01 Apr '19

Hello! Can you please update the image used by test kvm-deb-jessie-ppc64le so that the 'apt-get update' is fresh and package lists are recent? It would fix the error in http://buildbot.askmonty.org/buildbot/builders/kvm-deb-jessie-ppc64le/build… E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/m/mpfr4/libmpfr4_3.1.2-2_ppc64el.… 404 Not Found [IP: 64.50.233.100 80] E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/g/gcc-4.9/libatomic1_4.9.2-10_ppc… 404 Not Found [IP: 64.50.233.100 80] E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/r/rsync/rsync_3.1.1-3_ppc64el.deb 404 Not Found [IP: 64.50.233.100 80] E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/s/socat/socat_1.7.2.4-2_ppc64el.d… 404 Not Found [IP: 64.50.233.100 80] E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/libd/libdbd-mysql-perl/libdbd-mys… 404 Not Found [IP: 64.50.233.100 80] Also, can you please run 'apt-get install libzstd-dev' in the image used in arm64-xenial-deb? It would fix http://buildbot.askmonty.org/buildbot/builders/arm64-xenial-deb/builds/2973… dpkg-checkbuilddeps: error: Unmet build dependencies: libzstd-dev dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting Thanks!

I found a reply in the mailing list archive which haven't reached my inbox: From: Reindl Harald Date: Thu, 28 Mar 2019 11:59:50 +0100 > just run "mysql_upgrade" after each update and you are done > our production datadirs date back to 2002, originally on windows then > moved to MacOS and in 2008 to Fedora and i did not dump/restore a single > time in my whole life, this is not postgresql My question is focused on the clarification in our downstream documentation. So while usually I'd be fine with personal experience, in this case, I'd prefer more in-depth answer covering. I'm forwarding this mail to devel mailing list. -- Michal Schorm Software Engineer Core Services - Databases Team Red Hat --
