Hi,

Thanks for the report 👍

The error is for uninstall of Xserver. During the uninstall menu, which items did you select for uninstall?
eg:

• VNC4
• Xserver

With the above info, we can try to replicate/resolve.

---

Notes:

• We only install libice6 as part of MPD jessie

I also tried uninstalling only VNC4 and got this one:

@aaro668

Thanks 👍

E: Unable to locate package realvnc-vnc-server

This is resolved for v6.2 (release tomorrow). I'll try to replicate the other issue.

[Fourdee]

🈴 Confirmed RPi uninstall of:
VNC 4
LXDE
Xserver
ALSA

Issue is due to uninstall order of Xserver (being 1st), we need to ensure its uninstalled last.

[aaro668]

Ok, so how do I un-install from my system?

[Fourdee]

@aaro668

Please wait.

[Fourdee]

@aaro668

Uninstall workaround:

dietpi-software uninstall 23 28 5 6

[aaro668]

Ok, thanks, should I run cleanup after un-install?

[Fourdee]

@aaro668
No need, DietPi will run apt-get autoremove --purge automatically at the end.

[aaro668]

Using workaround (dietpi-software uninstall 23 28 5 6)
I get this error yet:

@aaro668

Ah yes, this requires v6.2, please update the global script temporarily for this uninstall:

mv /DietPi/dietpi/func/dietpi-globals /DietPi/dietpi/func/dietpi-globals.bak
wget https://raw.githubusercontent.com/Fourdee/DietPi/testing/dietpi/func/dietpi-globals -O /DietPi/dietpi/func/dietpi-globals
chmod +x /DietPi/dietpi/func/dietpi-globals
dietpi-software uninstall 23 28 5 6
mv /DietPi/dietpi/func/dietpi-globals.bak /DietPi/dietpi/func/dietpi-globals

[Fourdee]

Moved to 6.3:

• We require an ordering system for Uninstalls
• Installs have this currently via location in script
• Maybe an additional array for "install order index" assigned to each software title, we can use to order install/uninstall.

[aaro668]

Got it un-installed with this:
mv /DietPi/dietpi/func/dietpi-globals /DietPi/dietpi/func/dietpi-globals.bak
wget https://raw.githubusercontent.com/Fourdee/DietPi/testing/dietpi/func/dietpi-globals -O /DietPi/dietpi/func/dietpi-globals
chmod +x /DietPi/dietpi/func/dietpi-globals
dietpi-software uninstall 23 28 5 6
mv /DietPi/dietpi/func/dietpi-globals.bak /DietPi/dietpi/func/dietpi-globals

thanks!

Since doing the uninstall the blynkserver service isnt running successfully, any pointers why this is happening?

@aaro668

Could be a pre-req from the uninstalled items.

What happens when you run?:

/usr/bin/java -jar /etc/blynkserver/server.jar -serverConfig /mnt/dietpi_userdata/blynk/server.properties

[aaro668]

root@DietPi-Clare:~# service blynkserver stop
root@DietPi-Clare:~# /usr/bin/java -jar /etc/blynkserver/server.jar -serverConfig /mnt/dietpi_userdata/blynk/server.properties
-bash: /usr/bin/java: No such file or directory
root@DietPi-Clare:~#

[Fourdee]

@aaro668

One of the uninstalled software items most likely removed Java, due to APT req's (out of our control).

Easiest solution, reinstall blynkserver (which automatically pulls in java):

dietpi-software reinstall 131

[aaro668]

ok, but I have apps and settings already for Blynkserver, will those be overwritten? I would prefer not to have to set everything up again.....

[Fourdee]

@aaro668

The only thing I can see that will be overwritten during reinstall is "$G_FP_DIETPI_USERDATA"/blynk/server.properties file, however, to avoid any potential loss, please create a full system backup before hand:

dietpi-backup

[aaro668]

Thanks, it worked

[MichaIng]

I will close in favour of: https://github.com/Fourdee/DietPi/issues/1462
Collect ideas there how to realize specific uninstall order.
