Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1606277 Title: log-observe interface is broken in latest snap-confine Status in Snappy Launcher: Fix Released Status in snap-confine package in Ubuntu: New Status in snap-confine source package in Xenial: New Bug description: The log-observe interface is broken due to how we handle bind mounts now. This can be seen with 'snappy-debug': $ sudo snap install snappy-debug $ sudo snap connect snappy-debug:log-observe ubuntu-core:log-observe $ sudo /snap/bin/snappy-debug.security scanlog kernel.printk_ratelimit = 0 Traceback (most recent call last): File "/snap/snappy-debug/22/bin/snappy-security-scanlog", line 580, in <module> sys.exit(main()) File "/snap/snappy-debug/22/bin/snappy-security-scanlog", line 569, in main from_end=opt.only_new) File "/snap/snappy-debug/22/bin/snappy-security-scanlog", line 92, in __init__ self.scan_log(log_file, snap_name, follow, from_end) File "/snap/snappy-debug/22/bin/snappy-security-scanlog", line 157, in scan_log log = open_file_read(log_file) File "/snap/snappy-debug/22/bin/snappy-security-scanlog", line 71, in open_file_read orig = codecs.open(path, 'r', "UTF-8", errors="replace") File "/usr/lib/python3.5/codecs.py", line 895, in open file = builtins.open(filename, mode, buffering) FileNotFoundError: [Errno 2] No such file or directory: '/var/log/syslog' This is because /var/log/syslog is not available at runtime due to the bind mounts. This can be shown by installing hello-world, adjusting /var/lib/snapd/apparmor/profiles/snap.hello-world.sh to have "/**/ r," (to be able to read any directory), reloading the profile, then doing: $ hello-world.sh ... bash-4.3$ ls /var/log/ alternatives.log btmp dpkg.log fsck watchdog bootstrap.log dmesg faillog lastlog wtmp This may also be a problem with other interfaces, I haven't checked extensively, though it seems that /var/lib/extrausers (from the nameservice abstraction) won't work right, and (at least) ppp (/var/log/ppp) and timezone-control (/usr/share/zoneinfo) are also affected. WORKAROUND for snappy-debug: launch outside of the launcher: $ sudo SNAP=/snap/snappy-debug/current PATH=$PATH:/snap/snappy-debug/current/bin /snap/snappy-debug/current/bin/snappy-security scanlog To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1606277/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
