when you try to install any software after lazarus
you get errors like this:
Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution)
and
fp-units-fcl : Depends: fp-units-fcl-3.0.0 (= 3.0.0+dfsg-2) but it is not going to be installed
thi
that was ubuntu 16 ,(in virtual box)
in ubuntu 17 i have no problem.
Please provide more information. Did you install it using Ubuntu Software Center or deb files provided by Lazarus team?
You should not use Ubuntu Software Center, it is a very bad tool. Alternatively you can try Synaptic Package Manager. Here is how I install Lazarus on Ubuntu Mate:
1. Remove all of them (Lazarus, FPC, FPC sources)
2. Retart you computer. Yes, do it. It ever caused me headache.
3. Download the 3 deb files.
4. Install fpc_3.0.2-170225_amd64.deb
5. Install fpc-src_3.0.2-170225_amd64.deb
6. Install lazarus-project_1.6.4-0_amd64.deb
7. Use Synaptic Package Manager to lock version of the installed things
Notes:
- The file names in step #4, #5, #6 may be different.
- If you get version conflict warning, ignore it and nothing bad will happen
- Ubuntu will ask you to use their version, don't use theirs.
- Your installation will be replace with Ubuntu's version when updating software, so you need to do step #7
