While i try "apt-get install libcunit1=2.1-3-dfsg-2build1 libcunit1-dev"on Ubuntu Server 23.04，it failed!

All environments are default

The following packages have unmet dependencies:
 libcunit1-dev : Depends: libcunit1 (= 2.1-3-dfsg-2build1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

    The package available for lunar or 23.04 is libcunit1 | 2.1-3-dfsg-2.4 | lunar/universe | amd64, arm64, armhf, i386, ppc64el, riscv64, s390x which is the version required by the package you mention (https://packages.ubuntu.com/lunar/libcunit1-dev) so your problem is likely a 3rd party source of which you gave no specifics. – guiverc Aug 09 '23 at 03:26
  • Did you update before you install? – rocky rocky Aug 09 '23 at 03:27
  • @guiverc, you are right. This is the issue I encountered while trying to build the kernel and installing some prerequisite libraries befor that. I opened the source code of the script, and it doesn't provide any specific version or environment requirements. Here is the script I'm providing, hoping it can give you some insights for problem-solving. #meson apt-get install -y libiniparser1 libiniparser-dev libkmod-dev ibkeyutils-dev apt-get install -y libjson-c3 libjson-c-dev libudev1 libudev-dev ninja-build meson. – HuaLi Aug 09 '23 at 06:26
  • This is a Q&A site and not a forum (https://ubuntuforums.org/ being the address of Ubuntu Forums). If you have details you want people to read, please edit your question and add them there (easier to read etc & greater editing options; we can help you with edits if required too) Providing details of where the script was from is also helpful (the -y I see makes me nervous; as it requires assumptions that were probably documented where the script was from!) You can always start another question, but be specific & clear with what you've done & give all details. – guiverc Aug 09 '23 at 06:35
  • thank you@guiverc,i'll post my question in other forum.I will also learn how to edit my questions to make them more beautiful and easier to read. – HuaLi Aug 09 '23 at 06:43
  • Can you recommend some websites to me? I am not sure where I can go to better consult and solve my problems. – HuaLi Aug 09 '23 at 07:08
  • This site is fine; my point was this is a Q&A site and not a forum (ie. you provide a question here, and it's answered by answers that follow it.. Comments are just comments on the question & not additional detail (those belong in the question itself)... ie. I was attempting to aid in how this and Q&A sites work (alas maybe not in the best way). All details belong in your question being my last point. Answers will not be to comments, but only to question itself; comments are not intended for replies from OP or Original Poster; they're just comments on the question – guiverc Aug 09 '23 at 07:11
