even type anymore, ended up hard rebooting. [03:06] Just starting up the installer and on the last line it says "(initramfs) Unable to find a medium containing a live file system" any idea on how to fix it? [03:07] BenMcLean: compiz is normally a unity thing, can you explain what you did exactly to get compiz onto gnome [03:07] shrug i dunno, typed sudo apt-get install compiz at one point [03:07] BenMcLean: and when playing with compiz, you need to tweak around with compizconfig-settings-manager [03:08] i'm on gnome, compiz is for unity, so i uninstalled it now [03:08] BenMcLean: if you want to play compiz, unity style, consider installing unity desktop ontop ubuntu [03:09] apparently this is out of date? https://wiki.ubuntu.com/Accessibility/Reviews/gnome-mag [03:10] "just google it" on linux questions tends to yield lots of completely false and misleading information [03:10] BenMcLean: last edited 2010... yes [03:11] BenMcLean: we dont advice to just google things here [03:14] Imma reboot it and see if it wants to work [03:14] can anyone find out where the hell the Super + Alt + + and - keyboard shortcuts are set? [03:15] BenMcLean: hotkeys in gnome are under systemsettings/devices/keyboard [03:16] OK I found where they are [03:16] but how do I change what those commands mean [03:17] nope its done the same thing again... [03:17] er, i mean, i found in the GUI where I can change which keys activate the commands [03:17] but where can I find the commands [03:17] -+3 [03:17] sorry just rested on my keyboard aha [03:17] somewhere, that "Zoom In" has got to be mapped to some command that tells gnome-mag to set zoom factor to itself plus 1 [03:18] and I want to change the "plus 1" to "plus 0.25" so we aren't zooming in and out by the ridiculous 100% this magnifier has [03:20] Am I bet to re-write the flash media? [03:20] *best [03:20] i found this https://gitlab.gnome.org/GNOME/gnome-shell/blob/master/js/ui/magnifier.js#L853-865 [03:24] does anyone know where I'd even report issues with the gnome magnifier? === Napsterbater is now known as Guest10595 === Napsterbater_ is now known as Napsterbater [03:29] OK hope I found the right place. https://gitlab.gnome.org/GNOME/gnome-shell/issues/1778 [03:35] hello, the solution to this is simple, I think, but I dont know how to google it. I want to control a peripheral with python. When I run my script as admin it works fine. How can I access the peripheral without needing admin rights? libgpib: ibBoardOpen failed to open device file /dev/gpib0libgpib: Permission denied [03:37] what peripheral is it? [03:38] gry a usb to gpib adapter === Napsterbater_ is now known as Napsterbater [03:52] Ok nope it didnt help. [03:53] danes: Is there a mount point for the adapter - chown the mounted directory ? [03:56] Bashing-om I found the solution. I knew I had to add my user to a group, which I didnt know, but I just found a tutorial that showed me how [03:57] danes: :D === Napsterbater_ is now known as Napsterbater [05:18] Can someone explain the security issues involved with this new error message from apt-get? [05:18] E: Repository 'https://deb.torproject.org/torproject.org buster InRelease' changed its 'Suite' value from 'testing' to 'stable' [05:18] N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details. [05:20] Diagon: are you using ubuntu or debian? [05:21] Ubunu [05:21] 18.04 [05:22] Diagon: then you do not need to use the debian packages; instead see https://2019.www.torproject.org/docs/debian.html.en and select your ubuntu version in the select box [05:23] Diagon: this will have 'bionic' instead of 'buster' in the entry [05:23] Diagon: I believe you will need to modify your software sources, in the same way as you added this entry [05:24] Ah, ok. Let me do that ... back in a min. [05:26] I see, that tor project web page is not particularly clear. I took from that my needing to use the debian verison. [05:27] yes, i think the select box is well hidden === jje_ is now known as jje [05:34] gry - you have any idea what this means? I changed to bionic and am trying to reinstall tor because I had buster in there. I get this message: "Reinstallation of tor is not possible, it cannot be downloaded." [05:34] remove it first. then try to install [05:35] Ok. ... (drop-down? I'm not finding a drop down at that link you sent.) [05:36] The way I read that page, I needed to find the debian equivalent for ubuntu: [05:36] sources.list: You'll need to set up our package repository before you can fetch Tor. First, you need to figure out the name of your distribution. A quick command to run is lsb_release -c or cat /etc/debian_version. If in doubt about your Debian version, check the Debian website. For Ubuntu, ask Wikipedia.

