I got this strange (to me, anyway :)) build[1] error recently: 2. Task: 13490-fedora/26, importing the package: https://copr.devel.redhat.com/tmp/tmpvGUgx7/shellfu-0.9.6-1.fc25.src.rpm downloading package https://copr.devel.redhat.com/tmp/tmpvGUgx7/shellfu-0.9.6-1.fc25.src.rpm Verifying packagage, getting name and version. make sure repos exist: amahdal/rhtools/shellfu cmd: ['/usr/share/dist-git/setup_git_package', 'amahdal/rhtools/shellfu'], rc: 128, msg: ERROR: Package module amahdal/rhtools/shellfu already exists! Package already exists...continuing cmd: ['/usr/share/dist-git/mkbranch', u'fedora/26', 'amahdal/rhtools/shellfu'], rc: 128, msg: IGNORING: Package module amahdal/rhtools/shellfu already has a branch fedora/26 Branch already exists...continuing [...] It happened only in one of 7 chroots, while nothing in the project seems relevant to arch or distro (it's noarch, bash-related). Re-build succeeded. [1]: https://copr.devel.redhat.com/coprs/amahdal/rhtools/build/13490/ So probably an one-off thing (rare race condition) but I figured I'd rather report it anyway.
Ouch, sorry I totally missed this, but thanks a lot for the report. That code has been reworked a lot [1] and the error unlikely to repeat. [1] https://pagure.io/copr/copr/pull-request/70
