Troubleshooting
The installer says no network
Packages are downloaded during install, so connect Ethernet or Wi-Fi
first. The installer checks that deb.debian.org is
reachable and warns you if it isn't.
The install stopped halfway
Run the installer again without rebooting the USB and choose to resume. See Install.
The installer refuses my disk
It won't use the disk you booted from or one with mounted partitions. Unmount them or choose another disk. It also needs 40 GB, or 80 GB for two profiles.
I forgot my passphrase
It can't be recovered. The disk is encrypted on purpose.
It won't boot, or GRUB is missing
See Recovery.
Wi-Fi doesn't work
Firmware for common Intel, Realtek, Broadcom and AMD chips is
included. If yours isn't, you may need to install its firmware package
with apt over Ethernet.
Report a bug
Tell us on the MAS Discord server. Include your MAS version, whether you used UEFI or BIOS, one or two profiles, your graphics card, and the last lines the installer printed. Running MAS Installer (terminal) shows that output.
