Build: win64: Package 'mingw-w64-dev' has no installation candidate | Roy Osherove | Sep 27 2015
Roy Osherove on Sep 27 2015: Hi All As part of trying to learn more about the bitcoin builds, I am trying to recreate the travis CI build system using TeamCity. Some of the builds work fine, but the windows builds seem to be having a problem with getting mingw dev: [08:31:21][Step 3/3] E: Package 'mingw-w64-dev' has no installation candidate I'm using the same exports env vars as the travis script, and actually using the travis script inside teamcity , incuding adding the PPA for the mingw packages. The PPA seems to be importing fine during the build: [Step 3/3] gpg: keyring `/tmp/tmp_nolyfrh/secring.gpg' created [08:30:48][Step 3/3] gpg: keyring `/tmp/tmp_nolyfrh/pubring.gpg' created [08:30:48][Step 3/3] gpg: requesting key F9CB8DB0 from hkp server keyserver.ubuntu.com [08:30:48][Step 3/3] gpg: /tmp/tmp_nolyfrh/trustdb.gpg: trustdb created [08:30:48][Step 3/3] gpg: key F9CB8DB0: public key "Launchpad PPA for Ubuntu Wine Team" imported [08:30:48][Step 3/3] gpg: no ultimately trusted keys found [08:30:48][Step 3/3] gpg: Total number processed: 1 [08:30:48][Step 3/3] gpg: imported: 1 (RSA: 1) Any ideas why this seems to be working on travis and not on the teamcity build agent? The agent is running inside docker image based on ubuntu.
