Re: [FIXED] journalctl: cannot view old boots

^It looks OK to me:

john@bunsen1:~$ ls -ld /var/log/journal
drwxr-sr-x 7 root systemd-journal 4096 Oct 30 10:26 /var/log/journal

Here;

bra10n@Aspire-5750:~$ ls -ld /var/log/journal
drwxr-sr-x 3 root systemd-journal 4096 Oct 29 19:01 /var/log/journal

So if I'm correct, you have permissions to rwx and cannot read journal logs, while here I have wx only and everything works. Strange.

Re: [FIXED] journalctl: cannot view old boots

I did some checking on this. I was having the same issues @johnraff, which backporting systemd appears to have resolved. Once I backported systemd, setting storage to persistent and ensuring I was part of systemd-journal gave me proper handling of multiple boot logs as shown below:

Re: [FIXED] journalctl: cannot view old boots

@tknomanzr thanks for that.

john@bunsen1:~$ apt-cache policy systemd
systemd:
  Installed: 215-17+deb8u5
  Candidate: 215-17+deb8u5
  Version table:
     230-7~bpo8+2 0
        100 http://ftp.riken.jp/Linux/debian/debian/ jessie-backports/main amd64 Packages
 *** 215-17+deb8u5 0
        500 http://ftp.riken.jp/Linux/debian/debian/ jessie/main amd64 Packages
        100 /var/lib/dpkg/status

So systemd version 230 is available in the backports.

Probably a pile of other unpublicized bugs will have been fixed in there, but now I've got a workaround for my immediate needs I'll stay with 215 for the moment - mainly because it would be another complicating factor when helping trying to help other BL users...

But for any other people with this issue, I'd suggest taking tk's advice and upgrading systemd to 230 from jessie-backports.
