Just going through some old bugs while investigating something else in add-apt-repository, and I noticed this bug references LP: #1311056 which I fixed some years ago (but after the last comment on this bug). I'm setting this to incomplete as I suspect the root cause of this is indeed LP: #1311056, which should no longer occur.
If this is still an issue for you, please reset to new, and I'll take a further look. ** Changed in: software-properties (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1841525 Title: apt-add-repository can take machine down Status in software-properties package in Ubuntu: Incomplete Bug description: If apt-add-repository has to work with a file with 20000 entries, even when all but 20 are commented out, it will bring a machine slowly to a halt. IO writes of >100MB/s will happen, so basically saturating all available bandwidth of a rotating disk. This will bring a machine to a stand still due to extreme load.
