编译内核的时候,遇到如下告警
gpg: WARNING: some OpenPGP programs can't handle a DSA key with this digest size
###
### Now generating a PGP key pair to be used for signing modules.
###
### If this takes a long time, you might wish to run rngd in the background to
### keep the supply of entropy topped up. It needs to be run as root, and
### should use a hardware random number generator if one is available, eg:
###
### rngd -r /dev/hwrandom
###
### If one isn't available, the pseudo-random number generator can be used:
###
### rngd -r /dev/urandom
###
编译会卡住
解决方法:新起xshell执行如下命令,可能需要安装rngd
rngd -r /dev/urandom
