Public bug reported:
Focal has 4.26-0.2ubuntu3 which FTBFs and fixing it would require either
disabling many tests or picking many upstream commits.
Please accept new upstream realease 5.5 already packaged in Debian
instead.
The proposed package is tested in Bileto and there are no unfixed regressions compared to the results of the latest tests (some systemd tests are still running):

I've also rebuilt reverese build dependencies:

The only build failure are on riscv64.

releases.
Noteworthy changes in release 5.2 (2019-07-12)
==============================================
* Improvements
* Implemented syscall return status filtering with -e status=set option
and its aliases: -z (limit syscall printing to successful syscalls only)
and -Z (limit syscall printing to failed syscalls only). Addresses Debian
bug #176376.
* Implemented decoding of open_tree, move_mount, fsopen, fsconfig, fsmount,

syscalls.
* Enhanced decoding of bpf syscall.
* Wired up getegid, geteuid, getppid, io_pgetevents, statfs64, and fstatfs64
syscalls on alpha.

* Updated lists of ioctl commands from Linux 5.1.
Noteworthy changes in release 5.0 (2019-03-19)
==============================================
* Changes in behavior
* -D option now implies -I4: by default strace ignores SIGHUP, SIGINT,
SIGQUIT, SIGPIPE, SIGTERM, SIGTTIN, SIGTTOU, and SIGTSTP when -D option
is used.
* Diagnostic message is no longer printed if an attempt to restart a process
has failed with ESRCH. (Addresses RHBZ bug #1662936.)
* ASCII dump no longer tries to read the whole buffer at once. As result,
it can fail with a diagnostic message after dumping only a part.
Amount of preceding zeroes printed for offset is now chosen in a way
to accommodate all the digits of all the offsets being printed.
* Improvements
* Changed the way tracees are handled: all pending tracees are now waited for
before further processing, this improves fairness of tracee processing.
(Addresses RHBZ bugs #478419, #526740, #851457, #1609318, #1610774,
and maybe some others.)
* Enhanced xlat styles support configured by -X option.
* Enhanced decoding of bpf syscall.
* Enhanced decoding of PTRACE_PEEKUSER and PTRACE_POKEUSER on hppa.
* Enhanced pid formatting in strace-log-merge output.
* Wired up kexec_file_load and rseq syscalls on aarch64, arc, metag, nios2,
or1k, riscv, and tile architectures.
* Updated lists of BPF_*, BTRFS_*, FAN_*, IFLA_*, KERN_*, KVM_CAP_*, NDA_*,
NETNSA_*, NT_*, PR_*, REL_*, SECCOMP_*, SCTP_*, UDP_*, V4L2_*, and *_MAGIC
constants.
* Updated lists of ioctl commands from Linux 5.0.
* Bug fixes
* Fixed ordering of sockaddr_in6 fields.
* Fixed strace-k test on alpha.
* Fixed build on mips o32.
* Fixed build on NOMMU architectures.
* Fixed build in --with-libiberty=yes mode.
* Fixed potential NULL dereference during printing of line continuation
for syscalls that haven't been decoded.
* Fixed strace-log-merge error diagnostics.

Title:
[FFe] Please accept strace 5.5-3ubuntu1 to Focal
Status in strace package in Ubuntu:
New
Bug description:
Focal has 4.26-0.2ubuntu3 which FTBFs and fixing it would require
either disabling many tests or picking many upstream commits.
Please accept new upstream realease 5.5 already packaged in Debian
instead.
The proposed package is tested in Bileto and there are no unfixed regressions compared to the results of the latest tests (some systemd tests are still running):
https://bileto.ubuntu.com/#/ticket/4019
https://bileto.ubuntu.com/excuses/4019/focal.html
I've also rebuilt reverese build dependencies:
https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3203/+packages
The only build failure are on riscv64.

==============================================
* Improvements
* Implemented -DD and -DDD options that move strace into a separate
process group and session, respectively.
* Enhanced seccomp-bpf tracee syscall filtering support by implementing
new "binary match" BPF program generation strategy and automatically
choosing the strategy that generates the shortest BPF program.

* Enhanced decoding of BPF_MAP_LOOKUP_ELEM bpf syscall command.
* Implemented PTP_CLOCK_GETCAPS2, PTP_EXTTS_REQUEST2, PTP_PEROUT_REQUEST2,

syscalls. Use --seccomp-bpf option to enable.

* Enhanced decoding of NETLINK_ROUTE protocol.
* Implemented decoding of UNIX_DIAG_UID netlink attribute.
* Implemented decoding of WDIOC_* ioctl commands.
* Enchanced syscall count statistics: overhead is now applied per-call,
added ability for sorting on errors field.
* Syscall delay injection and overhead values can now be supplied with
time measure unit suffix and provided in IEEE 754 floating point format.
* Updated lists of AUDIT_*, BPF_*, ETH_*, KEYCTL_*, KVM_*, MAP_*, SO_*, TCP_*, V4L2_*,
XDP_*, and *_MAGIC constants.
* Updated lists of ioctl commands from Linux 5.3.

nios2, or1k, riscv, s390, s390x, sparc, sparc64, and tile architectures
when PTRACE_GET_SYSCALL_INFO is in use.
* Fixed decoding of sockaddr_hci (AF_BLUETOOTH) addresses that lack
hci_channel field.
* Fixed evdev ioctl bitset decoding.
* Fixed tests on alpha with Linux kernel headers 5.1+.
* Portability
* Removed support for decoding syscalls in range [1024...1079] on AArch64
architecture as this range has never been implemented in mainline kernel
releases.

and its aliases: -z (limit syscall printing to successful syscalls only)

Noteworthy changes in release 5.0 (2019-03-19)
==============================================
* Changes in behavior
* -D option now implies -I4: by default strace ignores SIGHUP, SIGINT,
SIGQUIT, SIGPIPE, SIGTERM, SIGTTIN, SIGTTOU, and SIGTSTP when -D option
is used.
* Diagnostic message is no longer printed if an attempt to restart a process
has failed with ESRCH. (Addresses RHBZ bug #1662936.)
* ASCII dump no longer tries to read the whole buffer at once. As result,
it can fail with a diagnostic message after dumping only a part.
Amount of preceding zeroes printed for offset is now chosen in a way
to accommodate all the digits of all the offsets being printed.
* Improvements
* Changed the way tracees are handled: all pending tracees are now waited for
before further processing, this improves fairness of tracee processing.
(Addresses RHBZ bugs #478419, #526740, #851457, #1609318, #1610774,
and maybe some others.)

constants.
* Updated lists of ioctl commands from Linux 5.0.
* Bug fixes
* Fixed ordering of sockaddr_in6 fields.
