@hlubach Thank you for reporting. You mentioned the latest Linux mint version and Deb file installation, so I assume 7.13.2 version. Could you provide a bit more information below?

• The Deb file you mentioned, is it downloaded from the official https://tribler.org website, can you confirm? If not where did you get it from?
• Could you run the following command on terminal and share the terminal logs? It will show the logs and will give us more insights where the error originated from.

/usr/share/tribler/triber

Just tried the latest vdebfil from the site ,but with the same json message

[drew2a]

The error occurred here:

tribler/src/tribler/core/upgrade/version_manager.py

Lines 314 to 316 in 5914263

	def load(self, file_path: Path):
	self.logger.info(f'Load: {file_path}')
	self.file_data = json.loads(file_path.read_text().strip())

Based on the logs provided, my guess is that there was a corrupted version_history.json

VersionHistory(315) - Load: /home/han/.Tribler/version_history.json

I suppose that just removing this file should solve the problem, @hlubach

[drew2a]

I was able to reproduce the bug by executing the following command:

~/.Tribler 
➜ echo > version_history.json
