Bug#1006603: evolution: Can't lock mbox file: The reported error was “Could not lock “/var/mail/adrian””

[Adrian Immanuel Kiess]

Package: evolution
Version: 3.43.2-2
Severity: normal

Dear Maintainer,

   * What led up to the situation?
     Upgrading Evolution some months ago
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     apt -u dist-upgrade
   * What was the outcome of this action?
     Evolution is unable to lock the mbox file in /var/mail/adrian and reports
error
   * What outcome did you expect instead?
     Evolution being able to read and lock mbox mail file in /var/mail

in the recent Evolution mail reader on Debian/testing, I can't read my local
mails stored in /var/mail/adrian.

The error Evolution spits out is this:

Failed to refresh folder “adrian at lan.dac : INBOX”.

The reported error was “Could not lock “/var/mail/adrian””.

Here is the directory listing of /var/mail on my system:

root at g6 /var/mail # ls -lah
total 1,4M
drwxrwsr-x  2 root     mail 4,0K 28 févr. 07:43 ./
drwxr-xr-x 17 root     root 4,0K 18 oct.  11:49 ../
-rw-rw----  1 adrian   mail    0 28 févr. 07:44 adrian

Reading the mail with Sylpheed works fine.

I searched the Internet with Google, but could not find a solution.

I would be very gladful for help or fix.

Sincerely,

Adrian Kiess
