Tried to install LuaSec on a new machine recently and got the following error:
luarocks install luasec
Warning: Failed searching manifest: Failed loading manifest: Failed fetching manifest for http://luarocks.org/repositories/rocks – Error fetching file: Failed downloading http://luarocks.org/repositories/rocks/manifest – URL redirected to unsupported protocol – install luasec to get HTTPS support.
So all I need to do to install LuaSec is install LuaSec first, brilliant!
One solution is buried here https://github.com/luarocks/luarocks-site/issues/6
and is to specify the server directly:
luarocks install –only-server=http://rocks.moonscript.org luasec
To run systemtap you need debuginfo, but it fails when installing linux image with :
apt-get source linux-image-4.4.0-53-generic-dbgsym
Reading package lists… Done
Picking ‘linux’ as source package instead of ‘linux-image-4.4.0-53-generic-dbgsym’
And then fails to find ‘linux’
Solution is to uncomment ‘deb-src’ in /etc/apt/sources.list, run apt-update again, and then
sudo apt-get build-dep –no-install-recommends linux-image-$(uname -r)
Running system tap gives the error: ‘error: ‘struct module’ has no member named ‘symtab’’
This is caused by a bug with system tap not containing symtab for ubuntu 16+ in version 2.9, and can be solved by upgrading to systemtap 3.0+ by compiling from source.
