This is the same issue as: https://bugs.launchpad.net/ubuntu/+source/valgrind/+bug/1808508 ... where the fix was to manually path the Valgrind debug info lookup path, but this doesn't seem feasible for every application that might care about symbols. Better to put the symbols in the right place or set up symlinks to ensure that is the case? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875274 Title: usrmerge breaks perf symbol lookup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875274/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
