libpcre unmet dependencies

  • 772

I have exhausted all things that I found online trying to fix following on ubuntu 22.04

#apt install libpcre2-dev
  The following packages have unmet dependencies:
     libpcre2-dev : Depends: libpcre2-8-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
                    Depends: libpcre2-16-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
                    Depends: libpcre2-32-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
    E: Unable to correct problems, you have held broken packages.

Apparently problem is due to dist-upgrade issue from 21.10.

What I have tried so far:

apt upgrade
apt install -f libpcre2-dev
apt autoclean
apt --fix-broken install

Also here's the output of

apt-cache policy libpcre2-8-0
libpcre2-8-0:
  Installed: 10.40-1+ubuntu21.10.1+deb.sury.org+1
  Candidate: 10.40-1+ubuntu21.10.1+deb.sury.org+1
  Version table:

  1. Eventually I was able to resolve this issue the following way:

    1. Installed apptitude sudo apt install aptitude
    2. Then aptitude install libpcre2-dev
    3. Do not accept default option to keep existing, choose N
    4. Accept solution to downgrade

    The following actions will resolve these dependencies:

         Downgrade the following packages:                                                                                    
1)     libpcre2-16-0 [10.40-1+ubuntu21.10.1+deb.sury.org+1 (now) -> 10.39-3ubuntu0.1 (jammy-security, jammy-updates)]     
2)     libpcre2-16-0:i386 [10.40-1+ubuntu21.10.1+deb.sury.org+1 (now) -> 10.39-3ubuntu0.1 (jammy-security, jammy-updates)]
3)     libpcre2-32-0 [10.40-1+ubuntu21.10.1+deb.sury.org+1 (now) -> 10.39-3ubuntu0.1 (jammy-security, jammy-updates)]     
4)     libpcre2-8-0 [10.40-1+ubuntu21.10.1+deb.sury.org+1 (now) -> 10.39-3ubuntu0.1 (jammy-security, jammy-updates)]      
5)     libpcre2-8-0:i386 [10.40-1+ubuntu21.10.1+deb.sury.org+1 (now) -> 10.39-3ubuntu0.1 (jammy-security, jammy-updates)]
