Temporarily access NixOS with encrypted LUKS from Ubuntu Live


  • Boot Ubuntu Live as usual
  • Change keyboard layout with setxkbmap <lang>
  • Install useful packages with sudo apt install vim nix-bin

Open crypt device

  • Idenitify LUKS device with lsblk --fs. Look for crypto_LUKS:
    ├─nvme0n1p1   vfat        FAT32
    └─nvme0n1p2   crypto_LUKS 2
  • Open encrypted device with cryptsetup luksOpen /dev/<root partition (sda2 or similar)> secure
  • Check sucessfull open with lslbk. You should now see the crypt partition(s):
    nvme0n1       259:0    0 476.9G  0 disk
    ├─nvme0n1p1   259:1    0   549M  0 part
    └─nvme0n1p2   259:2    0 476.4G  0 part
    └─enc-pv    253:0    0 476.4G  0 crypt
      ├─vg-swap 253:1    0    16G  0 lvm
      └─vg-root 253:2    0 460.4G  0 lvm

Mount partitions

  • lvchange -a y /dev/vg/swap
  • lvchange -a y /dev/vg/root
  • mount /dev/vg/root /mnt
  • mount /dev/<boot partition (sda1 or similar)> /mnt/boot
  • swapon /dev/vg/swap

    • Update channels nix-channel --update

Microsoft Outlook – Cannot delete this folder

After restoring an Exchange mailbox and sorting the mails, I wanted to delete the restore folder, but Outlook won't let me:

Cannot delete this folder. Right-click the folder, and then click Properties to check your petmissions for the folder, See the folder owner or your administrator to change your permissions, Shared folders cannot be deleted during synchronization with the server. Delete the folder after synchronization is finished

Solution: Move the folder to trash and then delete the folder.

Could not find any disk on this device. PRTG error code: PE188

I got this error when I tried to add a SNMP HP ProLiant Physical Disk Sensor for HP Proliant DL 380 G7 with Windows 2012 R2 in our monitoring solution from Paessler (PRTG). The SNMP HP ProLiant System Health, Network and Storage Controller Sensor works fine.

HPE Insight Management Agents and HPE Insight Management WBEM Providers for Windows are installed.

An SNMP walk against OID (used by Paessler for this sensor) works without errors but also without result.

I found some guys with the same probleme and a solution: The problem was the disk (controller) driver. Installed was v8.0.4.0, which seems to be a standard Microsoft driver. With the original HPE controller driver (for us it works.
