This would also be useful to add to the download page here, given it will effect anyone using Linux Mint (since those repos have a Pin Priority of 700, and sublime-text is in the repo): https://www.sublimetext.com/docs/3/linux_repositories.html
I finally broke down and figured out why my sublime-text version was stuck on 3143, and how to fix it so it doesn’t happen again. I’m running linux mint, but this will apply to anyone using an apt/dpkg/deb based distro, who gets the “There’s an upgrade available for sublime text!” popup in ST3, but checking for upgrades using your package manager shows you’re on the latest version. In my case, this happened to be 3143, but it could be any ST version in some repo other than the Sublime Text official one.
In brief, you simply add the below to your apt preferences, most commonly (in mint, ubuntu and debian) as a new file created in /etc/apt/preferences.d/, which I chose to call sublime-text.pref. This preferences choice is simply going to give higher priority to the official package origin of download.sublimetext.com than other repositories on the system, and is going to do so only for the sublime-text package (just to be safe).
The new file’s contents (/etc/apt/preferences.d/sublime-text.pref) are:
Package: sublime-text
Pin: origin download.sublimetext.com
Pin-Priority: 900
After adding this, just update as normal and you’ll pick up the latest version.
If you’re still having trouble for some reason, try running (with sudo or as root) apt-cache policy sublime-text, after which you should see something like the below:
sublime-text:
Installed: 3143
Candidate: 3143
Version table:
3176 900
900 https://download.sublimetext.com apt/stable/ Packages
*** 3143 950
950 http://example.org/packages version/import amd64 Packages
700 http://mirror.team-cymru.org/mint-packages serena/import amd64 Packages
100 /var/lib/dpkg/status
If you notice, I added an “example.org” package there that has a priority of 950, higher than what we pinned our official priority to be. That’s incredibly uncommon, but if it happens to you just set a priority higher than 950 (in this case) and the official repository will take priority over the example.org one.
