Debian10 Buster から Debian11 Bullseye にアップグレードする

Gemibookで、Debian11 Bullseyeにアップグレードした時の個人的な備忘録です。

updateとupgrade

sudo apt update
sudo apt upgrade

/etc/apt/sources.listを変更

sudo nano /etc/apt/sources.list

変更前

/etc/apt/sources.list

deb http://ftp.riken.jp/Linux/debian/debian/ buster main
deb-src http://ftp.riken.jp/Linux/debian/debian/ buster main

deb http://security.debian.org/debian-security buster/updates main
deb-src http://security.debian.org/debian-security buster/updates main

# buster-updates, previously known as 'volatile'
deb http://ftp.riken.jp/Linux/debian/debian/ buster-updates main
deb-src http://ftp.riken.jp/Linux/debian/debian/ buster-updates main

変更後

/etc/apt/sources.list

deb http://ftp.riken.jp/Linux/debian/debian/ bullseye main non-free
deb-src http://ftp.riken.jp/Linux/debian/debian/ bullseye main non-free

deb http://security.debian.org/debian-security bullseye-security main non-free
deb-src http://security.debian.org/debian-security bullseye-security main non-free

# buster-updates, previously known as 'volatile'
deb http://ftp.riken.jp/Linux/debian/debian/ bullseye-updates main non-free
deb-src http://ftp.riken.jp/Linux/debian/debian/ bullseye-updates main non-free

ついでに、non-freeに変更しています。

buster/updates は、bullseye-security に変更しないとダメらしい。
