The following packages have unmet dependencies:
 php7.2-curl : Depends: php7.2-common (= 7.2.34-23+ubuntu21.04.1+deb.sury.org+1) but 7.2.34-24+0~20210826.64+debian9~1.gbp428dfa is to be installed
E: Unable to correct problems, you have held broken packages.

i find some solution to fix this issue (sudo apt-get install libcurl13 php7.2-curl) when i run this command it shows following error ,How to resolve the issue ,Help me to fix this issue

Package libcurl3 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libcurl4:i386 libcurl4

E: Package 'libcurl3' has no installation candidate

    Does this answer your question? How do I resolve unmet dependencies after adding a PPA?

  • "you have held broken packages" - package management must be in order before installing new software. sudo apt update should be executed before any other apt commands so that you are dealing with the current list of available software and generally updates need to be completed with sudo apt upgrade before installing anything new.

  • @pLumo, that's not related to my question

  • Your sources are clearly broken because you added some non-standard repositories. If it is a ppa or a manually added repo doesn't matter, the duplicate explains it very well how to fix it.

libcurl3 has been replaced by libcurl4 in Ubuntu 21.04, so if you install libcurl4 Ubuntu will use it instead of libcurl3. Open the terminal and type:

sudo apt update
sudo apt install libcurl4
sudo ln -s /usr/lib/x86_64-linux-gnu/libcurl.so.4.5.0 /usr/lib/x86_64-linux-gnu/libcurl.so.4.7.0
sudo apt install php7.2-curl
