Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202603/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:fonts-jetbrains-mono, so that this is still
visible in the BTS web page for this package.

Thanks.

#1131648#8

Hi,

this currently fails because of kotlin. In debian-java@l.d.o I was told by
Emmanuel Bourg [1] that using kotlin here "remains a risk" because:

So while we could also wait for kotlin in Debian to get fixed, I offer an
alternative solution to this bug: rewrite scripts/GenerateNLVersion.kt in
something that is not kotlin. At the end of this mail, please find a Python
script which does the same as the kotlin script in a third of the lines of
code. It also means you can drop the Build-Depends on kotlin.

What do you think?

Thanks!

cheers, josch

Hi,

this issue is blocking my package reform-tools to transition to testing. I have
sent a patch fixing this issue to this bug nine days ago and CC-ed the uploader
as well as the maintainer without any reaction since then.

I am thus following the developer-reference recommendation to perform an NMU
fixing this issue with zero-delay.

Please find the diff of my NMU attached at the bottom of this mail.

Thanks!

cheers, josch
