  [ !! Copr timeout => sending INT
WARNING: Machine a97e46b4dd5e489ba0437eef36214d35 still running. Killing...
Copr build error: Build failed]: [This is an information from Copr buildsystem that this build is taking too long and reach the timeout level.]

Issue: Copr killed this build because it reached the timeout level. Builds are not allowed to run forever. The default limit is 5 hours (18000 seconds) but users can increase it up to 30 hours (108000 seconds).
Resolution: When you are submitting a new build you can specify the Timeout. The option is available both in WebUI and CLI (--timeout) and is specified in seconds.
