Installing CKAN on Ubuntu - HebaruSan/CKAN GitHub Wiki
Install dependencies
Set up Mono package repositories
Mono 5 is required, but the Ubuntu repositories only offer Mono 4, so you will need to add the official Mono repositories. Click the following link and follow the instructions in step 1 for your Ubuntu version (17.04 users follow 16.04 instructions, 18.10 users follow 18.04 instructions, etc.):
Install Mono and libcurl
sudo apt install libcurl4-openssl-dev mono-complete ca-certificates-mono
Or if you prefer not to install mono-complete:
sudo apt install libcurl4-openssl-dev ca-certificates-mono libmono-accessibility4.0-cil libmono-addins-gui0.2-cil libmono-addins0.2-cil libmono-cairo4.0-cil libmono-corlib4.5-cil libmono-data-tds4.0-cil libmono-i18n-west4.0-cil libmono-i18n4.0-cil libmono-ldap4.0-cil libmono-microsoft-csharp4.0-cil libmono-posix4.0-cil libmono-security4.0-cil libmono-sharpzip4.84-cil libmono-sqlite4.0-cil libmono-system-componentmodel-dataannotations4.0-cil libmono-system-configuration4.0-cil libmono-system-core4.0-cil libmono-system-data4.0-cil libmono-system-design4.0-cil libmono-system-drawing4.0-cil libmono-system-enterpriseservices4.0-cil libmono-system-ldap4.0-cil libmono-system-net-http-webrequest4.0-cil libmono-system-net-http4.0-cil libmono-system-numerics4.0-cil libmono-system-runtime-serialization-formatters-soap4.0-cil libmono-system-runtime-serialization4.0-cil libmono-system-security4.0-cil libmono-system-servicemodel-internals0.0-cil libmono-system-transactions4.0-cil libmono-system-web-applicationservices4.0-cil libmono-system-web-services4.0-cil libmono-system-web4.0-cil libmono-system-windows-forms4.0-cil libmono-system-xml-linq4.0-cil libmono-system-xml4.0-cil libmono-system4.0-cil libmono-webbrowser4.0-cil libmono-zeroconf1.0-cil mono-4.0-gac mono-gac mono-runtime mono-runtime-common mono-runtime-sgen
Import certificates
See SSL certificate errors if you encounter errors related to certificates or authentication or decryption.
Install CKAN
Download the .deb from the latest release of CKAN and double click it to install. This should add a CKAN icon to your system menus.
Or download the .exe and in console run:
mono ckan.exe
If that doesn't work, try:
/usr/local/bin/mono ckan.exe
On some systems CKAN might present an error/warning about not being able to set x locale modifiers. This can be fixed by running:
LC_ALL=en_US.UTF-8 /usr/local/bin/mono ckan.exe
