AppImage doesnt start in Ubuntu 22.04

[bfgelectronics]

Describe the bug I was trying to execute the app image in ubuntu.

To Reproduce Steps to reproduce the behavior:

1. Download the latest AppImage from the official flipper website, 1.2.2 was the version in my case
2. runned chmod + x on the AppImage
3. executed the AppImage
4. The App image crashed with the error: Cannot mix incompatible Qt library (5.15.2) with this library (5.15.3) /tmp/.mount_qFlippTNPrEz/AppRun.wrapped: line 87: 27249 Aborted (core dumped) "$THIS_DIR"/usr/bin/qFlipper

Expected behavior The AppImage should execute and open sucesfully.

Actual behavior The app just crashed.

I was not able to reproduce this on an Ubuntu 22.04 VM. Could you please give me the output of apt list --installed | grep qt? This might help finding the package which causes the trouble.

[bfgelectronics]

@gsurkov this is the output of that comand:

base) bfg@bfg-System-Product-Name:~$ apt list --installed | grep qt

Installed all of the above packages, but was unable to reproduce the problem still.

Do you have any special Qt-related environment variables set? (You can find it out by running env | grep QT). A custom Qt style, maybe?

[bfgelectronics]

This is the output on the terminal if i run the command you mentioned:

QT_ACCESSIBILITY=1
QT_IM_MODULE=ibus

Also i did some digging on forums and i found out that this issue might be caused my the Nvidia drivers (the proprietary ones) but I'm not sure.

Edit: also i dont know if it helps , but i get the same error when I try to run ncu-ui

[gsurkov]

It's unlikely that the drivers cause the issue. (Unless they somehow messed with LD_LIBRARY_PATH or LD_PRELOAD).

Could you post the full output of the env command? (environment variables can contain personal data, check it before posting).

[bfgelectronics]

This is the output of the env command, i looked over it and i dont see anything suspicious and also it shouldnt have any sensitive info:

[gsurkov]

I see that LD_LIBRARY_PATH is not empty. Try unsetting it before launching qFlipper AppImage: LD_LIBRARY_PATH= ./qFlipper.... etc

The second possible source of the problem may be the Conda installation (it might include PyQt, which could theoretically somehow override some of the bundled libraries). Try launching qFlipper in a clean shell with no Conda-related stuff loaded.

[bfgelectronics]

It seems that the LD_LIBRARY_PATH is the problem and not the conda env. by running the qFlipper AppImage with this command LD_LIBRARY_PATH= ./qFlipper-x86_64-1.2.2.AppImage , it works (or at least i am on the connect flipper screen)

[gsurkov]

I will think about force-unsetting LD_LIBRARY_PATH in the AppImage environment so that there will be no problems in case it has been set manually.
