+1 Maintenance report (August 25-29)

[Graham Inggs]

I started off the week using `retry-autopkgtest-regressions --blocks
<package>` to retry the autopkgtests blocking the following packages:
* python3-defaults
* qemu
* initramfs-tools
* dh-cargo

I looked through `update_excuses` and found several packages that were
FTBFS or failing autopkgtests, checked in Debian for similar bug
reports, used `import-bug-from-debian <bug #>` to import them into
Launchpad, then tagged them `update-excuse`, and `ftbfs` if needed.
