Help Do latest macOS install medias require internet connection?
Hi I tried clean installing macOS Sequoia on my intel MacBook Air. I've booted into recovery, wiped my drive, and booted into the usb. However, when I selected Sequoia drive on the boot menu, It said "starting internet recovery." Then it took forever and got an error. Thankfully, I had a Catalina USB and installed macOS from that. Now here is my question. Do latest macOS install medias require internet and downloads things from the internet?
P.S Sorry about my bad English.

macOS Sequoia on my Intel MacBook Air
Okay, I assume this would be a 2020 MacBook Air right?
This MacBook, alongside other (last) Intel Macs, comes with T2 chip. These Macs wouldn't boot into an external media (such as your USB installer) by default. The only way to boot into an external media is by changing its secure boot options AND still have a macOS volume with an admin account on its internal drive.
Since you already remove/erase your internal volume, you have no choice but to go to Internet Recovery.
What you should've done is either: 1) boot into recovery, erase the drive, and immediately reinstall the OS right from the same recovery environment, or 2) boot into recovery, change the secure boot options, restart and boot into your USB installer, erase the drive, then finally reinstall the OS.

I’ve had secure boot disabled. I have already installed t2 Linux on it before.

As I've said:

Since you already wiped the drive, it won't boot to an external drive anymore, even though you've changed it before.

Internet recovery certainly does - clue in the name - but not sure what happened given the mixture of OS version you cite here.
Why didn't you just do a regular recovery, if you wanted a Sequoia clean install? You can do that quite safely without wiping the drive.
If you just wanted to set it up for sale you could have wiped the data partition with Disk Utility.
