Restoring original system state
Note that if you Ctrl+C while it's downloading the upgrades, it gets the
keyboardinterrupt in the wrong spot - inside the progress handler and does not
restore the correct state, probably should be a different bug, though.

Bug description:
[Impact]
Calling update() or installing packages from apt clients resets their SIGINT
and SIGQUIT handlers to SIG_DFL, overriding any signal handlers they might have
set for them.
In case of ubuntu-release-upgrader, this results in the release
upgrader being unable to handle interrupts after it did the initial
update - the default libc handler will run and the program exits.
[Test plan]
[[apt]]
As a standalone test for apt, we can test the following script:
import apt
import time
apt.Cache().update()
print("WAITING")
try:
time.sleep(10000)
except BaseException as e:
print("Seen", repr(e))
print("END")
Pressing Ctrl+C while WAITING is printed should print Seen
KeyboardInterrupt, and importantly, also the END line.
[[ubuntu-release-upgrader]]
1) On an Ubuntu 18.04 system run do-release-upgrade in a terminal.
2) At the "Do you want to start the upgrade?" question say Y.
3) When you see the "Lock screen disabled" message you will also see
"Inhibiting until Ctrl+C is pressed".
4) Press "Ctrl+C"
Your /etc/apt/sources.list file will now have focal in it instead of
bionic although the upgrade has quit. With the version of ubuntu-
release-upgrader in -proposed you will not see the "Ctrl+C" message.
For your sources.list file to be restored you'll need the version of
apt from bionic-proposed installed before starting the upgrade.
[Where problems could occur]
apt: This specific change removes the two lines that SIG_DFL the signal
handlers after running scripts. AFAWCT those lines are unnecessary - the code
that calls it temporarily sets the handlers to SIG_IGN but restores previous
handlers at the end; it was wrongly refactored decades ago. A regression could
occur in that those signals will now continue to be ignored if we missed a spot.
ubuntu-release-upgrader: The change is wrapping a bunch of code in a
try: except: block so if the indentation was off the pyflakes /
pycodestyle tests would fail but autopkgtest will catch that.
[Original bug report]
As a long-time-user of ?ubuntu, with apt-get as tool of choice for
updates/upgrades I wrote a daily script for updates, with 'dist-upgrade'.
In all earlier years, it wouldn't actually do an upgrade of a ?ubuntu
version; just all packages including new ones. Version updates had to be
initiated manually, and I was always asked if I really wanted the new ?ubuntu
version. Sounds appropriate.
Last night when it (dist-upgrade), it just gave me 20.04. No questions asked.
I for one consider this kind of intrusive, though.
It *might* have to make with me trying 'sudo do-release-upgrade -m desktop' a
number of times earlier; just to *check* if the upgrade was on offer; but this
is only a guess.
In *any* case, a pop-up asking "Are you sure? Are you connected
through an adequate pipe? Are you sitting with full batteries; better
a power supply?" would be convenient; since I am using my PC for
urgent duties, and didn't want to fiddle with unexpected upgrade bugs.
