Thunderbird Aktualisieren

Hello Thunderbird Support Team,

I recently updated Thunderbird on my Ubuntu system. After the update, Thunderbird no longer starts normally.

When I try to launch Thunderbird, a window appears showing the following error:

There is also a caret (^) shown below the beginning of the line, as visible in the attached screenshot.

Before the update, Thunderbird was working normally. The problem started immediately after the update.

System information:

OS: Ubuntu 26.04.1 Thunderbird: 157.0.1-1

Could you please help me identify the cause of this issue and provide a solution?

I would also appreciate any recommended diagnostic commands or logs that I should provide to help troubleshoot the problem.

Thank you.

Best regards, Mohsen Rezaee
