Unable to launch playwright container in Ubuntu 24.04, some issue with kernel-level user namespaces

[kyle-sutherland]

OS: Kubuntu 24.04 LTS x86_64
Kernel: 6.8.0-36-generic
Slackdump 2.5.8 (commit: 8bcedfa)

I have tried running with multiple different options combinations (dump/export, tried every auth method) and I always get the following output (which seems to be raised by playwright, not slackdump since it is not captured but slackdump's log):

failed to initialise the auth provider: browser automation error: failed to launch: [launcher] Failed to get the debug url: [203489:203489:0630/125234.119635:FATAL:zygote_host_impl_linux.cc(127)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/main/docs/linux/suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox. #0 0x5e0af6f4a842 base::debug::CollectStackTrace() #1 0x5e0af6f371e3 base::debug::StackTrace::StackTrace() #2 0x5e0af6e88034 logging::LogMessage::~LogMessage() #3 0x5e0af565c3f6 content::ZygoteHostImpl::Init() #4 0x5e0af63dd572 content::ContentMainRunnerImpl::Initialize() #5 0x5e0af63db047 content::RunContentProcess() #6 0x5e0af63db3b6 content::ContentMain() #7 0x5e0af2afb309 ChromeMain #8 0x79602ea2a1ca (/usr/lib/x86_64-linux-gnu/libc.so.6+0x2a1c9) #9 0x79602ea2a28b __libc_start_main #10 0x5e0af2afb02a _start Crash keys: "switch-22" = "--user-data-dir=/tmp/rod/user-data/83f0cea555648198" "switch-21" = "--use-mock-keychain" "switch-20" = "--remote-debugging-port=0" "switch-19" = "--no-startup-window" "switch-18" = "--no-first-run" "switch-17" = "--metrics-recording-only" "switch-16" = "--force-color-profile=srgb" "switch-15" = "--enable-automation" "switch-14" = "--disable-sync" "switch-13" = "--disable-renderer-backgrounding" "switch-12" = "--disable-prompt-on-repost" "switch-11" = "--disable-popup-blocking" "switch-10" = "--disable-ipc-flooding-protection" "switch-9" = "--disable-hang-monitor" "switch-8" = "--disable-dev-shm-usage" "switch-7" = "--disable-default-apps" "switch-6" = "--disable-component-extensions-with-background-pages" "switch-5" = "--disable-client-side-phishing-detection" "switch-4" = "--disable-breakpad" "switch-3" = "--disable-backgrounding-occluded-windows" "switch-2" = "--disable-background-timer-throttling" "switch-1" = "--disable-background-networking" "num-switches" = "24" "commandline-disabled-feature-2" = "TranslateUI" "commandline-disabled-feature-1" = "site-per-process" "commandline-enabled-feature-2" = "NetworkServiceInProcess" "commandline-enabled-feature-1" = "NetworkService" "osarch" = "x86_64" "pid" = "203489" "ptype" = "browser"

I did some searching for possible solutions. The only suggestion I came accross was temporarily setting kernel.unpriveleged_userns_clone=1

and ensuring that user.max_user_namespaces has nonzero value.

I have set these switches and ensured that those values are correct, but the problem persists. Is there something that I'm missing here? Do I need to re-install, or install a kernel module? Is there a service that I need to restart in order for the kernel option value to take affect?

Another workaround I have considered is to locally fork the repo and add --no-sandbox argument to the function call that launches playwright, but I haven't tried that for 2 reasons:

1. I have never used go before, so I would be flying blind
2. Everything I have read says that running playwright/puppeteer this way is not safe.

Please help. I may also try just running the outdated windows version if all else fails.

I saw a discussion post only 2 days ago that had the same issue, but it seems to be gone now. Sorry if this is duplicate.
