Client: UI not opening after update to 5.3.0-20200310205642+4f2689009b

[carroarmato0]

I updated Keybase through my package manager on Ubuntu 19.10, but now the UI seems to be crashing immediately when starting up.

I do have a crash report from the crash detection system on Ubuntu
_opt_keybase_Keybase.1000.crash.txt

[majk-p]

Same for me on Ubuntu 18.04:

$ /opt/keybase/Keybase

[heronhaye]

Thanks, we're looking into it.

[carroarmato0]

Thanks, we're looking into it.

If you need any info from me that could help with troubleshooting, let me know

[heronhaye]

@carroarmato0 What's your kernel version? uname -a

[carroarmato0]

@carroarmato0 What's your kernel version? uname -a

Linux neon-flower 5.3.0-40-generic #32-Ubuntu SMP Fri Jan 31 20:24:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

[heronhaye]

@majk-p how about you?

[majk-p]

The same:

[heronhaye]

I've tried both 18.04 on a 4.15 kernel and 19.10 on 5.3 (in virtual machines) and I can't reproduce the issue. Is there anything special about your systems I should know about?

[majk-p]

Nothing special. quite fresh system install. Keybase installed from https://prerelease.keybase.io/keybase_amd64.deb. Just tried installing nightly and then downgrading - with no luck.
Any cache/temp files we can remove maybe?

[carroarmato0]

Same here, nothing special.
Made an strace for fun if anyone can spot anything of interest.
keybase-strace.txt

I agree with @majk-p, I think it's probably some weird state after the upgrade, clearing some kind of cache might maybe solve this?

I have the same issues. The application will not open and simply crashes to the background process.

[heronhaye]

@majk-p @carroarmato0 shot in the dark, what glibc version do you have installed?

[carroarmato0]

@majk-p @carroarmato0 shot in the dark, what glibc version do you have installed?

➜ ~ ldd --version
ldd (Ubuntu GLIBC 2.30-0ubuntu2.1) 2.30

Good old default 2.30 shipped with Ubuntu

[heronhaye]

@carroarmato0 Are you a developer? Would you want to try building the Keybase GUI to help us debug it? Unfortunately I still cannot reproduce the issue.

If you do, you can clone https://github.com/keybase/client/, cd shared, and then run yarn modules and yarn start. Let me know if that crashes for you as well - it should connect to your keybase service if it's running.

Otherwise, I can't really do much with the coredump since it wasn't generated from a build with debug symbols. If you could reproduce it on a VM/vagrant box, that'd help me a lot in debugging.

[heronhaye]

Actually, another thing you could try is: download and install electron 8.0.2 with debug symbols from https://github.com/electron/electron/releases/download/v8.0.2/electron-v8.0.2-linux-x64-debug.zip, and run /path/to/that/electron/binary /opt/keybase/resources/app. If that crashes too, could you send another crash report?

This is weird, I redownloaded the electron release multiple times, but each time I tried to execute it I got a

➜  debug ./electron.debug 
zsh: exec format error: ./electron.debug
➜  debug file electron.debug 
electron.debug: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter *empty*, for GNU/Linux 3.2.0, BuildID[sha1]=6e608e0ace0d5785b97fb1a5769af07b9dec5e7e, with debug_info, not stripped

[carroarmato0]

This looks interesting though in 8.1.0, will give that one a try: https://github.com/electron/electron/pull/22481

[carroarmato0]

@heronhaye I'm not sure if I'm doing something wrong, but maybe I'm supposed to be calling electron through nodejs instead of executing it directly?

[heronhaye]

@carroarmato0 sorry for the bad instructions, I figured out how to load the debug symbols myself. It looks like it has something to do with your systray. What DE/WM are you using, and does it have a system tray?

[DaveLMSP]

I'm seeing the same issue on two machines running Linux Mint 19.3 with Mate desktop v1.22. They're running two different kernels which are copied below:
Machine1: 5.0.0-32-generic #34~18.04.2-Ubuntu SMP Thu Oct 10 10:36:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Machine2: 4.15.0-88-lowlatency #88-Ubuntu SMP PREEMPT Tue Feb 11 20:51:55 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

When I run keybase the main GUI opens, but the systray icon/menu stopped working with the most recent update.

[kstudent]

Same here:
Linux version 4.18.0-25-generic (buildd@lcy01-amd64-025) (gcc version 8.3.0 (Ubuntu 8.3.0-6ubuntu1~18.10.1)) #26-Ubuntu SMP Mon Jun 24 09:32:08 UTC 2019

[carroarmato0]

@heronhaye default in Ubuntu with Gnome Shell. I tried switching between xOrg and Wayland, but that doesn't change anything, so can be excluded.

[kg4zow]

If it helps, this version of the Keybase client works just fine under Tails 4.4.

[ricardobalk]

Possible solution was found in #23073. Just waiting for the release.

[heronhaye]

@carroarmato0 @majk-p @Currrupted @kstudent @kg4zow please try out the latest nightly at https://keybase.io/docs/linux-user-guide#nightly-builds and let me know if it fixes the issue for you. I'll update when the stable release is out. Thanks!

@DaveLMSP if the GUI opens fine but it's just the systray icon that's broken, that's known and due to a breaking change in upstream Chromium.

[carroarmato0]

@heronhaye it's working!

Wow, thanks a lot! I was able to open Keybase again and so far I haven't run into any issues! :heart:

Thank you, works great!

[heronhaye]

All right, we've released version 5.3.1 which should fix the issue. Please upgrade and let me know if it still doesn't work.

If you installed the nightly, you can downgrade to the release version (manually reinstall from https://keybase.io/docs/the_app/install_linux), or you can just stay on the nightly (you'll get an update for the next stable release when it comes out).