[05:53] hey y'all, I'm running Ubuntu19XX as a virtual machine on win10 surface pro 6 and I have all facilities including touch and mic but for some reason I cannot get the video camera to work. Any idea where I can get the drivers === Dewin|znc is now known as Dewin === Researcher-- is now known as Researcher- === deepend_ is now known as deepend [06:09] in_cognito: this depends on a couple things: driver support (which is most of a time just a m,atter of works-out-of-the-box or will-not-work-at-all), but less so, and rather whether the virtualization you're using can handle this video stream (possibly with hardware based "3d"/opengl graphics acceleration) and whether the VM is configured to use it (and maybe has extra drivers installed to pass its ourput through a virtual graphics device which [06:09] the virtualization provides and can handle well) === The_Milkman1 is now known as The_Milkman === Kira is now known as k_sze [06:49] hy, anyone have a lenovo t530 ?its wor [06:50] its ok to put a msata ssd the speed is ok [06:51] amadews: hi there. this looks like a ##hardware question to me. [06:51] tomreyn thanks man. That kind of suks. you'd think that camera drivers in 19.XX would be generally available. I'm still not sure where I could find the drivers, and if I did, which folder to put them in. [06:52] in_cognito: do you do usb passthrough there then? which virtualization is it? [06:56] !YY.MM | in_cognito [06:56] in_cognito: Ubuntu version numbers are: YY.MM (YY=release year,MM=release month). Each year sees two releases, so just specifying YY is imprecise. See also https://www.ubuntu.com/about/release-cycle [06:57] in_cognito: if it's usb passthrough, "lsusb" should list what was detected [07:06] guys anyone know why chromium doesn't open the torrents magnet links? [07:06] i got the pop up window with xdg-open message but nothing happens [07:17] hi all-curiousity has got the best of me on Ubuntu i use a vpn service i have found two ways to setup a connection one is from the terminal the other is using GUI (settings>network>vpn>"+"---I was wondering are the gui and the terminal carrying out the same commands essentially and are both using openvpn (my vpn is a paid service i have a username and password that i enter) [07:19] https://imgur.com/a/2bH8mT0 [07:19] here is an image of what i do to connect [07:20] eg GUI and sudo openvpn--config *****.ovpn [07:22] You can use OpenVPN with GUI. And if you do then it's just the same as in console mode. [07:23] tommy``: works on my 18.04 system, tested with https://jsfiddle.net/Ldry4kgb/ - what are you running? [07:23] tomreyn: 18.04.03 LTS [07:24] what commands are going on beneath the surface when you use the GUI to import a config file to make a vpn connection [07:24] tomreyn: if i click on the Download text the pop up windows appears but the .torrent doesn't start on transmission === Grldfrdom_ is now known as Grldfrdom === Grldfrdom is now known as Grldfrdom_ [07:28] thisguylost, If you wanna know in detail you gotta check the source code...most likely the file is copied in some place then it probably just run openvpn like you do in console, you can check the process for that. [07:28] appreciate your answer champ thank you =) [07:30] tommy``: hmm, you'd need to fiddle with xdg-mime then, i think [07:31] tomreyn: you mean configure ? [07:31] query, install, set default, something along these lines. i've not done it myself, and am not even sure what the corresponding mime type is [07:33] tomreyn: https://unix.stackexchange.com/questions/75614/set-transmission-as-default-program-when-opening-magnet-links [07:35] tommy``: might work, though when i run "xdg-mime query x-scheme-handler/magnet" here on my 18.04.3 it tells me "xdg-mime: unknown query type 'x-scheme-handler/magnet'" and chrom ium is still able to handle those magnet: URIs [07:37] https://askubuntu.com/questions/122930/how-can-i-make-firefox-open-magnet-links-in-transmission is very similar [07:37] i got this too xdg-mime: unknown query type 'x-scheme-handler/magnet' [07:42] tomreyn: according your link i'm stuck to this step: The last command (grep) should return "application/x-bittorrent=deluge.desktop" and