Since 2023-10-02, we have a fixed version of the curl package on stable-backports, so this can serve as a workaround if you're fine with the constraints of the backports repository[0].
The current investigation status is that we know which commit caused the regression and which one fixed it, but we don't know exactly what change in the fixing commit is required (it's changing a lot of things at once). We also don't know exactly what are the conditions that trigger the issue, but we know it has to do with HTTP2 and there are a couple of endpoints we can use for debugging. Regression commit: https://github.com/curl/curl/commit/8c762f59983a3e9e2b80fdb34aa5e08f1d9a1c7d (curl-7_88_0) Fixing commit: https://github.com/curl/curl/commit/744dcf22fac6cf12a9112df106b61864982afef9 (curl-8_1_0) [0]: https://backports.debian.org/ Cheers, -- Samuel Henrique <samueloph>
