• Network and Repository Problems 🌐
• Disk and Partitioning Errors 💿
• Package Installation Failures 📦

🚨 Boot and Media Errors

USB Boot Problems

Error: “No bootable device found” or “Missing operating system”

Solutions:

# Verify USB creation (from another Linux system)
sudo dd if=alpine-standard-3.18.4-x86_64.iso of=/dev/sdX bs=4M status=progress

# Check USB boot order in BIOS/UEFI
# Enable USB boot priority
# Disable Secure Boot if necessary

# Alternative: Use Ventoy for multi-ISO USB
sudo ventoy2disk.sh -i /dev/sdX

ISO Verification Errors

Error: “Checksum mismatch” or “Corrupted installation media”

Solutions:

# Verify ISO integrity
sha256sum alpine-standard-3.18.4-x86_64.iso
# Compare with official checksum from Alpine website

# Re-download if corrupted
wget https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-standard-3.18.4-x86_64.iso

# Use different download method
curl -O https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-standard-3.18.4-x86_64.iso

🖥️ Hardware Compatibility Issues

Graphics Driver Problems

Error: “Cannot initialize display” or black screen during boot

Solutions:

# Boot with safe graphics mode
# At boot prompt, press Tab and add:
alpine nomodeset

# Or try VESA mode:
alpine vga=normal nomodeset

# For persistent fix after installation:
echo "nomodeset" >> /etc/default/grub
update-grub

Network Interface Detection

Error: “No network interfaces found” or “eth0 not detected”

Solutions:

# Check hardware detection
lspci | grep -i network
lsusb | grep -i network

# Load specific drivers manually
modprobe e1000e  # For Intel adapters
modprobe r8169   # For Realtek adapters
modprobe ath9k   # For Atheros wireless

# Check interface status
ip link show
ifconfig -a

Memory and CPU Issues

Error: “Kernel panic” or “Out of memory during installation”

Solutions:

# Check memory requirements (minimum 512MB recommended)
# Boot with memory test
memtest86+

# For low memory systems, use minimal installation
# Download alpine-virt instead of alpine-standard

# CPU compatibility check
cat /proc/cpuinfo
# Ensure x86_64 architecture support

🌐 Network and Repository Errors

DNS Resolution Problems

Error: “Cannot resolve repository URLs” or “DNS lookup failed”

Solutions:

# Configure DNS manually during installation
echo "nameserver 8.8.8.8" > /etc/resolv.conf
echo "nameserver 1.1.1.1" >> /etc/resolv.conf

# Test DNS resolution
nslookup dl-cdn.alpinelinux.org

# Alternative: Use direct IP addresses
# Edit /etc/apk/repositories with IP addresses

Repository Access Issues

Error: “Cannot fetch repository index” or “Connection timeout”

Solutions:

# Switch to different mirror
vi /etc/apk/repositories
# Replace with:
https://mirror.leaseweb.com/alpine/v3.18/main
https://mirror.leaseweb.com/alpine/v3.18/community

# Update package index
apk update

# Or use local mirror
setup-apkrepos -c

Proxy Configuration

Error: “Connection refused” in corporate environments

Solutions:

# Configure HTTP proxy
export http_proxy=http://proxy.company.com:8080
export https_proxy=http://proxy.company.com:8080

# For APK package manager
echo 'export http_proxy="http://proxy.company.com:8080"' >> /etc/profile
echo 'export https_proxy="http://proxy.company.com:8080"' >> /etc/profile

# Configure proxy for wget
echo "http_proxy = http://proxy.company.com:8080" >> /etc/wgetrc
echo "https_proxy = http://proxy.company.com:8080" >> /etc/wgetrc

💿 Disk and Partitioning Errors

Partition Table Issues

Error: “Cannot create partition table” or “Disk not found”

Solutions:

# Check disk detection
lsblk
fdisk -l

# Clear existing partition table
dd if=/dev/zero of=/dev/sdX bs=1M count=10

# Create new partition table
parted /dev/sdX mklabel gpt
# Or for BIOS systems:
parted /dev/sdX mklabel msdos

# Use alternative partitioning tools
cgdisk /dev/sdX  # For GPT
cfdisk /dev/sdX  # For MBR

UEFI Boot Problems

Error: “UEFI boot failed” or “No EFI system partition”

Solutions:

# Check UEFI mode
[ -d /sys/firmware/efi ] && echo "UEFI mode" || echo "BIOS mode"

# Create EFI system partition
parted /dev/sdX mkpart primary fat32 1MiB 512MiB
parted /dev/sdX set 1 esp on

# Format EFI partition
mkfs.vfat -F32 /dev/sdX1

# Mount and install bootloader
mount /dev/sdX1 /mnt/boot/efi
grub-install --target=x86_64-efi --efi-directory=/mnt/boot/efi

Encryption Setup Errors

Error: “LUKS encryption failed” or “Cannot unlock encrypted drive”

Solutions:

# Check cryptsetup availability
