I tried to install arm-none-eabi-gdb as a part of gcc-arm-embedded. I added PPA:
sudo add-apt-repository ppa:team-gcc-arm-embedded/ppaand executed:
sudo apt install gcc-arm-embedded It responded with:
Err:8 focal Release 404 Not Found [IP: 91.189.95.83 80]As far as I understand - gcc-arm-embedded doesn't have a version for Ubuntu 20. So I've changed release version for this PPA in Software & Updates to bionic so that I can avoid error 404.
Even though ubuntu 20 has libisl22, now I have unmet dependencies when I try to install gcc-arm-embedded:
The following packages have unmet dependencies: gcc-arm-embedded : Depends: libisl15 (>= 0.15) but it is not installable
E: Unable to correct problems, you have held broken packages.I was unable to find a way to install requested version of libisl, as apt offers only two versions - libisl22 and libisl-dev and both are not accepted by installer.
I need advice on how to install arm-none-eabi-gdb. Thank you!

It turned out that ARM decided to make our life easier (sarcasm) by deprecating the use of PPA - their page at launchpad now has an anouncement: "... all new binary and source packages will not be released on Launchpad henceforth ...".
So, to make use of their latest arm-none-eabi-gdb you have to install gcc-arm-embedded manually.
Remove arm-none-eabi-gcc from your system:
sudo apt remove gcc-arm-none-eabiDownload latest version (Linux x86_64 Tarball) from their website, check its MD5. Unpack it into some directory. I used /usr/share/ :
sudo tar xjf gcc-arm-none-eabi-your-version.bz2 -C /usr/share/
Create links so that binaries are accessible system-wide:
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-g++ /usr/bin/arm-none-eabi-g++
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-gdb /usr/bin/arm-none-eabi-gdb
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-size /usr/bin/arm-none-eabi-size
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopyInstall dependencies. ARM's "full installation instructions" listed in readme.txt won't tell you what dependencies are - you have to figure it out by trial and error. In my system I had to manually create symbolic links to force it to work:
sudo apt install libncurses-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6 /usr/lib/x86_64-linux-gnu/libncurses.so.5
sudo ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5Check if it works:
arm-none-eabi-gcc --version
arm-none-eabi-g++ --version
arm-none-eabi-gdb --version
arm-none-eabi-size --versionThe answer from Aleksander solved 99 percent of my issues, however after running make I got one error arm-none-eabi-objcopy : command not found. So I had do make one more symlink to get the files generated.
sudo ln -s /usr/share/gcc-arm-none-eabi-your-version/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopy
I tried to add this as comment to the answer but I don't have enough points to do that.
1I've wrapped the script here by @kmhallen into a semi-automated debian package builder here:
Installing a package like this means you can skip the tedious manual symlinks to put tools on the path, and just as importantly you can uninstall / upgrade to newer packages (assuming I remember to make more packages)
The toolchain is now only provided on their website:
After extracting, add the path to the bin folder to the system path:
cd /opt
wget ""
tar -jxf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
rm gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
export PATH="/opt/gcc-arm-none-eabi-10.3-2021.10/bin:$PATH"Alternatively, here is a script to generate a Debian package and install it to the /usr directory. This way you don't have to export the path all the time, and it can be removed with sudo apt purge gcc-arm-none-eabi
