WARNINGSも無視してよい

ただ、ここでは今後のためにWARNINGに対処します。

2. WARNING対処

■ WARN 1: 実行中カーネルが古い (WARN: unexpected running and installed kernel ‘5.15.102-1-pve’.)
→ これは無視します

■ WARN 2 & 3: ブートローダー (GRUB EFI) の設定

UEFIモードで起動しているのに grub-efi-amd64 メタパッケージがインストールされていないことが問題のようです。以下のコマンドを実行してパッケージをインストールします。

# デフォルトだとgrub-efi-amd64パッケージが無いため、non-free-firmwareをsource.listに追加する
# 参考：https://forum.proxmox.com/threads/8-to-9-amd64-microcode-warning.169263/
echo 'grub-efi-amd64 grub2/force_efi_extra_removable boolean true' | debconf-set-selections -v -u
# インストール
apt install --reinstall grub-efi-amd64

■ WARN 4: CPUマイクロコードが未インストール

AMD CPU用のマイクロコード更新パッケージがインストールされていないようです。以下のコマンドを実行して追加インストールします。

sed -i.bak -E '/proxmox/!{/^deb .*bookworm/{/non-free-firmware/!s/$/ non-free-firmware/}}' /etc/apt/sources.list
apt install amd64-microcode
root@tk006:~# cat /etc/apt/sources.list

もう一度pve8to9 を実行して動作確認します。

pve8to9 --full

WARNINGが1つであればOK

= SUMMARY =

TOTAL:    42
PASSED:   35
SKIPPED:  6

ATTENTION: Please check the output for detailed information!

2. リポジトリを変更

リポジトリをbookworm(debian12)からtrixie(debian13)に書き換える

sed -i 's/bookworm/trixie/g' /etc/apt/sources.list

実行例：

root@tk005:~# cat /etc/apt/sources.list
deb http://ftp.jp.debian.org/debian bookworm main contrib non-free-firmware

deb http://ftp.jp.debian.org/debian bookworm-updates main contrib non-free-firmware

# security updates

deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

root@tk005:~# 
root@tk005:~# sed -i 's/bookworm/trixie/g' /etc/apt/sources.list
root@tk005:~# cat /etc/apt/sources.list
deb http://ftp.jp.debian.org/debian trixie main contrib non-free-firmware

deb http://ftp.jp.debian.org/debian trixie-updates main contrib non-free-firmware

# security updates
deb http://security.debian.org trixie-security main contrib non-free-firmware

deb http://download.proxmox.com/debian/pve trixie pve-no-subscription

root@tk005:~#

公式手順にはEnterprise Subscriptionの追加があるが、無償版の場合は行わない

3. 更新

apt update
apt dist-upgrade

インストールシーケンスと、様々な確認がはじまる。

4. 各種確認

ここが一番厄介で、公式によると様々な質問が発生するケースがあるらしい。
私の場合は以下の通り設定しました。

No

OK

Y

他参考：

  • /etc/issue: defaultのNを選択
  • /etc/lvm/lvm.conf: LVMに関して特別な変更をしていないので上書きのYを選択
  • /etc/ssh/sshd_config: 問い合わせが現れませんでした
  • /etc/default/grub: 新旧の差分を表示して確認したあと、上書きで問題ないと判断してYを選択
  • /etc/apt/sources.list.d/pve-enterprise.list: 上書きのYを選択 (No-Subscription向けリポジトリへの変更は後ほどPVEのGUIでも行えるため)

5. バージョン確認

root@tk006:~# pveversion
pve-manager/9.2.10/43df2e01f27a1a19 (running kernel: 5.15.102-1-pve)

以上！
