While attempting to fix the intermittent dns lookup error downloading from tooltool, I upgraded the Bitbar docker containers to Ubuntu 18.04. Though that alone did not fix the issue, I left the containers at 18.04. There was a problem with 18.04 and minidump_stackwalk however. minidump_stackwalk requires libcurl3 but that is incompatible with a simultaneous install of libcurl4. I tried to work around it during the image creation by first installing libcurl3 and copying libcurl3.so to a LD_LIBRARY path in the home directory and setting LD_LIBRARY_PATH to that directory in the .bashrc. However when minidump_stackwalk is invoked it fails to run with an /builds/worker/workspace/build/linux64-minidump_stackwalk: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by /builds/worker/workspace/build/linux64-minidump_stackwalk) error. I can either downgrade to Ubuntu 16.04 or do something else. Ted: I was wondering, since you did the work to build minidump_stackwalk in taskcluster, if it were possible to statically link libcurl3 into the binary so I could use minidump_stackwalk on Ubuntu 18.04 without worrying about libcurl3?

It might be possible but I don't think I've tried it. FWIW the script I used to build those binaries is here: https://dxr.mozilla.org/mozilla-central/source/taskcluster/scripts/misc/minidump_stackwalk.sh The Dockerfile to build the Docker image that it was built in is in this repo: https://github.com/luser/breakpad-taskcluster

Since 18.04 was the release we were looking for, I think I'll revert to 16.04 and move on. Thanks.

ack- this makes it hard to upgrade our linux testers, something to watch out for.

s/Since 18.04 was/Since 18.04 wasn't/ Yeah, but if you upgrade the builders at the same time, it shouldn't be problem.

Back to 16.04.
