rhansen suggested on IRC that this might be because of out of date dependencies in Debian, and I tend to agree.
Here's what I found: - golang-github-davecgh-go-spew-dev: up to date - golang-github-fatih-color-dev: 1.17 vs 1.18 upstream - golang-github-gosuri-uilive-dev: up to date - golang-github-gosuri-uiprogress-dev: ~git vs vs 0.0.1 upstream (7 years old!) - golang-github-kballard-go-shellquote-dev: "up to date" (no upstream release, seems dead) - golang-github-klauspost-pgzip-dev: up to date - golang-github-remeh-sizedwaitgroup-dev: ~git vs 1.0.0 upstream - golang-github-tidwall-gjson-dev: 1.17.0 vs 1.18.0 upstream - golang-github-tidwall-match-dev: 1.1.1 vs 1.2.0 upstream - golang-github-xorpaul-uiprogress-dev: should probably be removed, trivial changes from the the upstream - golang-golang-x-crypto-dev: 0.47 vs 0.48 upstream - golang-yaml.v2-dev: up to date Out of those, I think those are particularly critical: - golang-github-gosuri-uiprogress-dev: at least catch up with a release - golang-github-remeh-sizedwaitgroup-dev: same - golang-github-fatih-color-dev: small catchup - golang-github-tidwall-match-dev: small catchup Yet I looked at the changes on all of those, and nothing strikes me as possibly triggering the bug we have here.
