Comment 1 for bug 1861260

The 10.3 series update for 19.04 is now available.

Please use git-buildpackage to fetch and build from the ubuntu-19.04 branch at https://salsa.debian.org/mariadb-team/mariadb-10.3/tree/ubuntu-19.04

The repository uses pristine-tar, so there is no need to separately download the sources. You can just check the signature/SHA1SUM directly from the git-buildpackage generated tarball.

Test builds and testsuite passed on all platforms at
https://launchpad.net/~mysql-ubuntu/+archive/ubuntu/mariadb-10.3/+builds?build_text=&build_state=all

Debdiffs can be created directly from the repo like in a local clone with 'git diff <tag1>..<tag2> debian/'
