Bug #15684

Updated by Peter Amstutz almost 3 years ago

https://ci.curoverse.com/view/Build-it/job/build-packages-centos7/1796/console 

 Findings so far. 

 I think what is happening is something like this: 

 # build arvados-server v1 
 # build arvados-api-server v1 
 # build arvados-server v2 
 # try to install arvados-api-server v1 
 ## depends on arvados-server v1 
 ## fail because only arvados-server v2 package is available (also a package version conflict since we are pinned to arvados-server v1 but more recently built package would be pinned to arvados-server v2) 

 Proposed solution: assign version as latest(api-server, arvados-server). 

 Second finding:  
 -Installing  

 Installing arvados-api-server doesn't appear to pull in arvados-server as a dependency.    Which suggests the dependency is missing on all the deb based builds.-  

 Debian packages do have a dependency on arvados-server, but for some reason apt-get doesn't log anything about installing it. 

 The actual reason that builds.    Which would explain why only centos7 is failing: 

 There is a feature to download already-built dev packages, to avoid building them again.   

 In the centos7 build, this means it fetches the already existing package, which may have been built depending on an older arvados-server package.    This causes the package install test to fail when the arvados-server package is newer than the arvados-api-server package. 

 However, the "download existing packages" code is presently broken for deb packages (uses the wrong URL).    As a result, deb packages are always rebuilt.    This means arvados-api-server gets rebuilt at the same version number, but with a dependency on the latest arvados-server package.    Testing succeeds, but now we're in a situation where we are be rebuilding a package with the same version number but different metadata. failing.
