Please help me fix this.

I got into the same problem. My solution was to install the older version 2.5.3, which works fine.

[jcrodriguez-dis]

Thanks for the bug report.

Best regards, Juan Carlos.

[jcrodriguez-dis]

I could not replay the problem with the new V2.7.0 of the VPL-Jail-system. Please, try using this release. If fixed close this issue, if not working full detail your installation to try to reproduce it.

Best regards, Juan Carlos.

I upgrade vpl-jail-system from 2.5.3 (work fine) to 2.7.0 and I got this error:

[jcrodriguez-dis]

The issue is confirmed. CentOS 7 uses GCC 4.8 the regular expressions API of C++ compiles but is not supported, when it runs, throws the exception regex_error. To keep compatibility with CentOS 7 the code will need to return to C regular expressions.

Best regards, Juan Carlos.

[jcrodriguez-dis]

The issue has been resolved in the 2.7.1 release.

Thank you!

Everything works correctly.

Hi, I've tried running on Debian 10. The problem occurs for me. Best regards Adam Pawełczak

[jcrodriguez-dis]

Please, Adam Pawełczak, see https://vpl.dis.ulpgc.es/documentation/vpl-jail-system-2.7.1/troubleshooting.html#reporting-a-bug

[adamtppaw]

It seemed I'd exactly the same problem as described above but in Debian 10. Fortunately, it turned out I'd Nginx running and occupying both ports 80 and 443. So, everything works well on Debian 10. I've checked 2.7.0, 2.7.1 and 2.8.0. Bes regards. Adam
