While I entirely support the idea of snapd no longer caring about gccgo, this report does indicate a clear bug so I've uploaded a fix for dh- golang to the SRU queue.
** Description changed: - We see this kind of error in recent runs of snapd tests when using - bionic updating gccgo 4:8.2.0-1ubuntu2.1 and current dh-golang 1.34. + [impact] + Packages that use gccgo-go to build fail to build. There aren't really any such packages in Ubuntu today, but it's still a broken situation. + + [test case] + $ apt source golang-petname + $ cd golang-petname-*/ + $ sed -i -e 's/golang-go/gccgo-go/' debian/control + $ apt build-dep ./ + $ dpkg-buildpackage + + [regression potential] + It's just a small patch from Debian, so very slight. It's caused no problems in Debian or cosmic. + + [original description] + We see this kind of error in recent runs of snapd tests when using bionic updating gccgo 4:8.2.0-1ubuntu2.1 and current dh-golang 1.34. Can be run from snapd master checkout with: spread -v -debug google:ubuntu-18.04-64:tests/unit/gccgo with the proper configuration.

Seems related/similar to https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=907263 which mentions dh-golang 1.35 having a fix. ** Changed in: dh-golang (Ubuntu Bionic) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1794936 Title: new gccgo version update (4:8.2.0-1ubuntu2.1) is triggering dh-golang <1.35 bug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dh-golang/+bug/1794936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
