Error reading ca cert file

[Peter Carr]

When I try to use git clone as below I get an error

git clone https://github.com/OnionIoT/oledQrCodeGenerator.git

Cloning into 'oledQrCodeGenerator'...
fatal: unable to access 'https://github.com/OnionIoT/oledQrCodeGenerator.git/': Error reading ca cert file /etc/ssl/certs/ca-certificates.crt - mbedTLS: (-0x3E00) PK - Read/write of file failed

ls -ld /etc/ssl/certs

drwxr-xr-x 2 root root 20411 Feb 2 15:46 /etc/ssl/certs

I am root.
ca-certificates.crt is not present

Any idea what I need to do to fix this?

OK.
I found the problem After I searched the tags.

opkg install ca-bundle
