问题
I am currently attempting to install RVM on an Ubuntu server using version 8.04.4.
At the moment I am a attempting a single user install. I am the only person who administers this machine and I am still pretty noobish at this. I am currently following he installations guide on the RVM site and added the 'k' flag to the curl command. The complaints about the certificate still do not go away.
$ bash -s stable < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
Downloading RVM from wayneeseguin branch stable
curl: (77) error setting certificate verify locations:
CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: none
Could not download 'https://github.com/wayneeseguin/rvm/tarball/stable'.
curl returned status '77'.
My ultimate goal is merely to upgrade ruby from v1.8.6 to 1.9.2 on this machine.
I've noticed many people recommending against a multi-user installation which is why I have yet to attempt it. Is it recommended that I try a multi-user installation? If not can someone assist me in eradicating this certificate issue?
Thanks in advance.
回答1:
Do it single user. Your problem isn't RVM though -- it's the CA certs.
Read this link and make sure your SSL is up to date, and you have installed the CA certs:
https://help.ubuntu.com/community/OpenSSL
To install ca certs on Ubuntu using apt:
apt-get install ca-certificates

according to man curl this problem is:
77 Problem with reading the SSL CA cert (path? access rights?).
I guess you have sissues with access rights to the mentioned file:
/etc/ssl/certs/ca-certificates.crt
make sure is readable for all users:
sudo chmod 755 /etc/ /etc/ssl/ /etc/ssl/certs/
sudo chmod 644 /etc/ssl/certs/ca-certificates.crt