the other mime type for magnet. Otherwise, something went wrong (maybe the desktop file didn't exist?). [07:43] tommy``: i think you'd point this to the most likely existing .desktop file for transmission in your case [07:44] where i can find that .desktop? [07:45] dpkg -L transmission-gtk | grep -i desktop [07:45] ok i have /usr/share/applications/transmission-gtk.desktop [07:46] http://paste.ubuntu.com/p/fTbjcWm8x3/ [07:46] yes, that's the .desktop file for transmission which comes with the package, and is what makes transmission available in your gnome-shell menu [07:47] see line 76 [07:47] StartupNotify=true [07:48] line 77 MimeType=application/x-bittorrent;x-scheme-handler/magnet; [07:48] interesting , we have different line numbers, but yes, i meant the mimetype declaration [07:49] that line seems good, nothing strange === autra_ is now known as autra [07:51] right, and once this software is installed and xdg-desktop -menu is aware of it (which the installation scripts should automate) then xdg-open should already know how to open this url handler [07:51] so i'm still unsure why it doesn't work for you. but also not really able to help more. [07:53] mmmmh [07:53] could be some settings on my local bash? [07:54] i have /.local/share/applications/mimeapp.list [07:54] this file is empty [07:54] Hello friends, I am seeing 500 errors when updating my repos. Just wanted to check if I am alone in thos (?)

[07:56] Hello! haha, my chance - I don't get the relation between cron and anacron. In /etc/crontab there is e.g. : 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) - which means that if there is anacron installed, then nothing happens here, right? If so, then *what* starts anacron and makes it to read and execute the /etc/anacrontab? [07:58] what's that? !? [07:58] really sorry guys [07:58] I found out what it was [07:59] I had disabled squid and clam services in my router/fw - this apparently borked things up [07:59] konrados: see ' cat /etc/crontab ' anacron is activated there. === The_Milkman1 is now known as The_Milkman [08:01] Bashing-om, but... where, here is my whole /etc/crontab : https://paste.gg/p/anonymous/085f049203324c56977b16713100b04b [08:01] wait... what does `test -x do` I thought it tests file is executable? No? [08:01] sec... [08:02] it only tests, it doesn't start it. [08:03] So how does that work? === peter-bittner1 is now known as peter-bittner [08:05] konrados: Test if exist and (||) then "run-parts --report /etc/cron.daily". [08:07] Bashing-om, my bash is pretty bad but - doesn't that mean the opposite? I tried that in terminal: `test -x /usr/sbin/anacron || echo 'e'` and since the amacron does exist, result is ok (0) the 'echo' was not executed.... [08:07] What am I misunderstanding? [08:07] || is or && is and. [08:08] And it short-circuits, so false && (never executed) returns false and true || (never executed) returns true. [08:08] tomreyn: i made some test, i launched from terminal the command xdg-open and transmission opened and get the torrent [08:08] that is very strange [08:09] yes, jink I know, and it is the `true || (never executed) ` because i *do* have anacron, the first condition is TRUE. [08:11] negative, the torrent is not added correctly on transmission [08:11] pleeease, what am I missing.... :( [08:19] konrados: you're just looking at the wrong file. /etc/cron.d/anacron is what starts anacron [08:20] tomreyn, thanks, but what starts '/etc/cron.d/anacron'? I tried to find info about it, but.. I only found that... it "works" - here : https://unix.stackexchange.com/questions/458713/how-are-files-under-etc-cron-d-used [08:20] tomreyn, I meant - what starts /etc/cron.d [08:20] the cron daemon [08:21] yes, but where is this defined? [08:21] in the source code of the cron daemon [08:21] It should be defined somewhere, in some file, right? [08:21] ahhhhh [08:22] haha, I would never think about that... geeee I thought all of this needs to be defined in some config files :) [08:22] tomreyn, - thank you! [08:22] glad i could help ;) [08:22] :) [08:23] I spent 2h on this o.O Time for a coffee:) [08:25] tomreyn: is possible to log what happens between chromium and transmission?

