据我所知，我需要安装这两个包才能与 tpm 模块通信。
我在安装这两个包的时候遇到了以下错误：
sudo apt-get install tpm-tools trousers

我该如何解决？
答案1
这意味着您没有安装 TPM 1.2 cip[，但您有 TPM 2.0 芯片。
您无法安装裤子，因为它需要 TPM 1.2 才能工作。
使用以下方法检查 TPM 版本：
user@ubuntu:~$ sudo dmesg | grep -i tpm
[ 0.001234] ACPI: TPM2 0x00000000A1234567 000012 (v03 ABCDEF A B C 00000001 ABC 00000000)
[ 0.123456] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0x1A, rev-id 16)
您必须安装tpm2-tools
