Nutanix平台虛擬機(UBUNTU)，利用Veeam備份移轉至VMware平台，安裝套件、系統更新出現錯誤

 mount: /var/lib/grub/esp: special device /dev/disk/by-id/scsi-SNUTANIX_VDISK_NFS_4_0_7672_2d41cbaa_025e_4fac_849c_9e620eff5bff-part1 does not exist.
Errors were encountered while processing:
 grub-efi-amd64-signed
 shim-signed

出現上面的訊息，可以試著刪除config.dat cache檔案：

sudo rm /var/cache/debconf/config.dat

再執行 sudo dpkg --configure -a 試試能否解決問題。

移除 nutanix guest tools:

sudo python3 /usr/local/nutanix/ngt/python/bin/uninstall_ngt.py

UBUNTU系統更新 apt update && apt upgrade 出現錯誤訊息：
E: Method https has died unexpectedly!
E: Sub-process https received signal 4.

編輯 .bashrc 檔案，在第1行增加：export  GNUTLS_CPUID_OVERRIDE=0x1

停用VEEAM備份軟體服務：
sudo systemctl stop veeamtransport.service veeamdeployment.service

sudo systemctl disable veeamtransport.service veeamdeployment.service
