reinstall of freecad-daily

[keithsloan52]

Think my copy of freecad-daily got corrupted so did
sudo apt-get remove freecad-daily and sudo ap-get purge freecad-daily then installed again
sudo apt-get install freecad-daily but on startup I get

Code: Select all

FreeCAD 0.19, Libs: 0.19R

Traceback (most recent call last):
  File "<string>", line 1, in <module>
<class 'ModuleNotFoundError'>: No module named 'AttachmentEditor'

Also not convinced that the purge works as I get some messages from Modules in /usr/share/freecad-daily/

If at some point you've put files in to that location, you'll have to remove them manually.

Same problem again

I run

Code: Select all

sudo apt-get remove --purge freecad-daily

Followed by

Code: Select all

sudo apt-get install freecad-daily

And freecad-daily no longer works and things like /usr/lib/freecad-daily are not setup.

And freecad-daily no longer works and things like /usr/lib/freecad-daily are not setup.

As kremitzki says, if there are files left over in some directories, you may have to remove them manually with

Code: Select all

sudo rm -rf /usr/share/freecad-daily
sudo rm -rf /usr/lib/freecad-daily
etc.

Also notice that you may have to purge other packages as well

Code: Select all

libfreecad-daily-python2-0.19
libfreecad-daily-python2-0.19:i386
libfreecad-daily-python3-0.19
libfreecad-daily-python3-0.19:i386
libfreecad-python2-0.18
libfreecad-python2-0.18:i386
libfreecad-python3-0.18
libfreecad-python3-0.18:i386

Code: Select all

sudo rm -rf /usr/lib/freecad-daily-python3
sudo rm -rf /usr/lib/freecad-daily-python2
etc.

[keithsloan52]

Tried

Code: Select all

sudo apt-get remove --purge freecad-daily
sudo rm -rf /usr/share/freecad-daily
sudo rm -rf /usr/lib/freecad-daily
sudo apt-get install --reinstall freecad-daily

Does not work. Don't see why the rm's are needed anyway. Purge should get rid of everything.
Sure this does not happen on other software.
Seems to me FreeCAD info for apt-get especially remove and purge is not complete.

[kkremitzki]

Purge merely removes configuration files in addition to doing what remove does, it doesn't completely wipe paths.

When you do this, do you see anything unusual in your apt install output? Under the hood, these postinst scripts get run on installation to manage the symlinks needed for FreeCAD to work:
https://salsa.debian.org/science-team/f ... 3.postinst
https://salsa.debian.org/science-team/f ... 2.postinst

Code: Select all

#!/bin/sh

set -e

update-alternatives --install /usr/bin/freecad-daily freecad-daily /usr/lib/freecad-daily/bin/freecad-python3 30 \
                    --slave /usr/bin/freecadcmd-daily freecadcmd-daily /usr/lib/freecad-daily/bin/freecadcmd-python3 \
                    --slave /usr/lib/freecad-daily/lib freecadlib-daily /usr/lib/freecad-daily-python3/lib

#DEBHELPER#

exit 0

So it tries to create a symlink at /usr/bin/freecad-daily, /usr/bin/freecadcmd-daily, and /usr/lib/freecad-daily/lib. After removal, those files should not exist, and if they do, the postinst script will fail, resulting in a broken installation.

As far as I can tell this problem keeps popping up because people are sometimes given the advice to install things in system paths like /usr/lib/freecad-daily/Mod, and then when the system tries to do something to what should be a system-managed location, it fails because it detects the user has modified it and isn't sure how to proceed safely. If this is happening from other workflow, there's a bug, but nobody has indicated such a workflow for me to investigate.

Okay when I listed /usr/bin/free* the daily versions were still there. Listed in red which I remember correctly means broken in some form.
Did

Code: Select all

sudo rm /usr/bin/freecad-daily
sudo rm /usr/bin/freecadcmd-daily

Nothing in /usr/lib/freecad-daily*

Tried install with

Code: Select all

sudo apt-get install --reinstall freecad-daily

It did not create anything in /usr/bin/free* so cannot start by just typing freecad-daily

In /usr/lib it created

Code: Select all

/usr/lib/freecad-daily-python3:
lib

[kkremitzki]

Tried install with

Code: Select all

sudo apt-get install --reinstall freecad-daily

Try the same command with freecad-daily-python3 package, freecad-daily is just a meta-package that pulls in other freecad packages that have the actual content.

[keithsloan52]

Tried and got

Code: Select all

Setting up freecad-daily-python3 (0.19~pre2~202001131534~ubuntu18.04.1) ...
update-alternatives: warning: forcing reinstallation of alternative /usr/lib/freecad-daily/bin/freecad-python3 because link group freecad-daily is broken

Could start freecad-daily but clearly broken so tried

Code: Select all

sudo apt-get remove --purge freecad-daily-python3
sudo apt-get install --reinstall freecad-daily-python3 

Got error

Code: Select all

/usr/bin/freecad-daily (freecad-daily) in auto mode
update-alternatives: warning: skip creation of /usr/lib/freecad-daily/lib because associated file /usr/lib/freecad-daily-python3/lib (of link group freecad-daily) doesn't exist

Do an 'autoremove' then 'update' before you reinstall.
