Public bug reported:
I just noticed that do-release-upgrade did not properly handle a failure
of the http method:
Traceback (most recent call last):
File "/tmp/ubuntu-release-upgrader-1wz4x5y5/disco", line 8, in <module>
sys.exit(main())
File "/tmp/ubuntu-release-upgrader-1wz4x5y5/DistUpgrade/DistUpgradeMain.py",
line 238, in main
if app.run():
File
"/tmp/ubuntu-release-upgrader-1wz4x5y5/DistUpgrade/DistUpgradeController.py",
line 2033, in run
return self.fullUpgrade()
File
"/tmp/ubuntu-release-upgrader-1wz4x5y5/DistUpgrade/DistUpgradeController.py",
line 1949, in fullUpgrade
if not self.doDistUpgradeFetching():
File
"/tmp/ubuntu-release-upgrader-1wz4x5y5/DistUpgrade/DistUpgradeController.py",
line 1185, in doDistUpgradeFetching
self.cache._fetch_archives(self.fetcher, pm)
File "/usr/lib/python3/dist-packages/apt/cache.py", line 427, in

return self._run_fetcher(fetcher)
File "/usr/lib/python3/dist-packages/apt/cache.py", line 394, in _run_fetcher
res = fetcher.run()
apt_pkg.Error: E:Method http has died unexpectedly!, E:Sub-process http
received a segmentation fault.
Error in sys.excepthook:
Traceback (most recent call last):

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid

Original exception was:

File "/tmp/ubuntu-release-upgrader-1wz4x5y5/disco", line 8, in <module>
sys.exit(main())
File "/tmp/ubuntu-release-upgrader-1wz4x5y5/DistUpgrade/DistUpgradeMain.py",

if not self.doDistUpgradeFetching():

res = fetcher.run()
apt_pkg.Error: E:Method http has died unexpectedly!, E:Sub-process http

It now leaves me stuck:
# do-release-upgrade -d
