Download speed of updates

How do I limit the download speed of updates on Blufin? It's taking up too much of my line.

I do not know of a single Bluefin setting that reliably caps update downloads to "X MB/s" across every update path. Because Bluefin updates can involve both the OS image and apps, it helps to split the problem into two likely sources: the system image update path (ujust update / bootc upgrade) and Flatpak app updates (flatpak update or Bazaar).

If you are not sure which one is filling the line, these checks should separate them:

bootc status
systemctl list-timers | grep -Ei 'update|bootc|rpm|flatpak|ublue'
flatpak remotes

If the system image update is the heavy one, the practical workaround is usually to schedule it rather than throttle it: turn off the automatic update timer you find in systemctl list-timers, then run ujust update or bootc upgrade manually when the connection is idle. If you need an actual bandwidth cap, router/SQM/QoS is cleaner than trying to wrap the update command, because automatic updates may run from a system service rather than your shell.

If Flatpak/Bazaar updates are the heavy part, handle those separately with manual flatpak update runs. Flatpak also does not give you a nice per-update bandwidth limit in the normal command path.

A local Linux traffic-shaping tool can work, but it will usually cap the whole interface or require more fragile per-process rules. For most Bluefin installs, scheduling updates or applying a router-side limit is the cleaner path.

If that distinction points you in the right direction, please mark the reply as answered so others looking for update bandwidth limits can find it.

AI advised setting the connection as "Metered Connection". Updates will then not be downloaded automatically.
