#293 Ubuntu 17.04 crash at start

[Garyx]

Hi David,

Thank you for PAC, it's been my go to worktool for years. I just tested installing it on the most current setup of Ubuntu 17.04 and I cannot get it to run. Here's a sample of what happens.

Btw I tested it in VM on both Ubuntu Gnome and classic with Unity. Same deal.

perl -d /usr/bin/pac

Loading DB routines from perl5db.pl version 1.49_05
Editor support available.

Enter h or 'h h' for help, or 'man perldebug' for more help.

Found some older bug that suggested to Vte.so from the local pac folder. This seems to work, PAC starts now. Will this have an effect later on?

This will remove the file from the local installation.

# find /opt/pac/ -name "Vte.so*" -exec rm {} +

[mauro cendon]

thank you, you solved my day

[Garyx]

Well no ssh connections work after removing Vte.so* files so that's not an option.

Reinstating the files and having a better look now gave me the follwing errors.

Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine", at /usr/lib/x86_64-linux-gnu/perl5/5.24/Gtk2.pm line 126. Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine", at /usr/lib/x86_64-linux-gnu/perl5/5.24/Gtk2.pm line 126. Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine", at /usr/lib/x86_64-linux-gnu/perl5/5.24/Gtk2.pm line 126. PAC started (pac) with PID 4002 INFO: Used config file '/home/user/.config/pac/pac.nfreeze' Segmentation fault (core dumped)

The Murrine error was fixed by installing gtk2-engines-murrine package.

That left the Segmentation fault. Running perl -d /usr/bin/pac returned the following.

`Loading DB routines from perl5db.pl version 1.49_05

Hope this helps others.

I was able to fix this by applying commands of this post with some changes:

1. apt install libglib2.0-dev libpango1.0-dev libvte-dev libvte-2.91-dev dh-make-perl
2. dh-make-perl --cpan Gnome2::Vte --build
3. sudo dpkg -i libgnome2-vte*.deb
4. sudo find /opt/pac/ -name "Vte.so*" -exec rm {} +

PAC is starting great and SSH connctions are working.

[Ken Haase]

This worked great, but I needed to also install libextutils-pkgconfig-perl and libextutils-depends-perl, i.e change (1) to
1. apt install libglib2.0-dev libpango1.0-dev libvte-dev libvte-2.91-dev dh-make-perl libextutils-pkgconfig-perl libextutils-depends-perl,

Is there a way to get this answer to float to the top? It would be helpful to whoever runs into this problem next.

Thanks!

I'm running Ubuntu 17.04 but Step 3 didn't work for me, so I tried: sudo apt-get install libgnome* . Now it works! Thanks

[Thom Michelbrink]

I was getting these errors:
MakeMaker FATAL: prerequisites not found.
ExtUtils::Depends not installed
ExtUtils::PkgConfig not installed

So I had to do..
$ perl -MCPAN -e 'shell'
$ install ExtUtils::Depends
$ install ExtUtils::PkgConfig

Once I got those installed I was able to proceed with step 2 and everything worked perfectly.
Thanks for the fix Matthias!

Hi,
Is there an update scheduled to solve this issue? I really prefer to avoid manual configuration to avoid issue for ... following updates.

im on ubuntu 17.04 with the pac issue, i followed Matthias steps and had the problems that Thom mentions... finally i get PAC gui running and SSH connections too.. thanks

[drsash]

I'm on Ubuntu-Budgie an fixed it with:

I could fix it by forcing PAC to use my system library instead of the embedded one, by removing all Vte.so* from PAC:

find /opt/pac/ -name "Vte.so*" -exec rm {} +

The only error message shows up at start with:

WARNING: Tray icon may not be available:
If on Unity, try installing 'libgtk2-appindicator-perl' package.
If on Gnome3 gnome-shell, you may need to install some extension like 'Evil Status Icon Forever' in order to be able to see PAC's tray icon.
This message will not appear anymore.
See tooltip of 'Preferences' -> 'PAC Main Options' -> 'Behaviour' -> 'At PAC Exit' -> 'Hide to tray instead of closing'
You may reenable Tray icon options under 'Preferences'.

I guess this is because of PAC not knowing Budgie.....but the tray icon seems to work.

Matthias solution worked for me

Genio Matthias!

[Eli Orzitzer]

I had the same issue and used the tricks above.
The program started but no any terminal window.
After some digging I found that when opening it from terminal it works but when opening it from the UI (Ubuntu 17.04, Unity) it doesn't work and the Vte stuff (shared objects - so) isn't loaded at all.

I don't know what is the difference between loading it from the terminal or using the UI.

The solution was: istead of deleting the Vte.so file I replaced the Vte.so link to poing to the new one compiled by me:

ln -s /home/eli/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/auto/Gnome2/Vte/Vte.so /opt/pac/lib/ex/vte64/auto/Gnome2/Vte/Vte.so

Hope it will help someone.

gave up on this but then i found Asbru (fork of PAC that is still maintained) and this solved my problems. I was able to import my PAC connections without any issues :-)
