New here so sorry if this is in the wrong category.
Using the latest version of Raspberry Pi Imager I tried to install Octo on a 32GB Micro-SD (from a Linux system). Used ctrl-shift-x to enter SSID, pwd and region and it wrote just fine until the end where it complained that it can't write the startup file. Naturally it didn't boot into WLAN and also didn't use the changed SSH passwd.
Not that it stopped me as I edited the octopi-wpa-supplicant file and made the pwd change after logging in via SSH but it may be a bit of a problem for beginners.
What I would also suggest to add in the instructions on the download page is to recommend running sudo apt update and sudo apt upgrade as the image is naturally a bit outdated (had 160 upgrades to install)
System is running great and the best thing I did to my 3D printer!
