Clone the repo somewhere:
git clone https://github.com/teejee2008/timeshift.git
Change directory:
cd timeshift/src/Utility
Edit the file Devices.vala, find line 431, change MAJ:MIN
to MAJ[_:]MIN
Repeat for the next line (2 line below???).
Should now look like:
try{
if (lsblk_is_ancient){
rex = new Regex("""NAME="(.*)" KNAME="(.*)" LABEL="(.*)" UUID="(.*)" TYPE="(.*)" FSTYPE="(.*)" SIZE="(.*)" MOUNTPOINT="(.*)" MODEL="(.*)" RO="([0-9]+)" RM="([0-9]+)" MAJ[_:]MIN="([0-9:]+)"""");
}
else{
rex = new Regex("""NAME="(.*)" KNAME="(.*)" LABEL="(.*)" UUID="(.*)" TYPE="(.*)" FSTYPE="(.*)" SIZE="(.*)" MOUNTPOINT="(.*)" MODEL="(.*)" RO="([0-9]+)" HOTPLUG="([0-9]+)" MAJ[_:]MIN="([0-9:]+)" PARTLABEL="(.*)" PARTUUID="(.*)" PKNAME="(.*)" VENDOR="(.*)" SERIAL="(.*)" REV="(.*)"""");
}
# cd back to the timeshift clone directory:
make
sudo make install
