Distro

  • Merged os-prober version 1.84 into Resolute (LP: #2133973)

lziprecover

  • Invalid relocations on riscv64 can be avoided with -mcmodel=medany -mexplicit-relocs. Waiting for PPA build. Upstream MR created. (LP: 2134476)

mayo

  • Build failure on riscv64 can be avoided by adding missing definitions from upstream fast_float. Waiting for PPA build. (LP: #2134548)

flash-kernel

  • Correct dtb file name for the StarFive VisionFive 2 Lite (LP: # 2132298)

aegisub

  • The build failure on riscv64 is caused by adding the upstream LuaJit to the source tree. We would have to use the RISC-V extended one from PCLT Labs for RISC-V support (LP: #2134595)

kamailio

  • GCC internal failure reported to upstream (LP: #2134383)

valentina

  • Adding alignment constraints should fix the build failure. Waiting for PPA build. (LP: #2134600)
