This just repeats. It never seems to work.

Blocked there indefinitely.

Can't open firefox file browser to upload / download files. Can't open fire system browser from desktop by clicking on app. Can't even ls /

This appears intermittently, maybe a race condition? A full restart will sometimes clear the issue.

FWIW, I'm on a ZFS filesystem, encrypted at boot, with some extra ecrypt folders mounted at login.

Same here with btrfs on a luks system. (LMDE6 Debian based)

jodavaho commented 8 months ago

Workaround: Killing keybase-redirector releases all blocked tasks.

ubuntu 22.04: sudo killall keybase-redirector

tuupola commented 7 months ago

Same here with Fedora with btrfs and luks. Running sudo killall keybase-redirector seems to fix the problem.

daithi-coombes commented 6 months ago

same here, ubuntu 22.04

Linux daithi 6.5.0-21-generic #21~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb  9 13:32:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Hanging when running apt-get update. Stack trace similar to op in dmesg. Noticed also file dialog in browsers (firefox and chromium) both stopped working last week. See it mentioned above, not sure if related?

Running sudo killall keybase-redirector unblocked keybase and apt-get update continued :+1:

Also, I've been having problems with this machine and file browser, ls and file dialog in browsers randomly not working for about a year. Restarting the machine fixes it.

Possibly the same as issue https://github.com/keybase/keybase-issues/issues/4256
