下面这段内容是我从论坛上扒下来的，因为我的问题非常类似但没及时记录下来。

update-initramfs: Generating /boot/initrd.img-5.12.9-amd64-desktop
/usr/sbin/mkinitramfs: 85: /usr/sbin/mkinitramfs: modinfo: Text file busy
cryptsetup: WARNING: The initramfs image may not contain cryptsetup binaries
nor crypto modules. If that's on purpose, you may want to uninstall the
'cryptsetup-initramfs' package in order to disable the cryptsetup initramfs
integration and avoid this warning.

setupcon is missing. Please install the 'console-setup' package.
W: plymouth: The plugin label.so is missing, the selected theme might not work as expected.
W: plymouth: You might want to install the plymouth-themes package to fix this.
I: The initramfs will attempt to resume from /dev/nvme0n1p6
I: (UUID=bdfd51a8-931a-4987-af08-b083ea8606c1)
I: Set the RESUME variable to override this.

问题一：没安console-setup，apt search 找，找到了安上。
问题二：cryptsetup-initramfs，自己用的机器不需要加密这东西，sudo apt remove掉。
问题三：RESUME设置，可能是我调整分区删除swap重建后它没有了，sudo nano /etc/initramfs-tools/conf.d/resume, 然后加一行 RESUME=UUID=e9b1cede-1104-4bec-9d3d-e18460d6cca4，就是swap分区的UUID。

错误不出了，继续用，用不下去时删了重装。一路走来，dos, windows, 数不清重装了多少次，deepin安上就没重装过，挺知足的。
