I have been trying to upgrade to lazarus 1.6.2 on *Linux Mint Sarah* with no success. After days of failure, I decided to revert to 1.6.0 using the .deb files from SourceForge. Then using Synaptic for 1.6.0. Lastly using apt-get from the command line. In all cases, the installation of *fpc *fails.
It used to work till I started this upgrade.

All attempts to get fpc working fail, essentially the same way:

┌[ 2001 2.3.0 19:30:33 ~ ]
└> fpc
The program 'fpc' is currently not installed. You can install it by typing: sudo apt install fp-compiler-3.0.0
┌[ 1994 2.3.0 19:30:35 ~ ]
└> sudo apt install fp-compiler-3.0.0
[sudo] password for donz:

fp-compiler-3.0.0 is already the newest version (3.0.0+dfsg-2). 0 upgraded, 0 newly installed, 0 to remove and 37 not upgraded. ┌[ 1993 2.3.0 19:30:59 ~ ]
└> fpc
The program 'fpc' is currently not installed. You can install it by typing: sudo apt install fp-compiler-3.0.0
┌[ 1993 2.3.0 19:31:08 ~ ]
└>

Repeating the apt install gives the same result.

I tried:

┌[ 1998 2.3.0 19:54:00 ~ ]
└> fp-compiler-3.0.0
fp-compiler-3.0.0: command not found
┌[ 1998 2.3.0 19:54:24 ~ ]

Also:

┌[ 1998 2.3.0 19:54:24 ~ ]
└> sudo apt install fpc
[sudo] password for donz:

Reading state information... Done
fpc is already the newest version (3.0.0+dfsg-2).
fpc set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 37 not upgraded.

When I start lazarus, it complains that it can't find the compiler: /usr/bin/fpc
It recommends that I try /usr/bin/ppcx64

/usr/bin/ppcx64 is a link to a non-existent file.

I tried everything I can think of for the compiler with the same results.

Help, please!

Ondrej,
instead of ScaleCoord(N), ScaleCoordBack(N), not better to have ScaleCoord(N, ABack: boolean = false) ?
Both funcs have 95% same code, better to have one.

Please try this:
- uninstall the lazarus package and all fp- packages.
- update your system
- download the new lazarus-project_1.6.2 package from our sourceforge site and install it.
- If your installer did not automatically install the dependencies, install them now

It seems that the apt metadata got corrupted. fpc was not the only package that would not reinstall properly. I had to reload the entire thing and clear the apt cache. I installed the original fpc and it worked.

I then removed fpc and downloaded lazarus-project_1.6.2. Lazarus worked (even though the installation said that there are 88 packages missing). Where can I find out which packages are needed and how to install them?

Thanks,

Don Z.

Never had such a failure.

:)

Normal.

Where can I find out which packages are needed and how to install them?

For example 'apt-get -f install'.
