Ubuntu 19.10 amd64 環境でapt upgrade でエラーになります．
新しいKernel が降りてきてinitramfs のところでdm-crypy 領域が見つからない感じのようです．
initramfs-tools (0.133ubuntu9) のトリガを処理しています ... update-initramfs: Generating /boot/initrd.img-5.2.0-8-generic cryptsetup: ERROR: Couldn't resolve device /dev/disk/by-uuid/805938be-2c29-4a53-9ed2-36fb233d76ea cryptsetup: ERROR: Couldn't resolve device UUID=31145c5b-93fc-4fe0-9e46-3a68bfcadeae W: initramfs-tools configuration sets RESUME=UUID=31145c5b-93fc-4fe0-9e46-3a68bfcadeae W: but no matching swap device is available. 処理中にエラーが発生しました:
エラーメッセージで検索すると以下のページを発見．
The problem is that cryptsetup is not supported in the /etc/initramfs-tools/initramfs.conf configuration anymore.
The new location for loading dm-crypt during boot is /etc/cryptsetup-initramfs/conf-hook
CRYPTSETUP=y
you’ll see it in the conf-hook file commented out, just set it as above and it will work again.
If you build a system with encryption, I believe this gets changed at some point, but the live builds are systems that are not built like this, and there isn’t a lot to go on to direct you to make this change.
When you set that and re-make your iso image, you’ll be able to do encrypted persistence again. Worked for me on latest Kali January 2019. :-)
なるほど，この環境はいつも development branch にしているのでこの問題に当たったようですね．
/etc/cryptsetup-initramfs/conf-hook を CRYPTSETUP=y と編集して，
$ sudo vi /etc/cryptsetup-initramfs/conf-hook $ sudo git diff HEAD /etc/cryptsetup-initramfs/conf-hook diff --git a/cryptsetup-initramfs/conf-hook b/cryptsetup-initramfs/conf-hook index 8a6a474..fdd7920 100644 --- a/cryptsetup-initramfs/conf-hook +++ b/cryptsetup-initramfs/conf-hook @@ -15,7 +15,7 @@ # cryptsetup initramfs integration. # -#CRYPTSETUP= +CRYPTSETUP=y # # KEYFILE_PATTERN: ...
apt でfix-broken を掛けると正常にinitramfs が通り，再起動して新しいkernal で起動しました :)
