I installed Ubuntu 24.04 and compiled go 1.22.2 using go 1.20.14 for bootstrapping. all.bash ran into two errors. Investigating the second I changed into go/src/syscall and executed go test and run into the failure again.
Interestingly TestAmbientCaps is skipped because the exec returns operation not permitted.
What did you see happen?
~/go/src/syscall$ go test
CAP_SYS_TIME unexpectedly not in the effective capability mask
--- FAIL: TestAmbientCapsUserns (0.01s)
exec_linux_test.go:752: exit status 2
