Error Tracker

• Fixed an API endpoint used by phased-updater: errors/api: set default limit to 0 · ubuntu/error-tracker@6b51426 · GitHub
• Fixed Launchpad integration
• Fixed some additional views:
  • retracers.js: use more sensible defaults · ubuntu/error-tracker@7ad1326 · GitHub
  • errors: repair /bucket/ view: remove extra '.encode()' · ubuntu/error-tracker@af82886 · GitHub
  • errors: repair /user/ view · ubuntu/error-tracker@fbdbdcb · GitHub
  • https://github.com/ubuntu/error-tracker/commit/6d6a594b80b11e18ab08b4b9495aaf8f69dbcf09
  • errors: repair and improve /user/ view · ubuntu/error-tracker@7381151 · GitHub
  • errors: remove redundant 'main' views · ubuntu/error-tracker@50c3888 · GitHub
• Monitored the whole week the staging phased-updater to check any difference against the production one. So far results are very encouraging, but I’ll still wait as long as possible before cutting-over.

cdimage

• Disabled Resolute dailies for MATE and Unity (Merge into main : skia/disable_resolute_flavors : lp:ubuntu-cdimage : Git : Code : Ubuntu CD Images)