Im having an error with Ubuntu, specifically with the program Pinta [14:52] I'm a bit new to ubuntu, and I dont understand the error log that I'm getting or how to begin to "troubleshoot" the issie [14:52] issue [15:08] skilla, what error ? [15:08] I'm not sure what you mean by "what error" [15:08] When i run pinto through the CMD [15:08] pinta [15:08] it crashe swand outputs a big log [15:08] it doesnt have a specific "error name" i suppose [15:09] skilla, 'Im having an error with Ubuntu, specifically w ...' [15:09] yeah [15:09] it crashes [15:09] https://bugs.launchpad.net/pinta/+bug/1786822 [15:09] Launchpad bug 1786822 in Ubuntu "Pinta constantly crashes in Ubuntu 18.04 fresh install" [Undecided,Confirmed] [15:09] I can recreate the errors with ease [15:09] skilla, check #4 [15:09] what a pro [15:10] You know, I read about launchpad too and thought. Nah it wont have my issue [15:17] yo you guys playing albion === steven- is now known as steven === SimonNL is now known as SimonNL_Afk === Anon is now known as Anon0011 === Anon0011 is now known as _Unknown_ === freedom is now known as gnufr33d0m === med is now known as medberry [16:35] Hi! I'm on Ubuntu 18.04 and am trying to set up dynamic wallpaper (akin to mac os mojave). There's a gist for it: https://gist.github.com/thelcrysis/7c3563352de9b3467015fb0b3ceb184d [16:35] I've set up the paths correctly and yet, all I get is a blue background [16:35] any ideas what's wrong or how to debug this? [16:41] nvm, reboot fixed it [16:54] MapMan: some changes will only become apparent when the relevant processes have been restarted. a full reboot may not be necessary. [16:59] Hi, any idea how to find the exact version of libstdc++6-dbg for apt-get? [16:59] ofir, you mean the exact version that would be installed? [17:00] I mean the one that matches the currently installed libstd++-6 on my Ubuntu [17:00] there are multiple minor version candidates, but I'm not sure which one I have installed. [17:01] dpkg -l [17:02] If the package is virtual, you'll need to get the name of the real package it refers to [17:02] 8.3.0-6ubuntu1~ [17:02] (the Ubuntu 18.04 is a Docker installation BTW if that is relevant) [17:04] apt list --installed libstdc++6; apt search 'libstdc++.*-dbg$' [17:05] libstdc++6/bionic-updates,bionic-security,now 8.3.0-6ubuntu1~18.04.1 amd64 [installed] [17:05] so probably this one? libstdc++6-8-dbg/bionic-updates [17:06] probably :) [17:07] 10x, I still get corrupted stack trace in gdb :| [17:07] #0 0x0000000000000000 in ?? () [17:07] followed by: #1 0x00007ffff78fe925 in __gthread_create (__args=, [17:07] damn [17:08] and you're doing what exactly? [17:08] I'm pressing Ctrl Alt F1 on Eoan but it won't switch off the X11 display manager. Did something change? [17:09] !tty | jerichowasahoax [17:09] jerichowasahoax: To get to the TTY terminals 3-6, use the keystroke Ctrl + Alt + F3-F6 respectively. Ctrl-Alt-F2 or Ctrl-Alt-F1 will get you back to your graphical login (Ctrl-Alt-F7 on 16.04). To change TTY resolution, see https://help.ubuntu.com/community/ChangeTTYResolution [17:09] !ubuntu+1 | jerichowasahoax [17:09] jerichowasahoax: Eoan Ermine is the codename for Ubuntu 19.10 - Support only in #ubuntu+1 [17:09] oh, F1 is the display session, I wanted F2 [17:10] lotuspsychje, tomreyn: thank you [17:10] tomreyn: I have a crash when starting a C++ std::thread, it happens only on my Docker, never on my dev machine [17:10] it's a very trivial void function but unfortunately it never reproduces on a standalone reproducer (main.cpp with std::thread(foo)) [17:11] I have lots of shared libraries loaded and at some point in time when a thread is spawned, it stops working [17:13] ofir: hmm if it doesn't happen on a standard ubuntu installation then i'd blame your docker images [17:13] question is where do you even start.. [17:13] https://hub.docker.com/r/amd64/ubuntu/ are probably the most 'official' ones [17:14] I have the Dockerfile and everything but I'm not sure what I should be looking for [17:14] i'm not enough into docker to tell [17:16] see "Where to get help" on the page i linked [17:16] docker pull nginx to pull images from NGINX If I understand docker which I dont use === SimonNL_Afk is now known as SimonNL [17:18] or docker search nginx [17:19] ofir, https://www.linux.com/tutorials/how-install-and-use-docker-linux/ [17:19] thanks