[Bug 1508081] Re: Fails to receive OTA updates

 

It'd be useful if we could get the full system ubuntu-download-manager
log next time this happens from /var/log/ubuntu-download-manager/ (not
the user log from .cache/ubuntu-download-manager).

In attempting to reproduce this I was able to on one occasion get the
system into a state where download manager permanently believed that the
network connection was "gsm" even when connected to wifi (and since the
system image download settings prevent download over gsm it caused the
downloads to be permanently queued), so this may be what's happening
here. I haven't been able to reproduce it since however, so it'd be good
to see the logs next time this occurs for someone else and see if the
same has happened.

  Fails to receive OTA updates

Status in ubuntu-download-manager package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu Touch 15.04 (r23) [mako]

  Issue: Phone appears to fail to receive OTA updates. Previously, I jumped from (r15) to (r23) due to missing OTA updates. Currently, I see (r24) appears to be released on 2015 Oct 16.
  Expected behavior: System Settings > System > Updates (or System Settings > About this phone > Check for updates) reveals new image that I can release and download.
  Actual behavior: Checking for updates... > Software is up to date

  See the comment regarding similar issues for large app installs.
  It seems if anything interrupts the transfer or if the connection is somewhat slow the download performance degenerates then times out.
