error running rpi-update curl: (6) Couldn't resolve host 'github.com'

[TheQuestor]

When running rpi-update I now get an error that it can't resolve host github.com *\ Downloading specific firmware revision (this will take a few minutes) curl: (6) Couldn't resolve host 'github.com'

gzip: stdin: unexpected end of file tar: Child returned status 1 tar: Error is not recoverable: exiting now

but I am able to ping it just fine

Can you run: curl -L https://github.com/Hexxeh/rpi-firmware/archive/master.tar.gz > /dev/null

and report the output?

[Ruffio]

@TheQuestor is this still an issue? If yes please back with @popcornmix suggestion or close this issue if it is not relevant anymore.

It is working now but oddly not until I did a "sudo apt-get install ca-certificates" but yah I just did a "sudo rpi-update" and it all went through just fine but now my spi is no longer working sigh. and in X the taskbar keeps coming on and going off. The 5" TFT + Touch screen is working ok but it is all messed up. I should not have done this without backing up first :(

here is a video of what it is doing now. https://youtu.be/TviZnNV8oys

going to try a dist-upgrade to see if it fixes it.

[Ruffio]

@TheQuestor As the original issue is solved this should be closed then

[TheQuestor]

Here is what I did

pi@rpi2 /devel $ curl -L https://github.com/Hexxeh/rpi-firmware/archive/master.tar.gz curl: (60) SSL certificate problem: unable to get local issuer certificate More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. pi@rpi2 /devel $ git config --global http.sslVerify true pi@rpi2 /devel $ sudo apt-get install ca-certificates

pi@rpi2 /boot $ sudo reboot

and whilst the original issue seems to be fixed the result is far from good :(

but as requested I will close this and format my SD Card and start over from scratch [not happy sigh]

just for reference here is my dmesg
