Package: apparmor Version: 2.11.1-4 Severity: normal Dear Maintainer,
if Chromium is configured as the default web browser, then clicking a hyperlink in Thunderbird has no effect. The following error message is printed: Failed to execute child process “/usr/bin/chromium” (Permission denied). After having a look at /etc/apparmor.d/abstractions/ubuntu-browsers, I noticed that the only lines referring to chromium are the following: /usr/bin/chromium-browser Cx -> sanitized_helper, /usr/lib/chromium-browser/chromium-browser Cx -> sanitized_helper, These paths appear to be incorrect. On Debian testing at least, they should read as follows: /usr/bin/chromium Cx -> sanitized_helper, /usr/lib/chromium/chromium Cx -> sanitized_helper, However, while this does allow Thunderbird to execute /usr/bin/chromium, it still doesn't fix the problem. Clicking on a hyperlink now prints the following stack trace to the console: /usr/lib/chromium/chrome-sandbox: error while loading shared libraries: libpthread.so.0: failed to map segment from shared object [5139:5139:1210/142450.049037:FATAL:zygote_host_impl_linux.cc(196)] Check failed: ReceiveFixedMessage(fds[0], kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid). #0 0x560540008f56 <unknown> #1 0x560540022662 <unknown> #2 0x56053f336803 <unknown> #3 0x56053f335857 <unknown> #4 0x56053f335c37 <unknown> #5 0x56053f05a0af <unknown> #6 0x56053f05e210 <unknown> #7 0x56053f05905f <unknown> #8 0x56053fda3e0b <unknown> #9 0x56053fdab210 <unknown> #10 0x56053fda3514 <unknown> #11 0x56053ebef12c ChromeMain #12 0x7f6bc79ff561 __libc_start_main #13 0x56053ebeefba _start Received signal 6 #0 0x560540008f56 <unknown> #1 0x56053ebd5a58 <unknown> #2 0x5605400092dc <unknown> #3 0x7f6bd314f3b0 <unknown> #4 0x7f6bc7a12a70 gsignal #5 0x7f6bc7a1419a abort #6 0x560540008bc5 <unknown> #7 0x560540022835 <unknown> #8 0x56053f336803 <unknown> #9 0x56053f335857 <unknown> #10 0x56053f335c37 <unknown> #11 0x56053f05a0af <unknown> #12 0x56053f05e210 <unknown> #13 0x56053f05905f <unknown> #14 0x56053fda3e0b <unknown> #15 0x56053fdab210 <unknown> #16 0x56053fda3514 <unknown> #17 0x56053ebef12c ChromeMain #18 0x7f6bc79ff561 __libc_start_main #19 0x56053ebeefba _start r8: 0000000000000000 r9: 00007fff04e189a0 r10: 0000000000000008 r11: 0000000000000246 r12: 00007fff04e18e60 r13: 00000000000000aa r14: 00007fff04e18e50 r15: 00007fff04e18e70 di: 0000000000000002 si: 00007fff04e189a0 bp: 00007fff04e18e40 bx: 0000000000000006 dx: 0000000000000000 ax: 0000000000000000 cx: 00007f6bc7a12a70 sp: 00007fff04e189a0 ip: 00007f6bc7a12a70 efl: 0000000000000246 cgf: 002b000000000033 erf: 0000000000000000 trp: 0000000000000000 msk: 0000000000000000 cr2: 0000000000000000 [end of stack trace] Calling _exit(1).