man, I know how to use Docker I'm just not sure where the shared libraries incompatiblity comes from [17:20] ofir, ok then sorry, I must have come in late to the conversation [17:20] ofir, you compile it with -pthread right? [17:20] doug16k: yeap [17:21] it could be that some shared libs are linked with static glibc/libstdc++ whereas others use a dynamic version [17:21] ok, I've seen toolchains which just screw up at runtime if you omit that, instead of refusing to link [17:21] that'd be my only guess [17:21] mine wouldn't let me build it if I don't pass the -pthread [17:24] ofir, what do you mean exactly by "it stops working" [17:24] How can I make the kernel unmount a mount when there is a permissions error ? I have a CIFS mount which when the user changes the password on the Active Directory, instead of unmounting, the cifs drivers keeps trying to login with the old password (even if the user it not currently on the computer) , and locking the user from the Active Directory, [17:24] ideas ? [17:25] starting to think it is simply multithreaded code bugs, and you only see the bug on vm because timing is drastically changed [17:25] doug16k: I mean the call to __gthread_create() crashes the process (SIGSEGV) [17:26] I'd see what valgrind says [17:27] hi [17:27] welcome theos [17:28] i get "segmentation fault(core dumped)" when i issue the apt command [17:28] Did you look at the core? :) [17:28] how do i look at the core? :) [17:29] Can you repeatedly make apt segfault? [17:29] yes [17:29] Do you have gdb on your system? [17:29] ofir, also try building with -fsanitize=thread [17:29] run strace -ff and look what happens before it [17:29] strace -ff apt... [17:29] no gdb [17:30] theos: install strace [17:30] ofir, also, try -fsanitize=address [17:30] ohh, if you can't d/l the .deb and install it manually maybe :/ [17:30] theos: Could you install that? [17:30] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x2912d248} --- [17:30] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x2912d248} --- [17:30] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x2912d248} --- [17:30] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x2912d248} --- [17:30] +++ killed by SIGSEGV (core dumped) +++ [17:30] Segmentation fault (core dumped) [17:31] and, as the /topic states, use a pastebin [17:32] sorry. i didnt see anything pasted in the xchat window [17:32] @doug16k: I will try it thanks, valgrind says PC jumped to 0x0 [17:32] ofir, and -fsanitize=undefined :D [17:32] which is as useful as gdb [17:32] unless I start debugging the assembly of libstdc++ I wouldn't be able to find out what happened [17:32] ofir: I mean if that's what the program is doing, that's what it's doing. [17:32] ikanobori i have strace installed thankfully [17:33] ikanobori: but that's not what I did :) [17:33] I highly recommend all the sanitizers [17:33] it is almost certainly that program's fault [17:33] accept that and you will have a good chance of actually finding the problem [17:33] I just started an innocent std::thread, it's the inner implementation that failed somewhere [17:33] theos: I don't specifically know how strace will help debugging a segfault :) [17:33] theos: which ubuntu version is this? does apt-get also segfault? [17:33] ofir: what is the issue ? [17:33] I'm willing to accept anything [17:34] linuxusr: on my Ubuntu 18.04 dev x86-64 machine I can spawn an std::thread, and on my Docker I get a segfault [17:34] tomreyn lubuntu 18.04. yes. apt-get also segfaults. aptitude is not installed. [17:34] segv means that the program tried to touch memory it's not allowed to, strace will show you which syscalls were calld which is likely not hte issue. [17:34] just running apt/apt-get without any arguments gives a segfault [17:34] theos: what were you doing before apt / apt-get started to segfault? [17:34] hence i tried to get you to install gdb and look at the corefile or run apt through it so we can see a bit more :) [17:34] ofir: do you load dynamic libraries in your code ? [17:34] I do [17:35] they might be loading their own instance of libstdc++ which might cause tons of issues [17:35] does any of your code or libs use static linking ? [17:36] it's a good question, that's gonna be my next step [17:36] you can check with 'ldd' on your binaries / .sos [17:36] I have 25 shared libs loaded [17:36]
