So, I want to use arch linux but I've a very poor internet connection and I'm going to triple boot it with kali and windows.I'm worried about the updates.
My internet speed is about 112kbps
How often do arch updates occur?
The answer to this is:
As often as you choose to update.
But, to expand a little (from the Arch Wiki):
The user decides when to upgrade, and merges necessary changes when required. If the user reaches out to the community for help, it is often provided in a timely manner. The difference between Arch and other distributions in this regard is that Arch is truly a 'do-it-yourself' distribution; complaints of breakage are misguided and unproductive, since upstream changes are not the responsibility of Arch devs.
To summarize: you can have zero updates, or ten updates per day. It is entirely up to you!
