I don't think this is urgent; they're not test bots, so it's not like we're losing test results every hour they are turned off. Can deal with it next week IMO. 1983568 6 dpino 2023-10-08 08:24:13 -0700 FYI, an interruption of the WebKitGTK Ubuntu LTS build bot will likely cause an interruption of WebKit Search (https://searchfox.org/wubkat/source/) as well, because both bots build WebKitGTK with a similar configuration (--no-experimental-features plus a few features disabled). While the other bots are not critical, I think an interruption of WebKit Search is more important since many people use it daily. I searched for a libbacktrace package in Ubuntu and it doesn't seem to exist (neither 20.04 or 22.04). Libbakctrace is installed directly from a git repository (https://github.com/WebKit/WebKit/blob/main/Tools/buildstream/elements/sdk/libbacktrace.bst). A potential fix could be to install this package as a JHBuild dependency, but that wouldn't be enough for bots that do not use JHBuild and build only using system libraries (--no-experimental-features). In this case, those bots have to build with --USE_LIBBACKTRACE=OFF. I can change the bots settings to build with this flag disabled.
