Denis Arnaud

I first installed RedHat (version 5, in 1998) with Oracle 8, when that latter was delivered on Linux for the first time... on a small Pentium-based computer with 600MB of disk and 64MB of RAM, hence proving to my hierarchy that Linux was ready for professional use. I started to be involved in the Fedora building process by translating documents and package descriptions, and have become a packager in 2009.

Changes/Python3.9

• AirTSP new source
• PyRMOL fails to install

Hello,

Please note that this comment was generated automatically. If you feel that this output has mistakes, please contact me via email (ignatenkobrain@fedoraproject.org).

Your package (rmol) Fails To Install in Fedora 33:

can't install python3-rmol:

 - nothing provides libboost_python38.so.1.69.0()(64bit) needed by python3-rmol-1.00.4-2.fc32.x86_64
 

If you don't react accordingly to the policy for FTBFS/FTI bugs (https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/), your package may be orphaned in 8+ weeks.

P.S. The data was generated solely from koji buildroot, so it might be newer than the latest compose or the content on mirrors.

P.P.S. If this bug has been reported in the middle of upgrading multiple dependent packages, please consider using side tags: https://docs.fedoraproject.org/en-US/rawhide-gating/multi-builds/

Create Vagrant Images

• Vagrant images are built in Koji with the "CreateImage" method, which calls ImageFactory.
• That is fed by a kickstart (e.g., like https://git.fedorahosted.org/cgit/spin-kickstarts.git/tree/fedora-cloud-base-vagrant.ks), from the spin-kickstarts repository (https://git.fedorahosted.org/cgit/spin-kickstarts.git)
• An image comes out the other side, like this: http://koji.fedoraproject.org/koji/taskinfo?taskID=9832786
• The ImageFactory command looks like:

imagefactory --debug base_image --parameter generate_icicle false tdl-ppc64le.xml --file-parameter install_script f22-rc3-base.ks

Tools

• (third party) Review helper tool
• Fedora active user Python script (see also the corresponding Git repository)
