libkdevplatform53-libs depends on unavailable libkasten3okteta1controllers1abi1. I guess the okteta version increased. This might be fixed in Dev unstable already. STEPS TO REPRODUCE 1. Use KDE Neon Developer Stable 2. sudo apt install kdevelop OBSERVED RESULT > The following packages have unmet dependencies: > kdevelop : Depends: kdevplatform53-libs but it is not going to be installed > E: Unable to correct problems, you have held broken packages. A bit more precise: > #sudo apt install kdevplatform53-libs > The following packages have unmet dependencies: > kdevplatform53-libs : Depends: libkasten3okteta1controllers1abi1 but it is not installable SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.15.2 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.0
THanks for the notice, it needed a recompile after the okteta library changes, now done and it now installs and runs.
Please reopen if it has not been fixed in the meantime.
