Forrest Yelverton gracieously provided this HOWTO on how to get any TSX version beyond 13823 running on my StellarMate OS 2.0+.

Error was missing linked library:
libicui18n.so.72 => not found
libicuuc.so.72 => not found

The required packages to resolve this are Debian based:
http://deb.debian.org/debian/pool/main/i/icu/libicu72_72.1-3%2bdeb12u1_arm64.deb

Please follow these steps:
1. Disable StellarMate OS atomic updates since 3rd party package installation is disabled by default:

sudo /etc/stellarmate/atomic-updates.sh --disable

2. Install "debtap" with:

yay -S debtap

3. Download the DEB package above. File will be libicu72_72.1-3+deb12u1_arm64.deb
4. Move to the directory containing the Deb files just downloaded
5. Run:

debtap libicu72_72.1-3+deb12u1_arm64.deb

6. Run sudo pacman -U libicu72-72.1-1-aarch64.pkg.tar.zst Results in several new folders.
7. Navigate to "DownloadFolder"/usr/lib/aarch64-linux-gnu
8. copy the files to the /usr/lib directory (must use the cp -a to preserve the links)
9. Re-enable atomic updates:

sudo /etc/stellarmate/atomic-updates.sh --enable

There is some possibility that the command from #6 above will put the required files into: /usr/lib/aarch64-linux-gnu directly, in which case you still need to cp -a them into /usr/lib

The required files are shown in the image below


You should now be able to update to TSX 13954 and TSX 14036 (most current Linux ARM64 version as of 10 March, 2026
