Thank you for making this bug report YunQiang! I unfortunately do not have a risc-v system to test this out on.
Was this ssh working before and it was a recent regression? Does the connection fail immediately or does it time out? I see we have a version of openssh in the -proposed pocket `1:9.6p1-3ubuntu13.5`, for picking up new build flags for ppc64/s390x. I'm curious if that update might also help for risc-v if you are willing to test out the proposed package. to see if you are still affected with the new package. ** Changed in: openssh (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/2077047 Title: riscv server: fail to login if compress is enabled by client Status in openssh package in Ubuntu: Incomplete Bug description: I have a RISC-V box, which has Noble installed, and the version of openssl-server is 1:9.6p1-3ubuntu13.4.
